CalLite 3.0 has been developed using the Water Resources Integrated Modeling System (WRIMS 2)
software, a modeling framework developed and used by DWR and Reclamation in CalSim modeling.
The advantages of using WRIMS 2 over GoldSim based CalLite and WRIMS 1 are as follows:
•
•
•
Corroboration studies between CalLite and CalSim II will be directly comparable,
because both models have the same solution algorithm and similar assumptions and
data structures.
DWR and Reclamation staff expertise in using WRIMS 2 easily transfers between CalSim
II and CalLite.
WRIMS2 affords the capacity to add new features in the future such as daily time step
modeling, reservoir routing, Monte Carlo simulation, or a dynamic link library (DLL) for
groundwater simulation.

CALLITE DOCUMENTATION VERSION 3.00
Other important features of the CalLite model are:
•
•
•
•
•
Run time is much shorter than CalSim II (about 6 minutes on an up-to-date modeling
computer), because of lumped hydrology and a reduced number of solution cycles.
An intuitive Java-based Graphical user Interface (GUI) allows both novice and expert
modelers to construct scenarios, post process and view results.
The GUI can be easily modified to accommodate future regulation changes and model
capabilities.
The ability to run independently of the GUI allows the use of pre-processing scripts to
automatically parameterize and run of a large number of studies in a short amount of
time.
The results obtained from a typical CalLite run are within 1% of a corresponding CalSim
run.

1 Introduction
California is experiencing unprecedented pressures on its water resources and water infrastructure.
Recent issues such as the Sacramento-San Joaquin Delta (Delta) ecological crisis, court-mandated
cutbacks due to endangered species concerns, and southwest drought have combined with longerterm issues such as population growth and climate change to create a tenuous water supply picture
in California. Various state, federal, and regional planning processes are considering significant
changes to California water management to improve water supply reliability, protect fisheries and
enhance ecosystems, and improve water quality.
In 2007, DWR and Reclamation embarked on the development of a rapid, interactive screening
model for Central Valley water management. DWR and Reclamation identified the need for a tool
that bridges the gap between more detailed system models managed by these agencies and
policy/stakeholder demands for rapid and interactive policy evaluations. This screening model,
named CalLite, simulates the hydrology of the Central Valley, reservoir operations, SWP and CVP
operations and delivery allocation decisions, existing water sharing agreements, and Delta salinity
responses to river flow and export changes. The existing hydrology and operations planning model,
CalSim II (Munévar and Chung 1999, Draper et al. 2004), was used to provide aggregated hydrology
and guidance on system operating rules, and previously developed Artificial Neural Networks (ANNs)
were embedded in CalLite to simulate Delta flow-salinity relationships.
CalLite simulates water conditions in the Central Valley over an 82-year planning period (water years
1922-2003) in about 6 minutes and allows interactive modification of a variety of water
management actions including enlargement of existing storage facilities, demand management, and
river and Delta channel flow and salinity targets. In addition, CalLite can simulate observed or
possible future hydrologic regimes to enable the user to determine climate change impacts. The tool
is designed to assist in the screening of a variety of water management options and for use in a
variety of stakeholder processes for improved understanding of water system operations and future
management.
The first version of CalLite (Version 1.00R) was released in July 2008, followed by Version 1.10R in
February 2009. This documentation describes the development, structure, and use of the newest
version of the CalLite model (Version 3.00). While Versions 1.00 and 1.10 of were implemented in
the GoldSim modeling platform (Islam et al. 2011), Versions 2.00 and 3.00 are implemented using a
simulation engine developed using WRIMS 2, and a customized GUI that replicates the functionality
contained in previous versions of CalLite.
The first several sections of this document provide the general context and role of screening models
in California water planning and outline the objectives in the development of CalLite. The modeling
platform and model representation of the physical system are then described, including a discussion
of the differences between CalLite and CalSim II. This discussion is followed by a description of the
hydrology and system operations (including regulations) included in the CalLite model, which is
supported by a detailed hydrology development appendix (Appendix A). Several innovative features
of CalLite are then described in detail. Comparisons of CalLite and CalSim II model results are
provided in order to illustrate the consistency of the two models. Finally, this document includes a
discussion of limitations of the CalLite model and associated data sets and provides future directions
3
CALLITE DOCUMENTATION VERSION 3.00
that are being considered by DWR and Reclamation. Appendices provide additional detail on such
topics as regulatory controls, sea level rise, delivery allocation procedures, and model assumptions
as compared to CalSim II.
While CalLite simulates the hydrology and operations over much of the same geographic area as the
CalSim II model, there are several features in the CalLite screening model that are unique and are
highlighted here. These innovative features or capabilities permit a range of analyses to be
conducted that are distinct from those that can be reasonably performed in existing system models.
These features are highlighted here and documented further in Section 7 of this report.
Rapid runtime and interactive interface
CalLite simulates monthly water conditions in the Central Valley over an 82-year planning period in
approximately 6 minutes and allows interactive access to simulation controls and results. While
short runtime is not a benefit in of itself, it does allow many more alternatives or trials to be
explored, and is necessary for any reasonable analysis of uncertainty. Interactive controls and
output displays allow the CalLite model to be accessible to a broader user-base.
Delta requirements and facility controls
CalLite incorporates a flexible approach for allowing user-selection and specification of Delta
requirements to be implemented in simulations. A menu of existing and potential future Delta
requirements has been developed. CalLite users may also specify alternative values for various
controls. The Delta controls allow for inclusion and specification of user-defined Old and Middle
River (OMR) and QWEST flow restrictions.
Demand management options
CalLite currently incorporates both “current” and “future” levels of demand as established in the
Common Assumptions Common Model Package (Version 9B) (DWR 2009). However, an option also
exists for user-specified SWP and CVP south of Delta demands. This capability allows for exploration
of demand management in the export area.
Sea level rise simulation capabilities
In addition to modeling Delta conditions under historical sea levels, CalLite also has two options for
sea level rise associated with global climate change (15 centimeter (cm) and 45 cm rise).

2 California Water Planning and Role of
Screening Models
Many existing computer models are applied for California water planning and management. The
capabilities of these models cover a wide range of analysis categories: hydrology, system operations,
hydraulics/hydrodynamics, water quality, lake and river temperature, groundwater, ecosystems,
agricultural water use, fish mortality, economic optimization, and others. Due to the complex nature
of California’s Central Valley water resources system, each of these existing models is necessarily
detailed in order to capture specific system responses. These tools are important to the
understanding of physical processes and play a critical role in California water planning.
A typical application of these models in a water management setting is as follows: (1) policymakers
are faced with water management problems and request technical support, (2) technical teams are
formed and develop a list of studies to be performed, (3) modeling teams develop simulations for
specific resource areas, and (4) results of these model simulations are processed, analyzed, and
summarized for policymakers and stakeholders. This process is generally repeated several times
until the questions have been framed properly and sufficient information has been developed to
make informed decisions.
Many of the problems (and solutions) facing California water today are ill-defined and require
significant exploration of the decision space and causal relationships. Often, existing tools are not
well-suited for exploratory analysis due to issues such as long runtimes, lack of multi-disciplinary
dynamic linkages, limited accessibility for non-technical stakeholders, and lack of immediate
graphical responses to specified management scenarios. This gap in the array of available analytical
tools is what motivated the development of CalLite.
CalLite is designed for use in a variety of stakeholder processes for improved understanding of water
system operations and management. The tool bridges the gap between more detailed system
models, such as CalSim, maintained by DWR and Reclamation, and policy and stakeholder demands
for rapid and interactive policy evaluations. The role of the screening model along with key
characteristics in terms of complexity and ease of use is illustrated in Figure 1. As shown in Figure 1
(a), the models at the top of the pyramid allow exploration, user interaction, and are accessible to
non-expert modelers. In contrast, the models at the bottom of the pyramid are highly complex and
require expert modelers to operate.
Figure 1 (b) briefly depicts the relationship between CalLite and the other modeling tools used and
managed by DWR and Reclamation. CalSim is the Central Valley-wide water system detailed model,
which requires input such as hydrology, demands, regulations, and operational constraints. The
outputs (i.e., river flows, reservoir storage etc.) from the CalSim model are used as input boundary
conditions to the physically based models (Delta Simulation Model II (DSM2) and Integrated Water
Flow Model (IWFM)). The flow and salinity outputs from DSM2 are used to train an Artificial Neural
Network (ANN), which is then used by the CalSim and CalLite models to rapidly replicate DSM2
results during simulations. CalLite uses hydrologic and demand timeseries data from a base CalSim
run as inputs, which allows it to closely replicate CalSim results under different modeling
5
CALLITE DOCUMENTATION VERSION 3.00
assumptions. Lastly, final alternatives generated from a CalLite screening analysis are modeled in
more detail using CalSim, when producing final results for environmental impact analyses or
feasibility studies and reports (Islam et al. 2011).
CalLite includes the most important dynamic system responses, but simplifies or aggregates less
important system features. CalLite is not a replacement for existing detailed and complex models,
but rather is informed by the data and results of existing models and allows users to explore future
water management actions, improve understanding, and support more stakeholder-involved
decision-making. CalLite allows screening of a suite of alternatives to identify a smaller subset to be
incorporated into more detailed models. In this sense, CalLite becomes part of a portfolio of
analytical tools that range in complexity and stakeholder accessibility.

3 Modeling Platform
Version 3.00 of the CalLite screening model consists of a simulation engine produced using WRIMS 2
in executable form (.exe) and a standalone GUI that allows the user to design and run scenarios and
view model results. WRIMS 2 is the generalized Water Resources Integrated Modeling System
software for evaluating operational alternatives of large and complex river basins (DWR 2011). It
was originally developed to implement the CalSim II model. WRIMS 2 uses a linear programming
(LP)/mixed integer linear programming (MILP) solver to determine an optimal set of decisions for
each time period given a set of relative weights and system constraints. The system constraints and
weights are specified using the Water Resources Engineering Simulation Language (WRESL) (DWR
2000a, 2000b). For Version 3.00 of CalLite, WRESL code was written to implement a simplified
version of the system simulated in CalSim II, thereby reducing run time while still maintaining the
key features of the system.
3.1 Structure of WRIMS 2-based CalLite
Figure 2 shows the design of the new WRIMS 2-based version of CalLite. The code for the model is
written in WRESL, and WRIMS 2 is used to compile that code into an executable (CalLite.exe) which
performs all of the model calculations. The distributed version of the model includes this executable
together with the CalLite GUI. The user uses the CalLite GUI to design scenarios and specify any
customized settings desired. When the user clicks the button to run a scenario, the GUI first creates
a temporary folder and copies the appropriate input files and libraries into that folder. The GUI then
calls CalLite.exe and runs the scenario. Outputs from CalLite.exe are stored in the Hydrologic
Engineering System Data Storage System (HEC-DSS) - the same format as CalSim II. After the run is
completed, the user can use the GUI to view these outputs in graphical and tabular format.
While most of the interactions shown in Figure 2 will be invisible to the user, use of WRIMS 2 and
WRESL will allow model developers to make changes as needed to the CalLite.exe simulation engine.
For example, changes could be made to add different management or regulatory options or update
code to improve calculations or consistency with CalSim II. Likewise, the CalLite GUI can also be
customized by developers in parallel with changes in the simulation engine. The GUI.xml file and GUI
linking tables (see Figure 2) are used to specify the GUI options that will be available for a given
version of CalLite. In addition to facilitating the normal process of updating and improving the
software as time goes by, these features will enable developers to create customized versions of
CalLite for different users and for different purposes.

between the user and the technical components.
3.2 CalLite Utilities
A number of utilities complement the CalLite WRIMS 2 model and GUI. These are summarized here
and described in more detail in the appendices:
CS2CL (“CalSim to CalLite”) tool. This is a WRIMS 2 model that is used to create timeseries inputs to
the CalLite model. These inputs include inflows and accretion-depletion terms listed in Appendix A,
along with many other timeseries used by CalLite. These timeseries are either directly imported
from CalSim II input and output, or they are new timeseries that are calculated from the CalSim II
timeseries and additional factors. In versions of CalLite prior to Version 2.00, these timeseries were
developed using MS Office Excel spreadsheets, but this method proved tedious and error-prone.
Generating these timeseries in a WRIMS 2 model has a number of advantages, including consistency
in coding with CalLite itself, generation of a record of exactly how timeseries are generated, easier
updating of timeseries and tracking of changes, and automation of the procedure for generating
timeseries. More details about the CS2CL model are available in Appendix H.
Running CalLite WRIMS 2 model without the GUI. For greater customization and flexibility, the
CalLite model can also be run manually (i.e. without the GUI). Appendix I describes the procedure
for doing this, which involves modifying input text files and double-clicking on a Windows batch file
to run the model. One potential use of this manual run capability would be to set up and batch run a
very large number of CalLite studies, which could be more efficient than having to parameterize and
run each individual study through the GUI.
9
CALLITE DOCUMENTATION VERSION 3.00
CalLite Report Tool. The report tool is a quick and easy way to compare the results of two CalLite
studies, two CalSim studies, or a CalLite study to a CalSim study. The report tool can be run using the
External PDF tab in the CalLite GUI. By default the CalLite GUI will display a standard report that
compares two CalLite studies, but this report can also be customized by editing a template file that
accompanies CalLite. Appendix J describes how to use the report tool and how to edit the template
file to create other customized reports.
10
CALLITE DOCUMENTATION VERSION 3.00
4 Model Representation of the Physical
System
CalLite represents the Central Valley water resource system based on a simplified network. The
simplified network was developed in cooperation with SWP and CVP operators and planners in
terms of criteria that tend to control project operations. Once these controls were agreed upon and
the level of spatial complexity was determined, aggregation of the planning-level hydrology from
the existing CalSim II model was developed to produce the CalLite model hydrology. The relationship
between the CalSim II and CalLite hydrology is maintained through the pre-processing tool (CS2CL)
described in the preceding section. This pre-processing tool can be used to synchronize the
hydrology between the two models as changes are made to both models in the future. The physical
system is shown in Figure 3 and the resulting CalLite network is shown in Figure 4. Figure 42, Figure
43, and Figure 44, in Appendix A show parts of the schematic at a larger scale that is easier to read.
North of the Delta, the schematic in Figure 43 is almost identical to the schematic used in Version
1.10R of CalLite, except that two nodes on the Yuba River upstream of Daguerre Point Diversion
Dam that were in Version 1.10R are not included in the newest version of CalLite. In the Delta and
south of the Delta, Version 3.00 has a more detailed schematic than earlier versions of CalLite. This
additional detail is needed to properly model and understand the implications of different water
management alternatives in those areas.

CALLITE DOCUMENTATION VERSION 3.00
4.1 River Basins Incorporated
The CalLite screening model incorporates a simplified version of the CalSim II schematic as the basis
for the system configuration and identification of operational constraints. CalLite incorporates the
hydrology and operation of the upper Trinity River, Sacramento River, lower Feather River, lower
Yuba River, lower American River, and the Delta. The hydrology of the Sacramento Valley and the
Delta and treatment of SWP and CVP demands are described in detail in Appendix A. With CalLite
3.0, users have the option to run a study with either a fixed or a dynamic SJR system. Under a fixed
system, the San Joaquin River and its tributaries will not be simulated in CalLite. Instead, the inflow
to the Delta from the San Joaquin is set equal to the flow at Vernalis as computed by CalSim II.
Under a dynamic SJR system, the San Joaquin River, its tributaries, and the major storage facilities in
that basin are modeled during the simulation. SJR regulations can also be modified by the user when
CalLite is run with the dynamic SJR system.
4.2 Major Storage and Conveyance Facilities
Table 1 lists all the major storage and conveyance facilities represented in CalLite. All major facilities
included in CalSim II in the Sacramento Basin are represented here, except for New Bullards Bar and
Engelbright reservoirs on the Yuba River. The configuration of the Delta and facilities just south of
the Delta (i.e. Banks and Jones Pumping Plants) is identical to that in CalSim II. The representation of
the Delta Mendota Canal (DMC), California Aqueduct, and San Luis Reservoir remains largely
consistent with CalSim II, though the schematic is more aggregated.
4.3 Sacramento Valley Hydrology Aggregation
Hydrologic inputs for the major reservoirs in CalLite are identical to those used in CalSim II.
However, the valley floor river accretions and depletions were aggregated to match the reduced
CalLite schematic. The hydrology and water management in the Sacramento and San Joaquin valleys
is extremely complex as water is diverted from streams and rivers, applied to agricultural and urban
areas, and often reused before returning to the surface water system through drainage networks.
Since the current focus of CalLite is to explore regional and cross-Delta water management actions,
much of the valley floor stream/drainage network and water supply system was simplified. In
CalLite, SWP and CVP contractor diversions are simulated dynamically and surface water is delivered
to these users based on allocation logic. In contrast, non-project diversions are pre-determined and
set equal to non-project diversions in CalSim II. These simplifications led to a significant reduction in
the complexity of the network. All hydrology for both the CalLite and CalSim II models is specified on
a monthly basis for an 82-year planning period. Appendix A describes the hydrology development
for CalLite in detail.
4.4 South of Delta Export Area Demand Aggregation
The representation of the DMC, California Aqueduct, and San Luis Reservoir is largely consistent
with CalSim II, but spatial extent and contractor diversity are simplified. Demands and deliveries to
the SWP and CVP south of Delta contractors have been aggregated into a smaller number of delivery
points. While Version 3.00 of CalLite aggregates CalSim II deliveries and facilities south of the Delta,
the system is represented in greater detail than it was in Version 1.10R of CalLite, especially south of
14
CALLITE DOCUMENTATION VERSION 3.00
Dos Amigos Pumping Plant, which the earlier version of CalLite did not portray. Joint use operations
and the Mendota Pool are also represented in Version 3.00 of CalLite in more detail than in previous
versions of CalLite.
4.5 Regulatory Constraints

interface. Options are also available to simulate regulatory standards based on the Reasonable and
Prudent Alternatives (RPAs) in the Fish and Wildlife Service (FWS) and National Marine Fisheries
Service (NMFS) Biological Opinions (BOs) (FWS 2008, NMFS 2009). Details regarding the Delta
regulatory constraints in D-1485, D-1641, and the BO RPAs are described in Appendix C. Appendix D
has more information on the Sacramento Basin instream flow standards listed in Table 1.
Implementation of these standards and operations to satisfy the requirements are identical to those
in CalSim II.

CalLite 3.00 includes the capability to simulate several possible future water management actions.
Currently, users may simulate an enlargement of Shasta and of Los Vaqueros. CalLite includes only
skeletal implementations of these facilities and the results should be considered draft. The future
water management actions are discussed further in Appendix B.

CALLITE DOCUMENTATION VERSION 3.00
5 Regulatory Environment
State Water Board Decision 1485 (D-1485) was issued in August of 1978 to protect vested water
rights and the public interest. The underlying principal of D-1485 is that “water quality in the Delta
should be at least as good as those levels which would have been available had the state and federal
projects not been constructed. The D-1485 standards aim to protect the beneficial uses of the
water of the Sacramento-San Joaquin Delta (Delta) and Suisun Marsh. The State Water Resources
Control Board (Board) did not intend to resolve the water quality problems in the southern Delta
through D-1485 because the Board agreed that the SWP and CVP facilities covered by the permits
before the Board in the D-1485 proceedings did not appear to have a direct impact on water quality
conditions in the southern Delta.
D-1485 modified the permits held by the Bureau of Reclamation (Bureau) and the Department of
Water Resources (DWR) and established water quality standards to follow. All burden of meeting
the standards was placed on the SWP and CVP, but no priority was established between the two.
The Board declared that: “water quality standards in the Delta must be satisfied prior to any export
from the Delta to other areas for any purpose [and that] these standards must be maintained as first
priority operating criteria”.
In 1986, the Racanelli Decision overturned D-1485 because its use of “pre-project construction”
conditions as a measure of flows needed to protect existing water rights in the Delta focused on
water rights instead of beneficial uses. The courts also concluded that the use of “pre-project
construction” conditions was invalid because it placed all responsibility on the CVP and SWP and
ignored other Delta water rights holders.
Thirteen years later, in 1999, State Water Board Decision 1641 (D-1641) was issued and has
continued to be the overlying water quality regulation for the water projects. Its primary purpose
was to allocate responsibility for implementing the flow-dependent objectives of the 1995 Bay-Delta
Plan. D-1641 sets today’s minimum outflow requirements for the Delta, delta cross channel
operations, minimum river flows at Rio Vista, X2 requirements for salinity control, export restrictions
through the export-inflow ration and Vernalis criteria, and salinity standards at Emmaton, Jersey
Point, Rock Slough, and Collinsville.
The biological opinions (BOs) implemented in CalLite are the Reasonable and Prudent Alternatives of
the U.S. Fish and Wildlife Service (USFWS) Operational Criteria and Plan (OCAP) Delta Smelt BO
(issued December 2008) and the National Marine Fisheries Service (NMFS) OCAP Salmonids BO
(issued June 2009). In CalLite these BOs set: minimum flow requirements below Whiskeytown Dam
at Clear Creek (NMFS Action 1.1.1), additional X2 salinity requirements (FWS Action 4), additional
closure of the delta cross channel gates during flushing flows in Oct-Dec (NMFS Action 4.1.2), flow
restrictions at Old and Middle River (FWS Actions 1-3), limited CVP and SWP exports in April and
May (NMFS 4.2.1), and minimum flow requirements below Goodwin Dam on the Stanislaus River
(NMFS 3.1.3).

6 Simulated Operations of Existing
Facilities
While many aspects of the Central Valley's water resources system were simplified for
implementation in CalLite, some parts of the model are identical to CalSim II model. These areas
include (1) aspects governing operation and control of Delta facilities, water quality, and channel
flows; and (2) delivery allocation procedures for the CVP and SWP. A useful reference on CalSim
assumptions, many of which are replicated in CalLite, is the report on the Common Assumptions
Common Model Package (Version 9B) (DWR 2009).
6.1 Upstream Reservoirs and Operations
A list of the operational criteria used in CalLite, is included below.

CALLITE DOCUMENTATION VERSION 3.00
6.1.1.5 Trinity-Shasta-Folsom Balancing
The balancing of storage between Trinity, Shasta, and Folsom reservoirs in CalLite is done using the
same criteria as in CalSim II. Storages in these reservoirs are balanced through model weights that
encourage equivalent storage zones in the three reservoirs to be filled to the same proportional
level, all else being equal. The weights encouraging zone balancing are relatively low, so that
reservoir balancing will not take priority over other project operations.
6.1.1.6 NOD-San Luis Storage Balancing
CVP north of Delta storage is balanced with storage in San Luis Reservoir using the same CVP San
Luis rule curve criteria established and applied in CalSim II. If CVP San Luis storage is below rule
curve, the model weights encourage water to be pulled from CVP north of Delta reservoirs down to
CVP San Luis. When storage is above the rule curve, priority is given to leaving water in storage
north of Delta. The CVP San Luis rule curve usually peaks in April or May and is at its lowest in
September, and is higher in wet years and lower in dry years.
6.1.2 SWP Reservoirs and Operations
6.1.2.1 Oroville/Thermalito Reservoirs and Operations

Hydropower Operations
6.1.2.2 Oroville-San Luis Storage Balancing
Oroville storage is balanced with storage in San Luis Reservoir using the same CVP San Luis rule
curve criteria established and applied in CalSim II. Oroville-San Luis balancing criteria is similar to
that described for CVP above.
6.2 Delivery Allocation Decision-Making
Delivery allocations for the CVP and SWP are calculated by either the Water Supply Index – Delivery
Index (WSI-DI) Method or the Forecast Allocation Method (FAM).
The WSI-DI method is the procedure currently used in CalSim II. This logic develops an allocation
decision for system-wide CVP and SWP deliveries based on water in storage, forecasts of usable
inflow, and storage carryover targets. The allocations for the CVP Water Right, Exchange, and
Settlement contractors and SWP Feather River Service Area contractors are dependent on reservoir
inflow criteria. South-of-Delta delivery allocations for the CVP are based on water in CVP San Luis
storage plus projections of available water for export prior to low point. This is identical to the
current procedure used in CalSim II.
FAM is developed based on the California Allocation Module (CAM). The model is developed by
utilizing the multi-step optimization functions in WRIMS 2. FAM is coupled with the CalLite model by
working as an additional cycle.
Appendix G describes these allocation procedures in more detail.
21
CALLITE DOCUMENTATION VERSION 3.00
6.3 Coordinated Operations Agreement
The Coordinated Operations Agreement (COA) (USBR and DWR 1986) assigns responsibility for
releases for in-basin uses or apportions available water for export to the CVP and SWP depending on
the hydrologic conditions. If stored water must be withdrawn from project reservoirs to meet inbasin uses (including Delta requirements), the responsibility for releases is shared in the ratio 75:25
between the CVP and SWP, respectively. Under conditions in which unstored water is available for
export (exports exceed project storage withdrawals), the water is shared in the ratio 55:45 between
the CVP and SWP, respectively. If one party cannot use its entire share of water under the COA, the
other party is permitted to use the unused share. The COA is implemented in CalLite in exactly the
same way as in CalSim II.
6.4 Delta and Export Operations
6.4.1 Delta Requirements and Export Controls
Delta requirements and export controls are implemented in the same manner as in CalSim II. Due to
the importance and scrutiny of these requirements and operational control, they are summarized in
Section 7.4 and described in detail in Appendix C and Appendix D. In addition to the minimum health
and safety pumping rates described for Jones and Banks below, export caps associated with BO RPA
actions cannot be reduced below 1500 cubic feet per second (cfs) for both pumping plants
combined. This is to avoid rapid drawdown of San Luis Reservoir for dam safety reasons, which
could occur under situations where supplies are available and allocated but exports are constrained
by the RPAs.
6.4.2 Jones Exports
Exports at Jones Pumping Plant are governed by the need to meet demands on the Delta Mendota
Canal and San Luis Unit, desired storage levels for CVP water in San Luis Reservoir, availability of CVP
water for export in the Delta, regulatory limits, and physical capacity of the pumping plant and the
conveyance facilities. The target pumping level is determined by a CVP south of Delta demand which
includes demands from both contractors and for maintaining CVP San Luis target storage levels.
Export limits due to regulatory controls then serve as a cap on total project exports. In the current
CalLite version, the allowable export curtailments are shared 50/50 between the SWP and the CVP.
A minimum pumping rate of 800 cfs is applied for health and safety requirements. The minimum
pumping rate is reduced to 600 cfs when storage in Lake Shasta is less than 1500 thousand acre-feet
(TAF), to conserve storage in Shasta.
6.4.3 Banks Exports
Exports at Banks Pumping Plant are subject to similar controls as Jones Pumping Plant: demands on
the California Aqueduct, desired storage levels for SWP water in San Luis Reservoir, availability of
SWP water for export in the Delta, regulatory limits, and physical capacity of the pumping plant and
the conveyance facilities. The target pumping level is determined by the SWP south of Delta demand
which includes demands from both contractors and for maintaining SWP San Luis and terminal
reservoirs at target storage levels. Export limits due to regulatory controls then serve as a maximum
22
CALLITE DOCUMENTATION VERSION 3.00
on total project exports. In Version 3.00 of CalLite the allowable export curtailments are shared
50:50 between the SWP and the CVP. A minimum pumping of 300 cfs is applied for health and safety
requirement.
6.5 South of Delta Operations
6.5.1 CVP Delivery Allocations
6.5.1.1 Delivery Allocations
Overall CVP delivery allocations are made through the water supply index approach. This allocation,
or delivery target, is specified as the sum of all CVP contractor categories. A separate process,
identical to that in CalSim II, performs the assignment of water to specific contractor types or
categories. A tiered reduction scheme is employed so that contractor allocations match the overall
delivery allocations (DWR 2009), as shown in Table 3. The model proceeds sequentially through
each tier until sufficient cuts have been made. In addition, exchange contractor deliveries are always
cut from 100% to 77% when the Shasta water year type is critically dry. Agricultural, municipal and
industrial (M&I), refuge, and exchange contractor demands are then satisfied at the appropriate
delivery location.
Table 3. CVP cutback tiers for agricultural and M&I deliveries.

100% to a minimum of 75%

Tier 4
25% to a minimum of 0%
M&I contractor cuts

75% to a minimum of 50%
6.5.2 SWP Delivery Allocations
6.5.2.1 Table A Allocations
As with the CVP, overall SWP delivery allocations are made through the water supply index
approach. This allocation, or delivery target, is specified as the sum of all SWP Table A contractor
categories. Any reductions to Table A allocations that are required to match the overall SWP delivery
target are shared in proportion to the Table A entitlement of the contractor category. CalLite
aggregates demands from the 29 SWP contractors in three general categories: Agricultural, M&I –
MWDSC (Metropolitan Water District), and M&I – Other contractors.
6.5.2.2 Article 56 Deliveries
Article 56 deliveries refer to SWP contractor deliveries that were allocated in the previous year, but
were stored in SWP storage before being delivered in the current year. SWP contractors sometimes
defer taking the allocated water in wetter years in the hopes that the delivery of water in the
subsequent year would prove more beneficial. CalLite incorporates an accounting scheme for the
Article 56 water in storage and provides this for delivery in the subsequent year to each eligible
contractor (DWR 2009).
23
CALLITE DOCUMENTATION VERSION 3.00
6.5.2.3 Article 21 Deliveries
Article 21 deliveries are made by the SWP when excess water is available in the Delta, SWP share of
San Luis Reservoir storage is full, SWP Table A and Article 56 deliveries have been satisfied, and
Banks Pumping Plant has available capacity for additional pumping. The delivery of Article 21 water
in CalLite is simulated by allocating water to a series of contractor-specific interruptible deliveries
which are only satisfied if all of the above conditions are met.
6.5.3 San Luis Reservoir Operations
The operational objective of San Luis Reservoir for both projects is to maximize storage in the early
spring to help meet the high water demands in the late spring, summer, and early fall. Reservoir
filling generally occurs December through April while the drawdown period is generally May through
November. The projects generally rely upon winter and spring flows in the Delta to fill San Luis
Reservoir, however, they will also make storage withdrawals from upstream reservoirs during this
period to ensure that there is sufficient water in San Luis Reservoir to meet future demands and
storage targets. The operation of the CVP, due to greater constraints on upstream reservoirs and
limited Jones Pumping Plant capacity, generally limits the ability to significantly control San Luis
Reservoir storage during the fill period; exports are maximized until the CVP share of San Luis
Reservoir is full or upstream storage is limited. During the fill cycle, San Luis Reservoir rule curves for
both the SWP and CVP are applied for each project based on available upstream storage and initial
project allocations, per CalSim II assumptions. As in CalSim II, rule curves are used to balance north
of Delta supplies with San Luis Reservoir storage (DWR 2009).
6.5.4 Wheeling
6.5.4.1 Cross Valley Canal Wheeling
Deliveries to Cross Valley Canal (CVC) contractors are subject to the CVP south of Delta agricultural
water service allocations described in Section 6.5.1.1. However, unlike other south of Delta CVP
deliveries, CVC contract supplies are not drawn through Jones Pumping Plant or from San Luis
Reservoir; it is wheeled through the SWP’s Banks Pumping Plant and the California Aqueduct. CVC
deliveries are limited by available conveyance capacity after SWP operations. Capacity is typically
available in the summer or fall. In CalLite, CVC wheeling occurs in a separate cycle after determining
SWP exports at Banks Pumping Plant and SWP south of Delta deliveries.
6.5.4.2 Payback Wheeling
D-1485 regulation restricts the CVP to mean monthly exports of only 3,000 cfs in May and June.
Under Condition 3 of D-1485, the CVP is allowed to make up any deficiencies caused by the
limitation by direct diversion or by re-diversion of releases of stored water through State Water
Project facilities. Exhibit D of COA (see Section 6.3) lays out an exchange procedure to minimize the
impact of the limitation on CVP and SWP power operations. In CalLite, payback wheeling is only
turned on for a D-1485 run; it does not apply to D-1641 runs. Payback wheeling occurs the separate
wheeling cycle of CalLite.
6.5.4.3 Joint Point of Diversion
The Joint Point of Diversion (JPOD) is another mechanism by which the CVP wheels water through
Banks Pumping Plant. Water wheeled under JPOD supplements Jones Pumping Plant exports by
filling the CVP share of San Luis Reservoir and meeting CVP contractor delivery targets. JPOD has
24
CALLITE DOCUMENTATION VERSION 3.00
lower priority than SWP exports and CVC wheeling. In CalLite, JPOD wheeling only occurs if Jones
Pumping Plant or Upper Delta-Mendota Canal capacity is being fully utilized. When the Delta is in
surplus conditions, JPOD occurs when SWP San Luis is full, the SWP is meeting all Table A and Article
21 delivery targets, and there is still remaining capacity at Banks Pumping Plant. When the Delta is in
balanced conditions, the SWP first uses Banks Pumping Plant as needed and, if there is remaining
export capacity and the CVP would like to transfer water from NOD storage to SOD, JPOD can be
used. In CalLite, JPOD occurs the separate wheeling cycle after locking in SWP operations.
6.6 San Joaquin River Controls
The controls on this tab relate to operation of the dynamic San Joaquin module of CalLite. Checking
the top checkbox will activate this module. If this checkbox is not checked, the flows on the San
Joaquin at Vernalis (where it enters the Delta) will be represented as a fixed timeseries, and the
other checkboxes will have no effect. The dynamic San Joaquin module allows for adjustment of
certain regulations that apply to the San Joaquin basin, in particular to New Melones Reservoir on
the Stanislaus River. Activating the appropriate checkbox will activate each of the regulations.
Note that regulations in the San Joaquin basin are currently under review. The two pulse period
regulations listed below (VAMP and the 60-day pulse flow RPA) are not implemented in current
operations in the San Joaquin basin, but are options in the model because new pulse period flow
requirements have not been clearly defined.
The regulations on this tab are as follows:
6.6.1 Vernalis D-1641 Baseflows
This activates the D-1641 flow requirements at Vernalis during February to June (excluding the April
15 - May 15 pulse period). These requirements vary by water year type and whether X2 is located
east or west of Chipps. Any additional water needed to meet these requirements above the flows
required for other regulations is released from New Melones Reservoir, with a cap on releases in dry
conditions.
6.6.2 Vernalis D-1641 Salinity Criteria
This activates the D-1641 salinity requirements at Vernalis, which are 0.7 Electrical Conductivity (EC)
during April-August and 1.0 EC during September-March. Any additional water needed to meet
these requirements above the flows required for other regulations is released from New Melones
Reservoir, with a cap on releases in extremely dry conditions.
6.6.3 VAMP Pulse Flows (Apr 15-May 15)
This activates flow requirements at Vernalis during the April 15 - May 15 pulse period. These flow
requirements vary depending on whether the model is run with Existing or Future Level of
Development. For Future Level of Development, the flow requirements are based on the Vernalis
Adaptive Management (VAMP) that was implemented from 1999-2011. Water is released to meet
25
CALLITE DOCUMENTATION VERSION 3.00
these requirements from multiple tributaries on a schedule defined in the San Joaquin River
Agreement. For Existing Level of Development the flow requirements are based on the agreement
between Reclamation and Merced Irrigation District which was implemented in 2012-2013.
6.6.4 Vernalis 60-day Pulse Flow RPA (NMFS Action 4.2.1)
This activates a 60-day pulse flow requirement at Vernalis during April and May, which varies by
water year type. This requirement is in the NMFS Biological Opinion released in June 2009. Any
additional water needed to meet this requirement above the flows required for other regulations is
released from New Melones Reservoir, with a cap on releases in dry conditions.
6.6.5 Stanislaus Flow RPA (NMFS Action 3.1.3)
This activates a fish flow requirement on the Stanislaus River which varies by water year type. This
requirement is from the NMFS Biological Opinion released in June 2009.
6.6.6 San Joaquin River Restoration Flows
This toggles the San Joaquin River Restoration flows between interim flows and full flows. Flow
requirements vary by water year type. These flows are released from Friant Dam on the upper San
Joaquin River, and are defined under the 2006 Settlement that led to the San Joaquin River
Restoration Program. Interim flows are designed to allow for collection of data and research prior
to implementation of full Restoration flows.

CALLITE DOCUMENTATION VERSION 3.00
7 Innovative Features
While CalLite simulates hydrology and operations over much of the same geographic area as CalSim
II, there are several features in the CalLite Version 3.00 that are unique. These innovative features or
capabilities permit a range of analyses to be conducted that are distinct from those that can be
reasonably performed in other system models. These features are (1) rapid runtime and interactive
interface, (2) Delta requirements and facility controls, (3) demand management options, and (4)
hydroclimate simulation capabilities, as described in the following sections:
7.1 Rapid Runtime and Interactive Interface
7.1.1 Rapid Runtime
Because CalLite has a simplified schematic and a reduced number of solution cycles (see Appendix
G) compared to CalSim II, it has a much faster run-time. For the same 82 year planning simulation,
CalLite runs in approximately 6 minutes, whereas a CalSim simulation typically takes around 30
minutes.
7.1.2 Interactive Interface
The CalLite model is configured with a graphical user interface (GUI) that serves as the primary entry
point for most users. For more detail on the GUI beyond the summary provided here, see the CalLite
User's Guide, which is contained in the GUI's help system and is also available as a separate pdf
document. The GUI has a series of dashboards which allow the user to control, edit, and run
scenarios and view results (Figure 5). The first six dashboards (whose tabs are gray with black text)
are Run Settings, Hydroclimate, Demands, Facilities, Regulations, and Operations. These dashboards
allow the user to load, run, and save scenarios, and also to select options such as level of
development (2005 or 2020), sea level rise, South of Delta demands, storage facility options,
regulations to be used, and operations.
The five dashboards to the right (whose tabs are white with blue text) are Quick Results, Custom
Results, Map View, External PDF, and Web Map. The Quick Results dashboard allows the user to
view a variety of pre-selected model outputs in either graphical or tabular format, for a single or for
multiple scenarios. Monthly timeseries plots, exceedance graphs, tables of monthly and annual
values, and statistics for different water year types and periods are available on this tab. The Custom
Results dashboard allows the user to create more customized output graphs and tables. The
External PDF dashboard allows the user to generate a standardized pdf report comparing the results
of two scenarios (see Appendix J for more details). The Map View dashboard shows the CalLite
schematic and mass balance of the Delta. The Web Map dashboard contains an embedded internet
browser that allows the user to view CalLite features overlaid on Google Maps. On both of these
dashboards the user can view CalLite results by clicking on the schematic or CalLite feature.

7.2 Hydroclimate Simulation Capabilities
This section describes CalLite’s capabilities to simulate operations using historical hydrology and
different climate change futures.
7.2.1 Direct Observed Hydrology
The traditional approach toward assessing future actions is to make the assumption that the
historical observed hydrologic conditions and sequence are reasonable for use in projecting future
water availability and management. This is the approach that is used in the CalSim II model. CalLite
incorporates the same direct observed hydrology as that used in the CalSim II model. This hydrology
is based on monthly observed flows from October 1922 through September 2003. Under the direct
observed hydrology option, the 82-year simulated hydrologic sequence has hydrologic variability
represented by the observed data.
Ten climate change hydrologic scenarios are also available: Early Long Term (ELT) Q1-Q5 and Late
Long Term (LLT) Q1-Q5. These scenarios are described in more detail in Appendix F.
28
CALLITE DOCUMENTATION VERSION 3.00
7.2.2 Sea Level Rise (SLR)
Increased temperatures cause thermal expansion of the ocean and melt polar ice caps resulting in a
higher sea level. Historical data for the later part of last century seem to validate this theory.
Observed data along the pacific coast shows a change in the amplitude over the same period. CalLite
includes three options for sea level rise (0, 15 cm, and 45 cm) based on the BDCP analysis (BDCP
2012). See Appendix F for more details on the BDCP sea level rise estimates.
7.3 South of Delta Demand Options
To increase the flexibility of CalLite as a screening tool, the user can choose from three different
South of Delta demand options for SWP and two different options for CVP. For SWP the options are
2005 level, 2020 level, or user-defined as shown in Figure 6. Pre-defined data sets are included for
2005 and 2020 level demands. The 2005 level includes a variable annual demand between 3.3 MAF
to 4.2 MAF. The 2020 level is assumed to be Full Table A entitlement demand per assumptions in the
future level studies of Common Assumptions Common Model Package (Version 9B) (DWR 2009).
Figure 6. Demands dashboard for specification of annual south of Delta SWP and CVP
demand levels.

CALLITE DOCUMENTATION VERSION 3.00
The third option for SWP is user-defined demand values (in TAF) up to Full Table A amounts. Under
this option, the user selects the projected demand levels for SWP Agricultural, M&I-MWDSC
(Metropolitan Water District), and M&I-Other contractors. Demand patterns (fractional) are
assumed to be the same as the 2020 level patterns. The user can also select a proportion of
maximum Article 21 (interruptible) deliveries to implement. Under this option, however, Article 56
(carryover) deliveries are set to zero in order to avoid continued delivery of the these categories
when Table A demands are reduced.
For CVP the two options are full contract amount and user-defined. For the user-defined option, the
user selects projected demand levels for CVP Agricultural, M&I, and Refuge contractors. However,
deliveries to Water Right or Exchange contractors are not permitted to be modified.
7.4 Delta Regulatory Controls
The implementation of Delta regulatory controls and associated operations has been a focal point of
CalLite development. The regulatory controls in CalLite allow users to specify requirements for
interior Delta flows, minimum river flows, Delta outflows, export restrictions, and salinity objectives.
Figure 7 shows a map of the Delta with the locations of Delta regulatory controls. The yellow circles
correspond to locations of EC requirements: Chipps Island (CH), Collinsville (CO), Emmaton (EM),
Jersey Point (JP), Rock Slough (RS), Vernalis (VI), Contra Costa (CC), and Clifton Court (CI). The blue
circles represent locations of flow requirements (Q).

CALLITE DOCUMENTATION VERSION 3.00
The methodology used in the implementation of Delta regulatory controls is identical to that used in
the CalSim II model. However, in the CalLite model, the user can switch requirements on or off,
specify Decision 1485, Decision 1641 or BO RPA requirements, or specify new values for the D1485/D-1641 standards and a few other alternative requirements. These user selections are
specified through a Regulations dashboard as shown in Figure 8. If the user chooses to customize
the constraints by clicking the radio button for user-defined, then they can enter values in the table
in the right side of the GUI. This ability to rapidly switch between Delta requirements is an
innovation that does not exist in other models and allows for rapid screening of regulatory benefits
and impacts.
Figure 8. Regulations dashboard in CalLite.
The main Delta regulatory controls included in the CalLite model are shown in Table 4. The Clear
Creek RPA standard is listed because it is available for selection in the GUI, even though it is not a
Delta standard.

Appendix C includes detailed documentation of the main Delta regulatory controls, assumptions,
and method of implementation. Note that when all of the regulations shown in Table 4 are turned
off, CalLite still implements minimum instream flow standards in the Sacramento basin (these are
described in Appendix D).
7.5 Custom Results
The Custom Results Dashboard allows the user to filter and retrieve variables directly from the DV or
SV file, including variables that cannot be selected through Quick Results or Map View. The filtered
variables can be displayed in the same format as those brought up from Quick Results (i.e. the
various kinds of plots and tables). This feature combines the broad range of post-processing features
from Quick Results with the ability to bring up and analyze any variable in the DSS files.
The user can view the data for these variables directly, or they may elect to create derived time
series (DTS) from them. DTS are created by combining two or more time series with basic
mathematical operators and may be custom-tailored to fit the needs of a specific project or
investigation. These DTS can be saved and accessed at a later session.

7.6 Map View
The Map View Dashboard allows users to view the CalLite study results by clicking on the arcs,
nodes, and reservoirs in the CalLite schematic. Users can choose to view results from the standard
schematic or from the mass balance schematic.
The mass balance schematic aggregates schematic arcs into larger categories. These categories,
represented by the red arrows, account for the major inflows, outflows, exports and net
consumption within the Delta. Alongside the major flows are selectable elements for salinity
stations (represented by yellow circles) and flow objectives (represented by blue circles). Clicking on
the Salinity Station will display the salinity at that station along with its respective salinity standard.
Similarly, selecting the blue circles will display the flow at that location with its respective flow
objective.
Controls
To zoom in, hold the ctrl key and draw a box over the area to be enlarged. An alternative way to
zoom in and out is to hold down shift key and right click simultaneously and then move the mouse
forward and back. To pan across the schematic, hold down the shift key and click/drag anywhere in

8 Comparison to CalSim II Model
Simulations
This section is provided from the CalLite Reference manual v2.00, released October 2011. While the
summary numbers have not been updated to match the model being released under version 3.00,
the relative comparison of results remains similar.
In order to identify any differences between CalLite and CalSim II and understand the degree to
which the approximations included in CalLite affect the key system results, the two models were
compared for the 2020 level of development under D-1641 and BO RPA regulatory standards. For a
description of D-1641 and BO RPA regulatory standards, see Appendix C. The comparisons that
follow show system-wide flows for both models for the long-term 82-year period and the critical
drought periods of 1929-1934 and 1987-1992. Storage timeseries and end-of-September
exceedance plots are also provided for all major reservoirs simulated in the system. Delta mass
balances, X2 position, and Rock Slough electrical conductivity (EC) are also compared. Finally, SWP
and CVP contractor allocations are compared between CalLite and CalSim II. Assumptions of the
studies used here are presented in Appendix E.

8.3 Discussion of CalSim II vs CalLite Comparisons
To reiterate, this section is provided from the CalLite Reference manual v2.00, released October
2011. While the summary numbers have not been updated to match the model being released
under version 3.00, the relative comparison of results remains similar.
The comparisons above show a very close correspondence between CalLite v2.01 and CalSim II
model results. Long-term average Delta inflows and outflows, CVP and SWP exports, and flows in
the Trinity, Sacramento, Feather, and American Rivers are almost identical between the two models,
all differing by far less than 1 percent (see Table 5 and Table 6). Differences for these same
parameters are also very small during the 1929-1934 and 1987-1992 dry periods, almost always less
than 1 percent and never more than 2 percent. The only outputs that differ by more than 2 percent
are outputs involving relatively small volumes of water, such as CVP pumping at Banks and SWP
Article 21 and 56 deliveries.
CalLite simulated storage for CVP reservoirs (Trinity, Shasta, and Folsom) and the SWP’s Oroville
reservoir show a very good match with that simulated by CalSim II (see Figure 12 to Figure 17 and
Figure 27 to Figure 32). The model results are very similar both in terms of monthly storage patterns
and also end-of-September storage exceedance graphs. Simulated San Luis storage in CalLite for
both the SWP and CVP also matches the results of CalSim II (see Figure 18 to Figure 21 and Figure 33
to Figure 36), though there is a little more difference here than for the other reservoirs.
Allocation percentages for SWP and CVP contractors are very close, showing that both models are
equally aggressive or conservative regarding delivery allocations (see Figure 22, Figure 23, Figure 37,
and Figure 38).
54
CALLITE DOCUMENTATION VERSION 3.00
Delta flows and exports drive the results for X2 and salinity conditions. The X2 position results from
CalLite also compare well to those in CalSim II (see Figure 24 and Figure 39). Salinity comparisons at
various stations in the Delta indicate that the ANNs respond identically to the external boundary
conditions (Figure 25 and Figure 40). Figure 26 and Figure 41 compare Delta inflows, outflows, and
exports for the two models, which are also very close.

9 Model and Data Limitations
CalLite is intended as a screening model for Central Valley water management. Compared to CalSim
II, CalLite is a simplified model and much of the complexity of the system has been aggregated.
CalLite captures the most prominent aspects of the Central Valley hydrology and system operations,
but simulated hydrology and water management within specific sub-basins has limited detail. As
such, it is important to understand the limitations of the model when applying CalLite for Central
Valley water management screening. The following are some limitations or sources of uncertainty
when using CalLite.
•
Like CalSim II, CalLite runs on a monthly time step, so it cannot simulate phenomena
that occur at finer time scales.
•
Return flows and surface water–groundwater interactions are not simulated
dynamically. The effects of these processes are implicitly contained in the
accretion/depletion terms derived from CalSim II results (see Appendix A). Because
these terms are fixed, CalLite scenarios whose assumptions vary from the CalSim II study
used to develop the accretion/depletion terms may have a greater level of error in these
terms.
•
The simplified schematic omits much of the hydrologic detail present in the larger
CalSim II model.
•
The model is designed to simulate CVP and SWP operations under conditions that are
reasonably close to current conditions in terms of system facilities, operational rules,
and regulations. But CalLite allows the user to significantly change some aspects of the
system, particularly regulations, South-of-Delta demands, and allocation methods.
While such flexibility is desirable for a screening model, the user should be aware that
model error may increase as CalLite settings move further away from current system
conditions and that simulations with assumptions that are drastically different from
current conditions may produce counterintuitive results.

10 On-Going and Future Developments
This document has described the features of CalLite Version 3.00, including options for Delta
standards, simulating sea level rise, Biological Opinion actions and innovative GUI features. The next
development phase of CalLite will add storage and conveyance alternatives, habitat restoration, and
conjunctive use. A final addition will be improved allocation procedures. Reclamation and DWR are
currently refining the methodology for delivery allocation to include forecast information that is
consistent with that used by the Reclamation Central Valley Operations Office (CVO) and the DWR
Operation and Maintenance Division (O&M).
In addition to these near-term CalLite refinements, DWR and Reclamation expect to utilize and
develop the CalLite and CalSim II models in tandem. Features and operations initially explored using
CalLite in interactive sessions with operators and stakeholders may eventually be transferred to the
more detailed CalSim II model. Similarly, the development and refinement of the CalSim II model
will continue to support many planning efforts, and periodically the hydrology and operating criteria
in CalLite may need to be re-synchronized with CalSim II, if applicable. It is recommended that a
review of the two models be performed annually, or at significant release points, to determine
whether revisions to either model are warranted.
The CalLite modeling platform could also permit loose integration with a number of more detailed
models of specific resource areas. The current integration with the flow-salinity ANNs is a good
example. In this example, the hydrodynamics and water quality response of the DSM2 model is
loosely coupled to CalLite through the use of the ANN. Other models, or response functions based
on these models, could be coupled to allow simulation of groundwater conditions (C2VSIM model);
power generation, consumption, and greenhouse gas emissions (LTGEN model); salmon life-cycle
and mortality analysis, and regional economics (LCPSIM model).
Currently, CalLite simulations are deterministic in nature. In the future, the model will be adapted to
run in probabilistic and position analysis mode to perform stochastic and Monte Carlo type
simulations. Stochastic analysis would be particularly useful in CalLite because results obtained from
several hundred stochastic runs could be compiled in a relatively short period of time. Stochastic
analysis is common practice in simulating climate change scenarios. Finally, CalLite will be adapted
to use an alternative daily time step. The objectives of this implementation are: (1) to simulate daily
reservoir releases (optimized for minimum flow required for fish and water quality, and for flood
control downstream); (2) to simulate weir flows at a daily time step; and (3) to simulate SWP/CVP
Delta operations (export and delta cross channel) at a daily time-step.

Appendix A Hydrology Development
Documentation
The purpose of this appendix is to provide information regarding the assumptions and development
of the hydrology inputs to CalLite. A useful reference on CalSim assumptions, many of which are
replicated in CalLite, is the report on the Common Assumptions Common Model Package (Version
9B) (DWR 2009).
A.1 General Approach
A.1.1
Introduction
Because the CalLite schematic is greatly simplified compared to CalSim II, CalLite input hydrology is
also aggregated and simplified. Figure 42, Figure 43, and Figure 44 (at the end of this appendix)
show the CalLite schematic. Sub-sections of the CalSim II schematic and the corresponding section in
CalLite are shown in Figure 45 through Figure 53 (at the end of this appendix). CalLite's hydrologic
inputs were prepared by mapping CalSim II hydrology to the CalLite schematic as shown in these
figures and described in the rest of this appendix.
The major CVP/SWP reservoirs of the Central Valley (Shasta, Trinity, Whiskeytown, Oroville, Folsom,
and San Luis) are simulated in CalLite exactly as they are in CalSim II. Nodes on the CalLite schematic
generally correspond to important controlling locations on the CalSim II schematic (e.g. locations
where minimum flow requirements are enforced). CalSim II hydrology between those identified
points was aggregated to match the CalLite nodes. Diversions pertinent to a segment in CalSim II are
simulated as diversions from the relevant CalLite node. CVP/SWP project demands are simulated
dynamically in CalLite, whereas non-project demands are included as "pre-operated" timeseries that
are derived from a companion CalSim II study. For project deliveries, CalLite simulates the same
detailed deliveries as CalSim II (listed in Table 16, Table 25, Table 26 and Table 27), but then
aggregates them together to get the CalLite deliveries shown in the schematic.
CalSim II inflows, system losses/gains such as groundwater-surface water interaction, and return
flows are combined to create the “local inflow” at each CalLite node. Figure 45 through Figure 53
show exactly which area of the CalSim II schematic corresponds to each CalLite node. CalSim II
inputs and outputs are used to generate the net accretion/depletion within each of these areas,
which is identified as the “local inflow” to the corresponding CalLite node. If the net flows
contributing to a node result in a net depletion rather than accretion, then the “local inflow” may
have a negative value. In the CalLite schematic and in the tables below, these accretion/depletion
(AD) terms derived from CalSim II model outputs begin with the prefix "AD_". These terms make
CalLite results as consistent as possible with CalSim II results by adjusting for differences in
schematic detail between the two models.

CALLITE DOCUMENTATION VERSION 3.00
A.1.2
Shortages in North of Delta Accretion/Depletion Terms
Under certain scenario assumptions, when reservoir releases are very low, CalLite is not able to
generate a feasible solution which fully meets both the AD terms and the fixed non-project
deliveries north of the Delta. In order to avoid this problem, CalLite will allow the AD terms to be
"shorted", essentially adding more water to the system if that is the only way to generate a feasible
solution. This is done by employing soft constraints which use very high penalties (negative weights)
to strongly encourage AD terms to be fully met, but which will allow those terms to be shorted in
the circumstances described above. Table 7 shows the 10 nodes where the AD terms can be
shorted. If any of these terms have been shorted, CalLite will give a warning message at the end of
the simulation and users can examine detailed shortage data (i.e. water volumes) on the Quick
Results dashboard in the CalLite GUI.

A.2 Modeled Level of Development
The hydrology input datasets used by CalLite Version 3.00 have been developed using the CalSim II
2005 and 2020 LOD hydrology from the Common Assumptions Common Model Package (Version
9B) (DWR 2009). CalSim II model outputs are also used for generating AD terms. The CalSim II study
used for these outputs varies depending not only on LOD but also on whether the user selects a
Biological Opinion (BO) or pre-BO or D-1485 run basis (available on the Run Settings dashboard). For
a BO run basis the CalSim II study used is the one developed for analysis of the Bay Delta
Conservation Plan, as of April 2010. The pre-BO run basis study has identical assumptions except
that the BO Reasonable and Prudent Alternatives (RPAs) have been removed from the model.
Appendix E lists all of the assumptions in these Calsim II studies. Input data for CalLite is prepared
using the CS2CL tool, which uses the WRIMS 2 engine and WRESL code to convert CalSim II inputs
and outputs (DV and SV DSS files) into CalLite inputs. See Section 3.2 and Appendix H for description
of the CS2CL tool. If the user wishes to create CalLite inputs using CalSim II studies with different
assumptions than those described here, the CS2CL tool can be used to do this.

A.3 Rim Basin Inflows
Rim basin inflows to CalLite are shown in Table 8, along with the CalSim II flow record used for each
inflow. Inflows to north of Delta reservoirs are set equal to the equivalent CalSim II inflows as stored
in the SV DSS file. Inflows to the Delta from Eastside streams, the San Joaquin River, and the
Calaveras River are set equal to equivalent CalSim II output flows. Inflow to the Mendota Pool from
James Bypass, Millerton Flood control releases, and agricultural return flows are set equal to CalSim
II output. Inflow to the California Aqueduct from the Kern River is the same as CalSim II input flow.

A.4 Local Inflows
Local inflows are also generated from the appropriate CalSim II study. As described earlier, each
CalLite node corresponds to a section in the CalSim II schematic, and the local inflow at each CalLite
node is equal to the sum of CalSim II inflows and outflows to that section. Any diversions that are
dynamically determined (as opposed to pre-operated) in CalLite (e.g., CVP and SWP deliveries and
Fremont and Sacramento weir spills) are removed from the local inflows. The following figures and
tables illustrate CalLite hydrology development reach by reach.
A.4.1
Upper Sacramento River
The Upper Sacramento River representation in CalLite is illustrated in Figure 45 and the local inflow
calculations are provided in Table 9. The Upper Sacramento River representation includes Trinity,
Shasta, and Whiskeytown reservoirs and Lewiston Lake, Keswick Dam, and Red Bluff Diversion Dam
4
CALLITE DOCUMENTATION VERSION 3.00
(RBDD) as nodes. Lewiston Lake is simulated as a node on the Trinity River. The node is connected to
Whiskeytown Lake via Clear Creek Tunnel. Whiskeytown Lake is connected to the downstream node
(Red Bluff) through Clear Creek and to the Keswick Reservoir through Spring Creek Tunnel. Trinity
River exports are transferred to Keswick Reservoir through these two tunnels. The next node
downstream is the Red Bluff node, since it is the diversion point of the Tehama-Colusa Canal (TCC)
and the Corning Canal.
This CalLite node corresponds to a section in the CalSim schematic that extends from downstream of
Whiskeytown Lake and Keswick Dam (C3 and C5 arcs in CalSim II) to the RBDD (node 112). The
corresponding CalSim schematic area also includes the TCC and Corning Canal so that all demands
are lumped at the Red Bluff node in CalLite.

A.4.1.1 Keswick
AD_Kswck = C5-D3-C4. This AD term is calculated from a mass balance of inflows (release from
Shasta Dam, inflow from Spring Creek Tunnel) and outflows (release from Keswick Dam). CalLite
does not dynamically simulate storage and evaporation at Keswick Reservoir. CalSim II typically
maintains storage at a constant level of 23.80 TAF. CalSim II storage may drop to 16.30 TAF (Level 3)
or 0.01 TAF (Level 1) during critical periods.
A.4.1.2 Red Bluff
AD_RedBlf = C112-C5-C3+D104+D112. This AD term is calculated from a mass balance along the
Sacramento River from Keswick Dam (node 5) to Red Bluff Diversion Dam (node 112). CalLite
dynamically simulates CVP diversions to both settlement contractors and water service contractors
and explicitly represents non-project diversions from tributaries to the Sacramento River
(D104_NP); all other flow components are pre-processed based on CalSim II input or output and
folded into the CalLite AD term. These pre-processed flows include: (i) stream losses to groundwater
(GS60); (ii) tributary inflows including Cow Creek, Battle Creek, Cottonwood Creek and Paynes
Creek; (iii) return flows from agricultural and urban return flows. D_RedBlf consists of both project
and non-project components. The non-project component (D_RedBlfNP) is pre-processed using
CalSim II arc D104_NP.

Colusa Basin
Wilkins Slough was selected as the controlling node since it has the Navigation Control Point
minimum instream flow requirement and it is a suitable location to lump Colusa Basin demands. As
seen in Figure 46, the corresponding CalSim II schematic area includes all of the Glenn-Colusa Canal
(GCC) Irrigation District demands. Moulton, Colusa, and Tisdale are within that area but are not
modeled explicitly in CalLite, instead they are part of the AD term. Table 10 represents the local
inflow calculations within the Colusa Basin representation in CalLite.

AD_Wilkns = C129-C112+D113A+D113B+D114+D122A+D122B+D128+D129A. This AD term is
calculated from a mass balance along the Sacramento River from the Red Bluff Diversion Dam (node
112) to Wilkins Slough (which is used to represent the Navigation Control Point). CalLite dynamically
simulates CVP diversions to settlement contractors along this reach; all other flow components are
pre-processed based on CalSim II input or output. These pre-processed flows include: (i) stream
losses to groundwater (GS63); (ii) tributary inflows including Mill Creek, Deer Creek, Big Chico Creek,
Elder Creek, Thomes Creek and Stony Creek; and (iii) return flows from agricultural and urban return
flows; (iv) weir spills to the Butte basin (D117) and Sutter basin (D124, D125, D126).
D_Wilkns includes both project and non-project components. The non-project component
(D_WilkinsNP) is pre-processed using CalSim II arcs D113A and D113B. These represent Sacramento
River diversions; non-project diversions from tributaries to the Sacramento River are included in the
AD term (AD_Wilkns).
CalLite does not simulate storage regulation and diversions from Stony Creek. The net inflow to the
Sacramento River is part of the AD term (AD_Wilkns). Diversions from Stony Creek into the TehamaColusa Canal are also lumped into the AD term, and these diversions are considered when
calculating demand for Sacramento River diversions.

CALLITE DOCUMENTATION VERSION 3.00
Pre-processing of Colusa Basin Drain inflows make it unnecessary for CalLite to dynamically simulate
drain diversions through Knights Landing Ridge Cut during high flow conditions in the Sacramento
River.
A.4.3
Lower Sacramento River
The lower Sacramento River representation includes the Sacramento River- Feather River and
Sacramento River – American River confluences as well as the Yolo Bypass. The Fremont and
Sacramento Weirs are simulated dynamically and spill water to the Yolo Bypass depending on river
flows and rating curves as in CalSim II. Figure 47 illustrates the Lower Sacramento River
representation and Table 11 represents related local inflow calculations.

A.4.3.1 Confluence of the Sacramento and Feather Rivers
AD_SacFea = C160-C129-C223+D160. This AD term is calculated from a mass balance along the
Sacramento River from Wilkins Slough to the confluence with the Feather River. This AD term
includes inflow from the Colusa Basin Drain (C184A), irrigation return flows from RD108 and River
Garden Farms (R134), flood flows returning to the river via the Sutter Bypass, irrigation return flows
from the Sutter Basin returning to the river via RD 1500, inflow from Butte Creek via the Sutter
Bypass; and flows from managed wetlands in the Butte and Sutter sinks.
A.4.3.2 Confluence of the Sacramento and American Rivers
AD_SacAme = C169-C160-C303+D166A+D162+D163_PRJ+D165+D167. This AD term is calculated
from a mass balance along the Sacramento River from Fremont Weir/Feather River confluence
(node 160) and Freeport (node 169). This AD term includes: (i) depletions in Yolo and Solano
counties (D163_gain); (ii) agricultural and urban return flows (R169); (iii) water diverted from the
Bear River that is not depleted through irrigation. The formula does not include D168 (diversions at
Freeport) since those are not modeled dynamically.

CALLITE DOCUMENTATION VERSION 3.00
A.4.3.3 Yolo Bypass
AD_YoloBP = C156. This AD term represents the inflow to the Delta from the Yolo Bypass, excluding
the Fremont and Sacramento weir spills that are represented explicitly in CalLite. The AD term
includes net inflows from Cache Creek and Putah Creek, and agricultural and urban return flows. It
also includes flows diverted from the Colusa Basin through the Knights Landing Ridge Cut that are
not subsequently depleted for irrigation.
A.4.4
Feather River
The Feather River representation in CalSim II is scaled down to four nodes in CaLite: Lake Oroville,
Thermalito Complex, Feather River – Yuba River confluence and Feather River – Sacramento River
confluence. The minimum instream flow requirement below Thermalito is applied at both
Thermalito and Feather River - Yuba River confluence. Figure 48 and Table 12 summarize the

AD_Therm = C203-C6+D201+D202+D7A+D7B. This AD term is calculated from a mass balance on
the Power Canal, Thermalito Forebay and Afterbay and the Feather River low flow channel. This AD
term includes: (i) return flow from the Kelly Ridge powerhouse; (ii) effects of storage regulation and
evaporation in the Thermalito Afterbay. CalLite does not dynamically simulate storage and
evaporation at in the Afterbay. CalSim II typically maintains storage at a constant level of 55.00 TAF.
CalSim II storage may drop to 30.00 TAF (Level 2), or 15.10 (Level 1) during critical periods.
A.4.4.2 Confluence of the Yuba and Feather Rivers
AD_YubFea = C223-C203-C230+D204+D206A+D206B+D206C+D207A. This AD term is calculated
from a mass balance along the Feather River from Thermalito Afterbay release to the river’s mouth
near Verona. It includes inflow from the Bear River (C282), but not those from the Yuba River. The
AD term also includes stream losses to groundwater (GS65). All diversions from the Feather River
are treated as project diversions in CalLite and are modeled dynamically.

the diversions to the cities of Folsom and Roseville, San Juan Water District and El Dorado Irrigation
District. In CalSim II these diversions are represented by arc D8_NP.

A.4.6.2 Nimbus
AD_Nimbus = C9-C8+D9. This AD term is calculated from a mass balance of inflows (release from
Folsom Dam) and outflows (release from Nimbus Dam, diversion to Folsom South Canal). CalLite
does not dynamically simulate storage and evaporation at Lake Natoma. CalSim II typically maintains
storage at a constant level of 8.80 TAF. CalSim II storage may drop to 6.50 TAF (Level 3) or 1.75 TAF
(Level 1) during critical periods. Diversions at Nimbus represent deliveries via the Folsom South
Canal. These include deliveries to the Golden State Water Company, California Parks and Recreation,
SMUD (Rancho Seco Power Plant), and several agricultural districts in southern Sacramento County
(Omuchumne-Hartnell Water District, Galt Irrigation District, and Clay Water District).
A.4.6.3 H Street
AD_HSt = C303-C9+D302. This AD term represents stream losses to groundwater (GS66) and storm
runoff to the lower American River downstream of Nimbus Dam (I302). The diversion at HSt
(D_HStNP) represents diversions by the City of Sacramento at its Fairburn plant and by Carmichael
Water District for its Bajamont water treatment plant. These diversions are pre-processed in CalLite.
Diversions by the City of Sacramento are limited according to the Water Forum Agreement.
A.4.7
The Sacramento - San Joaquin River Delta
CalLite’s representation of the Delta retains the same level of detail present in CalSim II. Some nodes
represent specific places in the Delta while others represent general areas into which the Delta's
consumptive use was subdivided. Nodes are included for Hood, Delta Cross Channel, Sacramento
River at North Delta, Brannan Island, and Rio Vista, Mokelumne, Terminous, San Joaquin River at
Vernalis, Calaveras, Stockton, Central Delta, Medford Island, and Venice Island, Sacramento and SJR
confluence, West Delta, Rock Slough, Coney Island, Jones Pumping Plant, and Banks Pumping Plant
(see Figure 51). D-1641 specifies minimum instream flow requirements at Rio Vista and for Delta
outflow, and the FWS and NMFS Biological Opinions specify minimum instream flow requirements
for Old and Middle Rivers. Table 15 shows the local inflow calculations within the Delta.

South of Delta Export Area
Figure 52 and Figure 53 contain the CalLite schematic for the CVP and SWP south of Delta export
area. The Delta Mendota Canal starts at Jones Pumping Plant in the Delta and flows south to O’Neill
Forebay and San Luis Reservoir. From there, it continues to the Mendota Pool. The California
Aqueduct begins at Banks Pumping Plant and flows south to O’Neill Forebay and San Luis Reservoir
and continues to the southern San Joaquin Valley and Southern California. The canals in the CalLite
schematic are divided into sections based on canal capacity constraints relative to specific points of
diversion. San Luis Reservoir is dynamically operated within CalLite. Storage diversions and releases
at the SWP terminal reservoirs (Del Valle, Silverwood, Perris, Pyramid, and Castaic) are preprocessed by CalSim II and input into CalLite as diversion and inflow arcs. The diversions and local
inflows in the south of Delta export area are listed in Table 16.

A.5 Demands - North of Delta
North of Delta project demands are also based on 2005 and 2020 LOD CalSim II hydrology from the
Common Assumptions Common Model Package (Version 9B) (DWR 2009). Consistent with the
CalSim II approach, deliveries are constrained by CVP and SWP allocations and by land use-based
diversion requirements for the hydrologic planning area. Table 25 shows CalLite north of Delta
model nodes, corresponding Calsim II demand arcs, and CalSim II contract demand timeseries used
to represent project demands at each node. Table 25 also shows the DSA land use-based diversion
requirement associated with each demand timeseries.

A.6 Demands - South of Delta
A.6.1
State Water Project Demands
Twenty-nine agencies have contracts for a long-term water supply from the SWP totaling
approximately 4.2 million acre-feet (MAF) annually, of which about 4.1 MAF are for contracting
agencies with service areas south of the Delta. About 70 percent of this amount is the contract
entitlement for urban users and the remaining 30 percent for agricultural users. Implementation of
these demands in CalLite is similar to CalSim II, however, the contractors are grouped into three
types: agricultural (Ag), Metropolitan Water District’s municipal and industrial demands (MWD),
and other municipal and industrial demands (MI) (see Table 26); similar to older versions of the
CalSim II model.

Appendix B Future Water
Management Actions
B.1 Shasta Enlargement
Version 3.00 of CalLite includes the option to model the enlargement of Shasta Lake. The primary
objectives of the alternatives identified in the Shasta Lake Water Resources Investigation (SLWRI)
are (1) to increase survival of anadromous fish populations in the Sacramento River primarily
upstream from the Red Bluff Diversion Dam, and (2) to increase water supplies and water supply
reliability for agricultural, municipal and industrial, and environmental purposes to help meet future
water demands, with a focus on enlarging Shasta Dam and Reservoir.
For the purposes of the screening model implementation, three Shasta Dam enlargement
alternative dam raises of 6.5-feet (256 TAF), 12.5-feet (443 TAF), and 18.5-feet (634 TAF) are
considered. These are the three raise sizes analyzed in the SLWRI Draft Feasibility Report and
Preliminary Draft EIS released in February 2012 (Reclamation 2012), though the modeling in those
reports included specialized operations for M&I water supply that are not in CalLite.
With the exception of the specialized M&I water supply operation, implementation of the three
raise options in CalLite is identical to the CalSim II model, with an additional storage element added
to the model to represent the enlarged part of Shasta Reservoir. Flood control space in Shasta does
not change when Shasta is enlarged, hence the increased space is treated as additional conservation
pool. Trinity Reservoir operations are held constant for the three raises, by adjusting the balancing
logic used to trigger imports from Trinity into the Sacramento Basin.
The Shasta enlargement options are considered a component of the CVP, and increased Shasta
storage is directly integrated into COA, water supply indices, and operational decisions, etc. It is
recommended that if enlarged Shasta is activated in the model, the WSI-DI curves be recalculated to
take into account the impacts of enlarging Shasta on CVP (and SWP) water supply and operations.
B.2 Los Vaqueros Enlargement
The Los Vaqueros Expansion Model was developed to run planning and operations simulations of
key Contra Costa Water District facilities. Those facilities include Delta intakes at Rock Slough, Old
River, and Middle River (Victoria Canal), Los Vaqueros Reservoir, Old River Pipeline, the Transfer
Facility and Transfer Pipeline, Los Vaqueros Pipeline, and the Contra Costa Canal. Los Vaqueros
Reservoir was built and expanded to reduce the salinity of water delivered to the CCWD service
area. This is done by filling Los Vaqueros when there is low salinity at the Old and Middle River
intakes and releasing water for blending when Delta salinity is high.
There are proposals to expand Los Vaqueros beyond its current 160 TAF capacity. The CalLite user is
allowed to test different Los Vaqueros storage capacities to see how the system responds.
Increased capacity will result in increased Delta diversions when salinity is low and reduced Delta
37
CALLITE DOCUMENTATION VERSION 3.00
diversions when salinity is high. This can effect CVP and SWP export operations if there are changes
at Old and Middle River intake diversions when Old and Middle River flow criteria are controlling
exports. Changes in storage capacity can also affect diversions of CCWD CVP contract supply.

Appendix C Simulation of Delta
Regulatory Requirements
Unless otherwise noted, the water year types discussed in the following sections are based on the D1641 Sacramento River 40-30-30 Index (SWRCB 1995).
•
•
•
•
•
•
W = Wet
AN = Above Normal
BN = Below Normal
D = Dry
C = Critical
Subnormal Snowmelt = whenever the forecast of April through July unimpaired runoff is less
than 5.9 MAF during an otherwise wet, above normal, or below normal year.
This appendix describes the implementation of Delta regulatory controls in CalLite. The regulatory
controls in CalLite allow users to specify requirements for interior Delta flows, minimum river flows,
Delta outflows, export restrictions, and salinity objectives. The regulatory requirements modeled in
CalLite Version 3.00 are based on D-1485, D-1641, the 2008 FWS BO RPA, the 2009 NMFS BO RPA,
and other agreements relating to operation of the CVP and SWP. Figure 54 shows a map of the Delta
with the locations of Delta regulatory controls (see Section 7.4).
Figure 54. Delta regulatory control locations.
39
CALLITE DOCUMENTATION VERSION 3.00
The methodology used in the implementation of Delta regulatory controls is identical to that used in
the CalSim II model. However, in CalLite Version 3.00, the user can switch certain D-1485, D-1641,
and BO RPA regulations on or off, enter user-defined values for some D-1485 and D-1641
requirements, and also add other user-defined regulations. These user selections are specified
through dashboards in the GUI as shown in Figure 55, Figure 56, and Figure 58. If the user-defined
button is selected for a D-1485, D-1641 or other regulation, a unique table is activated to enable
custom inputs for the appropriate criteria.
The sections that follow describe the main Delta regulatory controls, assumptions, and method of
implementation. The main controls are:

C.1 River Flows
C.1.1
Sacramento River at Rio Vista Minimum Flow
The minimum flow in the Sacramento River at Rio Vista is specified by month and water year type.
The D-1485 standards include minimum flow requirements at Rio Vista throughout the whole year
(see Table 29), while the D-1641 standards only have requirements Sep-Nov (see Table 28). While
there are more D-1485 Rio Vista requirements throughout the year, the standards in Sep-Nov are
typically lower than those of D-1641.
If incidental flow is insufficient to meet the requirement, additional flow is provided through
releases from CVP and SWP reservoirs. Calculations of additional releases account for upstream loss
of water through the Delta Cross Channel and Georgianna Slough, depending on Delta Cross
Channel gate position.

For D-1641, the 7-day running average shall not be less than 1,000 below the monthly objective.
Table 29. D-1485 requirements for Sacramento River at Rio Vista (cfs).
In CalLite, the D-1485 Rio Vista requirement in March is assumed to be the average of the two
surrounding standards. Thus the March D-1485 minimum flow requirements at Rio Vista are actually
modeled in CalLite as shown in Table 30.

San Joaquin River at Vernalis Minimum Flow
Version 3.00 of CalLite has an option for using either a fixed or dynamic representation of San
Joaquin River operations. If the fixed option is chosen, the San Joaquin River flow at Vernalis is an
input timeseries derived from CalSim II model results, which include the effects of D-1641 Vernalis
minimum flow requirements. The dynamic option allows user selection or variation of the Vernalis
Minimum Flow.
C.2 Delta Outflow
Calculation of total required Delta outflow considers the NDO flow requirement (D-1641 and D1485) and the X2 required outflows (D-1641 only) described below.

Minimum Net Delta Outflow (NDO)
Under D-1641 standards, the minimum net Delta outflow is specified by month and water year type

3) 10,000 cfs during Feb-May of Wet years, 10,000 cfs during Feb-Apr of Subnormal Snowmelt
years for Suisun Marsh.
46
CALLITE DOCUMENTATION VERSION 3.00
4) 12,000 cfs for 60 consecutive days during Jan-Apr of Above Normal or Below Normal years
for Suisun Marsh.
5) 6,600 cfs during Jan-May when storage is at or above the minimum flood control level at
two out of three of: Shasta, Oroville, and CVP storage on the American.
Unlike D1641, D1485 does not include an X2 requirement. In CalLite, the partial month standards for
minimum Delta outflow are handled in the mrdo-final.wresl file, which calculates an overall Delta
outflow necessary to meet all of the standards. In August-December and sometimes in JanuaryMarch (whenever the 12,000 cfs or 6,600 cfs Suisun Marsh requirements do not apply) a minimum
monthly delta outflow requirement of 2,500 cfs is assumed in CalLite. The 12,000 cfs Suisun Marsh
requirement for 60 consecutive days is represented in CalLite by checking January’s Net Delta
Outflow Index 7 (NDOI) level when the model timestep is in February. If January’s (the previous
month’s) NDOI was above 12,000 cfs, the model forces the required Delta outflow in February to be
12,000 cfs (thus fulfilling the 60 day requirement). If NDOI is not above 12,000 cfs in January, the
model checks NDOI in February and repeats the logic. If NDOI is not above 12,000 cfs in January or
February, the model will require delta outflow during March and April to be above 12,000 cfs
If incidental flow is insufficient to meet the requirement, additional flow is provided through
releases from CVP and SWP reservoirs.
C.2.2
X2 Requirements
X2 is the location of the 2 parts per thousand salinity contour (isohaline), one meter off the bottom
of the estuary, as measured in kilometers upstream from the Golden Gate Bridge. In D-1641, an
electrical conductivity (EC) value of 2.64 mmhos/cm is used to represent the X2 location. In CalLite
the X2 position is estimated using an Artificial Neural Network (ANN) Dynamic Link Library. The ANN
is briefly described in Appendix F.2.
There is no X2 requirement under a D-1485 regulatory environment.
The D-1641 X2 standard is specified in terms of the number of days in a given month X2 has to be
located at or west of a particular compliance location. There are three possible compliance
locations: Collinsville, Chipps Island, and Roe Island. Each day the requirement may be satisfied any
of three ways: 1) the daily salinity at the compliance location is at or less than 2.64 mmhos/cm; 2)
The 14 day running average at the compliance location is at or less than 2.64 mmhos/cm; or 3) The
daily Net Delta Outflow Index equals or exceeds the compliance location's maximum flow effort
threshold (Collinsville = 7,100 cfs; Chipps Island = 11,400 cfs; Roe Island = 29,200 cfs). In each month
from Feb-June the X2 standard has to be met for a specified number of days at each of the three
compliance locations, as described below.
At Collinsville, X2 compliance is required February through June for the entire month. The only
exception to this is that if the Sacramento River Index (SRI) is less than 8.1 MAF (90% exceedance),
7 NDOI is defined in D-1641 regulations.
47
CALLITE DOCUMENTATION VERSION 3.00
the Collinsville standard does not apply in May and June and the minimum 14 day running average
of 4,000 cfs is used instead. The SRI is the sum of the unimpaired forecasted flow for: 1) Sacramento
River at Bend Bridge; 2) Feather River at Lake Oroville; 3) Yuba River at Smartsville; and 4) American
River at Folsom Lake.
At Chipps Island, X2 compliance is required for at least the number of days shown in Table 33. The
required days are linearly interpolated between the values shown in the table. The same 90%
exceedance exception for Collinsville applies here as well. Obviously, a day of X2 compliance at
Chipps would simultaneously satisfy the Collinsville X2 requirement.

When triggered at Roe Island (Port Chicago), X2 compliance is required for at least the
number of days shown in
Table 34. This requirement is “triggered” if the 14-day running average EC at Roe Island is less than
or equal to 2.64 mmhos/cm on the last day of the previous month. The required days are linearly
interpolated between the values shown in the table. The same 90% exceedance exception for

If the user wants to specify alternative X2 requirements, first it is necessary to select the months in
which the standard is to be active. Once these months are selected, the user enters desired monthly
average X2 position by month and water year type.
C.2.3
Trigger for Implementation of X2 Roe Island standard
This Roe Trigger is normally a part of D-1641 regulations. Under D-1641 standards, X2 is required to
be at or west of Roe Island for the number of days defined in Table 34 if the preceding month's X2
position is west of Roe. If the preceding month's X2 position was east of Roe, then the required
number of X2 compliance days for Roe is automatically set to 0. CalLite provides an option to include
or exclude this trigger. If the trigger is not used, then the required number of X2 compliance days for
Roe is always 0.
C.3 Interior Delta Flows
Regulations of the Interior Delta flows are handled on the “Others” regulation tab in CalLite.
C.3.1
San Joaquin River near Jersey Point (QWEST)
The San Joaquin River flow near Jersey Point, also known as QWEST, is often used as an indicator of
flow reversals in the lower San Joaquin River. While there is no current regulatory standard for
QWEST, some (e.g. NMFS 1993) have proposed minimum flow requirements based on QWEST to
sustain transport flows in the westward direction.
In CalLite there is a user-defined standard for QWEST flow that can be activated. The standard is
specified by month and water year type.
C.3.2
Old and Middle River combined flow (OMR)
Combined Old and Middle River flows restrictions are proposed as a means for reducing flow
reversals in these channels and limiting entrainment of Delta smelt and anadromous fish at the SWP
and CVP export facilities.
CalLite approximates the OMR flows by using a regression equation (see below) developed by
Hutton (2008), which has been calibrated to historical flow conditions as well as a full range of
hydrodynamic simulation results from the Delta Simulation Model II (DSM2) model. This equation
relates OMR flow to south Delta diversions (including some of CCWD diversions and local Delta
Island channel depletions) and the flow in the San Joaquin River at Vernalis. The equation includes
differing coefficients depending on Vernalis flow, head of Old River barrier (HORB) operation, and
Grant Line Canal (GLC) barrier operation as shown below. This equation is reported to be the most
accurate of existing equations designed for this purpose, but no independent analysis has been
performed.

OMR restrictions in CalLite are applied by preventing flow from being less (more negative) than a
defined standard, and are also translated into a maximum export restriction which allows for the
proper OMR flows. Allowable pumping when the OMR requirement is governing export operations
is currently shared equally between the SWP and CVP. Logic attempting to reflect USFWS' Dec 2008
OCAP BO RPA Actions 1, 2, and 3 for OMR was developed for CalSim II by a multi-agency group in
2009, and CalLite uses this same logic for applying OMR flow restrictions. The specifics of the OMR
RPA standard are described in a later section of this appendix on BO RPA actions. CalLite also has a
user-defined OMR option that specifies minimum allowable OMR values by month and water year
type.
C.4 Delta Cross Channel (DCC)
Operation of the Delta Cross Channel assists in transferring fresh water from the Sacramento River
across the Delta (DWR 1993). Flow from the Sacramento River into the DCC is controlled by two
radial arm gates located at the Sacramento River end of the DCC. These gates can be opened and
closed depending on water quality, flood protection, recreation, and fish protection requirements.
Historically during periods of high salinity the DCC gates have been opened, and during periods of
low salinity the DCC gates have been closed. See Table 36 for the monthly DCC gate closures as
implemented in CalLite under a D-1641 or a D-1485 scenario.

D-1485 Regulation
Under D-1485 regulation, there are two requirements for closure of the delta cross channel gates.
The first is to minimize diversions of young striped bass into the Central Delta and requires closure
of the gates for up to 20 days between April 16th and May 31st when the daily Delta outflow index is
greater than 12,000 cfs. In CalLite, the Delta outflow index for use in D-1485 scenarios is calculated
slightly differently, it is represented as the Net Delta Outflow Index (NDOI) 8. This striped bass
requirement also states that the gates should not be closed for more than two out of four
consecutive days, but this is not implemented in CalLite since it is a monthly timestep model.
The second D-1485 cross channel gate requirement is for closure of the gates anytime daily Delta
ouflow index is greater than 12,000 cfs between Jan 1st and April 16th. This standard minimizes cross
Delta movement of Salmon.
8 NDOI is defined in D-1641 regulations.
52
CALLITE DOCUMENTATION VERSION 3.00
To implement these two April cross channel gate standards in CalLite, it is assumed that the gates
are closed for 21 days total during this month: six days to meet the striped bass requirement and an
additional 15 days to meet the salmon requirement. The other 14 days needed to meet the striped
bass requirement are made up in May.
The D1485 model is also run with a flood flow requirement that will close the gates if C_Hood is
greater than 25,000 cfs. To handle both the 12,000 cfs delta outflow requirement and the 25,000
cfs flood flow requirement, it is assumed in the first model cycle that the gates are open in all
months. By the second cycle, however, the model is able to accurately predict a flood flow and so
the cross channel gate closure is also accurate.
A few checks were completed to ensure that the model closes the cross channel gates as required
by the D-1485 standards. By the final cycle, the model performs exactly as expected given the D1485 standards and the flood flow requirement.
C.4.2
D-1641 Regulation
Under D-1641, the Cross Channel Gates may be closed for up to 45 days during the Nov – Jan period
for fishery protection. CalLite assumes a fixed schedule: 1) Nov, 10 days closed; 2) Dec, 15 days
closed; and 3) Jan, 20 days closed. The Cross Channel Gates are closed Feb – May 20, and closed for
14 days between May 21 – Jun 15. In addition, to prevent channel scour, the gates are closed
whenever Freeport flows are sustained above 25,000 CFS. CalLite also has an option to implement
NMFS' June 2009 OCAP BO RPA Action IV.1.2 for the DCC operation on top of the D-1641 standard.
This is described in a later section of this Appendix on BO RPAs. A user-defined option is also
available. Under D-1641, RPA, or user-defined operations, the number of days “open” are specified
and a fraction is computed internally depending on the number of days in the month.
The flows through the DCC and Georgianna Slough are estimated based on the regression equations
that relate DCC+GEO flow to upstream Sacramento River flow and gate position. These equations
are:
Qdcc+geo_open = 0.293*Qsac+2090 cfs (DCC gates open)
Qdcc+geo_closed = 0.133*Qsac+829 cfs (DCC gates closed)
The diversion from Sacramento River to the Central Delta is then calculated as:
Qdcc+geo_open*DCC_FractOpen+Qdcc+geo_closed*(1-DCC_FractOpen)
The DCC impact on salinity is considered in the Artificial Neural Network (ANN) flow-salinity
computations.
C.5 Export Restrictions
CalLite monthly exports are typically restricted according the following constraints: pumping and
conveyance restrictions, export-inflow (EI) ratio, VAMP period export limits, and salinity controls. In
addition, OMR restrictions (Section C.3.2) and BO RPA actions for Fall X2 (Section C.7.2) and the DCC
(Section C.7.4) are also translated into export constraints under certain conditions. Pumping
53
CALLITE DOCUMENTATION VERSION 3.00
restrictions (D-1485 and D-1641), the EI ratio (D-1641 only), and VAMP limits (D-1641 only) are
discussed below.
C.5.1
Pumping Restrictions
D-1485 places a 3,000 cfs export restriction in May and June for Jones and Banks pumping plants
and an additional restriction of 4,600 cfs in July for Banks (see Table 38).
Table 38. Jones and Banks monthly pumping limits under D-1485 and D-1641 standards.
Condition 3 of D-1485 allows the CVP to make up any deficiency caused by the May/June 3,000 cfs
restriction through coordinated operations with the SWP in later months (“payback wheeling”, see
Section 6.5.4.2). This may be achieved by either direct diversion or re-diversion of releases of stored
water through SWP facilities. The CalLite model handles this operation through the addition of
payback wheeling terms.
C.5.2
Export-Inflow Ratio
EI ratios limit the combined export rate of the SWP and CVP to a specified percentage of the total
Delta inflow. Under default D-1641 criteria, the February value is computed based on the January
Eight River Index, while all other months have a specific maximum EI ratio (see Table 39). If userdefined EI values are specified, all months have specific maximum ratios. If EI ratio limits total
project exports, the allowable export capacity is theoretically shared equally between the SWP and
CVP, although under the Coordinated Operations Agreement (COA), if one project cannot use its full
share due to operational limitations, the unused share can be used by the other party.

Export-San Joaquin River Inflow Ratio
A user-defined ratio of export to San Joaquin inflow is included in CalLite and works similarly to the
EI ratio described in the above section. This implementation relates the maximum allowable export
54
CALLITE DOCUMENTATION VERSION 3.00
to the San Joaquin River flow at Vernalis. The user has the ability to define this cap using a multiplier
and offset in the form:
Exports ≤ [A + (B * Q San Joaquin at Vernalis)]
Both coefficients A and B can vary by month and water year type, and are entered by the user in the
Regulations/Others dashboard. This criteria differs from the D-1641 EI ratio criteria not only in the
format (i.e. offset and multiplier vs. the specification of a ratio) but also in that this export cap has
no effect on increasing inflow to the Delta from the San Joaquin River, since these flows are not
controlled by COA.
NMFS' June 2009 OCAP BO RPA Action IV.2.1 Phase II for the San Joaquin River is also available to
the user as an option for specifying export limits based on Vernalis flow. This is described later in
Appendix C.7.
C.5.4
Vernalis Adaptive Management Plan (VAMP) Export Limits
D-1641 restricts SWP and CVP exports during the Spring pulse window of April 15 – May 15 to a
combined rate of the maximum of 1500 cfs or 100% of the 3-day running average of the flow at
Vernalis. As with other export limits, the allowable export capacity is shared equally between the
SWP and CVP.
An additional Spring pulse period export cap is imposed on the CVP as a B2 action (§3406(b)(2) of
the Central Valley Project Improvement Act (CVPIA), which directs the CVP to dedicate up to 800
TAF of project yield to beneficial uses for fish, habitat, and other environmental purposes). This B2
Action 3 export cap on CVP pumping is 750 cfs when the VAMP flow target is 2000, 3200, or 4450
cfs; 1125 cfs when the flow target is 5700 cfs; and alternates between 750 and 1500 when the flow
target is 7000 cfs. The only exception is that when Vernalis flow is > 8600 cfs, the limit is the
maximum of Vernalis flow/2 and 3000 cfs. This same additional Spring pulse period export cap is
imposed on the SWP under operational assumptions adopted during testing of the Environmental
Water Account.
In certain situations, it is possible for the user to have the VAMP export cap turned on while the
VAMP pulse flows are turned off (either when using the dynamic San Joaquin module or when using
a D-1485 run basis, which has no VAMP pulse flows). In these cases the VAMP export cap will be deactivated, since that cap is based on the pulse flow requirement, so cannot be accurately set
without it. In these cases the D-1641 export cap will remain active.
VAMP export limits do not occur under a D-1485 regulatory environment, but there is the option in
CalLite to use D-1641 VAMP “on” hydrology with a D-1485 regulatory environment (to allow better
isolation of various criteria effects).
55
CALLITE DOCUMENTATION VERSION 3.00
C.6 Salinity
The salinity in the Delta is estimated in the CalLite model through implementation of the most
recent ANNs developed by DWR (1995). The ANNs receive inputs of boundary flows, DCC gates
position, exports, San Joaquin salinity, and tides to estimate salinity (electrical conductivity) at each
of these locations. Through a linkage to the external ANNs, the CalLite model can both simulate the
monthly and 14-day average salinity in the forward direction, and approximate the maximum
allowable export for a given maximum salinity in the reverse direction. The allowable export
capacity for SWP and CVP is shared per COA, since meeting salinity is an in-basin use under COA. The
CalLite model allows the user to turn on and off specific standards, but the ability to specify new
standards is not currently enabled.
D-1485 and D-1641 regulations lay out several standards (detailed below) to protect the following
beneficial uses: municipal and industrial, agriculture, and fish and wildlife. Note that the physical
standards are sometimes buffered (lowered) or ramped (preceded) when implemented in CalLite in
order to ensure compliance.
C.6.1
Municipal and Industrial Water Quality Standards
To protect municipal and industrial beneficial uses, D-1485 regulation sets maximum mean daily
chloride standards at five locations: Contra Costa Canal Intake (or at Antioch Water Works Intake on
the San Joaquin River), City of Vallejo Intake at Cache Slough, Clifton Court Forebay Intake at West
Canal, and Delta Mendota Canal at Tracy Pumping Plant. These requirements are identical to those
in D-1641 regulations, with the exception of an additional standard location (Barker Slough at North
Bay Aqueduct Intake) in D-1641. In CalLite, we only model the chloride standards at the Contra
Costa Canal Intake and this standard is applied at the Rock Slough junction.
C.6.1.1 Rock Slough
The D-1485/D-1641 requirements set two Chloride standards at Rock Slough. The first is a
maximum mean daily chloride level of 250 mg/L throughout the year. The second is a requirement
to keep mean daily Chloride levels under 150 mg/L for a certain amount of days per year, depending
on the water year type (see Table 40).
Table 40. Maximum allowable salinity at Rock Slough.
The Chloride standards at Rock Slough are modeled as shown in Table 41. Notice that a compliance
buffer is created in CalLite by using 225 mg/L and 130 mg/L as the maximum Chloride levels instead
of 250 mg/L and 150 mg/L, respectively. This buffer is necessary in CalLite because of uncertainty in
56
CALLITE DOCUMENTATION VERSION 3.00
ANN calculations. Also, ramping occurs on either ends of the 130 mg/L standard during some water
year types to prevent large jumps in the Chloride levels.
Table 41. Maximum Rock Slough salinity requirement as modeled in CalLite (in mg/L
Chloride).
C.6.2
Agriculture Water Quality Standards
The D-1485 and D-1641 requirements for protecting agriculture are identical. Both regulations place
requirements in the Western and Interior Delta at Emmaton, Jersey Point, Terminous, and San
Andreas Landing. The standards at Terminous and San Andreas Landing are not included in the
CalLite Model.
C.6.2.1 Emmaton
D-1485/D-1641 regulations place a maximum 14-day running average of mean daily electrical
conductivity (EC) at Emmaton on the Sacramento River. This standard is applied from April 1st to
August 15th during all year types (see Table 42).
Table 42. Maximum allowable salinity at Emmaton (in mmhos).
To implement these EC requirements in CalLite, the standards are modified slightly as shown below
in Table 43. The standard for June during Below Normal and Dry years is calculated from a dayweighted average of the May and July standards. The standards for August (for all years except
Critical) are also calculated from a day-weighted average by assuming that salinity is 2.25 mmhos for
August 15th-31st. This helps ensure that a large jump in salinity does not occur immediately after
relaxation of the standard. The August standard during a critical year is assumed to be continued
from the April-July requirement (2.78 mmhos). There is no EC standard for September-March.

CALLITE DOCUMENTATION VERSION 3.00
Table 43. Implementation of maximum Emmaton EC standards in CalLite (in mmhos).
C.6.2.2 Jersey Point
D-1485/D-1641 regulations place a maximum 14-day running average of mean daily EC at Jersey
Point on the San Joaquin River. This standard is applied from April 1st to August 15th during all year
types (see Table 44).
Table 44. Maximum allowable salinity at Jersey Point (in mmhos).
To implement these EC requirements in CalLite, the standards are modified slightly as shown below
in Table 45. The process is the same as that described above for Emmaton EC standards. The
standard for June during Below Normal and Dry years is calculated from a day-weighted average of
the May and July standards. The standards for August are also calculated from a day-weighted
average by assuming that salinity is 2.25 mmhos for August 15th-31st. This helps ensure that a large
jump in salinity does not occur immediately after relaxation of the standard. There is no EC
standard for September-March.
Table 45. Implementation of Jersey Point EC standards in CalLite (in mmhos).
58
CALLITE DOCUMENTATION VERSION 3.00
C.6.3
Fish and Wildlife Water Quality Standards
To protect water quality for fish and wildlife, D-1485/D-1641 regulations set maximum EC levels at
Prisoners Point, Antioch Waterworks Intake, Chipps Island, Collinsville, and several miscellaneous
locations near Suisun Marsh. Only the Salinity standards at Antioch (D-1485 only), Chipps Island (D1485 only), and Collinsville (D-1485 and D-1641) are modeled in CalLite.
C.6.3.1 Antioch Waterworks Intake
There are two D-1485 EC standards at Antioch Waterworks Intake on the San Joaquin River. Both
standards are for striped bass spawning. The first standard is a 1.5 mmhos maximum for the
average of mean daily EC from April 15th through May 1st. This is implemented in CalLite by
assuming the standard only exists for the full month of April. The second standard is a relaxation
provision that replaces the first Antioch standard whenever the projects impose deficiencies in firm
supplies. This second EC standard is in place during April 1st to May 5th and ranges from a maximum
of 1.5 mmhos to 25.2 mmhos (depending on total annual imposed deficiencies). This relaxation
provision is not implemented in the CalLite model.
C.6.3.2 Chipps Island
D-1485 regulations place a maximum 28-day running average of mean daily EC at Chipps Island in
Suisun Marsh. A maximum average EC of 12.5 mmhos is required October through May and an EC
of 15.6 mmhos is required October through December only when project water users are taking
deficiencies in scheduled water supplies and it is a Dry or Critical year. In CalLite, the 28-day running
average is implemented as a monthly standard. It is assumed that projects take deficiencies during
the 14 dry/critical years listed in Table 46.

Sacramento River to no exceed the values shown in Table 47. These monthly EC requirements are
modeled in CalLite exactly as shown in Table 47, but they are assumed to be average monthly
requirements (not average of both high tide values, as specified in D-1485/D-1641 regulation).
There is no EC standard implemented in CalLite for June through September.

C.7 Biological Opinion Reasonable and Prudent Alternative
(BO RPA) Actions
The CalLite model uses the same implementations of the USFWS OCAP Smelt BO (FWS 2008) and
NMFS OCAP Salmon BO (NMFS 2009) actions that were developed for CalSim II. Switches built into
CalLite allow the user the option to turn each RPA on or off individually. The modeling logic is
described below – as with the CalSim II model, given the dynamic, real world data-conditioned
nature of the RPA actions and the relatively generalized representation of the RPA actions in the
model, much caution is required when interpreting outputs from the model.
C.7.1
Old and Middle River Flow Criteria (FWS RPA Actions 1-3)
Actions 1-3 of the FWS Smelt RPA specify limits on how negative the combined flows in Old and
Middle River (OMR) may be. As described in the earlier OMR section, limits on negative flow may
limit exports at Jones (CVP) and Banks (SWP) pumping plants. The three actions generally follow one
another sequentially, potentially limiting exports in any month from December through June. The
actions are based on triggers for turbidity, salvage, temperature, and spawning. CalSim II uses
hydrologic conditions and historical air temperature as surrogates for determining turbidity and
temperature triggers. Specific standards vary from -1,250 to -5,000 cfs depending on which Action is
being implemented and other criteria described in the BO. OMR criteria are relaxed if necessary
such that any effective limit on combined Jones and Banks exports does not drop below 1,500 cfs,
for health and safety purposes.
The three OMR actions are not easily toggled on and off independently given the interdependent
manner in which they are specified in the Smelt BO, so the user can either turn them all on or all off
using the GUI. Because there is also a user-defined option for OMR flows which could conflict with
the RPA standard, if the user-defined option is activated, the RPA standard is automatically
deactivated even if its checkbox is on, and only the user-defined standard applies.
To be consistent with CalSim II, the smelt OMR actions are assumed to by and large cover similar
OMR actions contained in the NMFS Salmon BO.
60
CALLITE DOCUMENTATION VERSION 3.00
C.7.2
Fall X2 Requirements (FWS RPA Action 4)
This action requires the X2 position in each of the months of September and October to be no
farther east than 74km following wet water years and 81km following above normal water years. In
November, continued adherence to the Fall X2 target can require release of up to the total inflow to
CVP/SWP reservoirs in the Sacramento Basin. The action is modeled in CalLite in the same manner
as in CalSim II, as summarized in Table 48 below. If reservoir releases are not sufficient to meet the
X2 requirement in September and October, exports may also be restricted, though never below
1,500 cfs for health and safety reasons.
Table 48. Summary of FWS RPA Action 4 implementation.

Above Normal Years

September (last month of
Wet or Above Normal water
years) and October (first

nd

continue to meet monthly average X2 requirement (74 km in Wet
years, 81 km in Above Normal years)
Note: The description in this table refers to the Oct-Sept water year, as used in CalSim/CalLite
computations.
This action can be turned on or off in CalLite using the GUI. Both D-1641 and RPA X2 standards can
be applied at the same time, since they apply in different months. But if the user has specified userdefined criteria for X2, then the RPA X2 standard is always turned off even if its checkbox is on, to
prevent confusion about which standard applies.
C.7.3
Clear Creek Flows (NMFS RPA Action 1.1.1)
This action calls for spring attraction flows to encourage fish to move upstream for spawning in
Clear Creek. Although the action specifies 2 pulse flows of 600 cfs for 3 days in each of the months
of May and June, as in the CalSim II model, CalLite implements the criteria by increasing required
Clear Creek flows by 600 cfs for 6 days all in the month of May. This approach accommodates the
underestimate of the actual flows that would occur subject to the daily operational constraints of
Whiskeytown Reservoir. The implementation of the RPA maintains the B2 stability criteria, which
seeks to prevent precipitous drops in flow from one month to the next.
C.7.4
Delta Cross Channel Gate Operation (NMFS RPA Action
4.1.2)
This action modifies the D-1641 DCC criteria, potentially decreasing the number of days that the
Delta Cross Channel gates may be open in October through January. The increase in the number of
days that the gates are closed is a function of the likelihood for flushing flows (> 7500 cfs) in the

Sacramento River, computed from flow at Wilkins Slough. Gate closure days are not increased if this
would result in the violation of D-1641 salinity standards at Rock Slough. During each additional day
that the DCC Gate would close under the RPA, but doesn't due to salinity considerations, combined
CVP and SWP exports are limited to 2000 cfs.
DCC operations under this RPA will always have no more days open than the D-1641 DCC standard,
and in some months the gates may be closed more frequently. Since this RPA was crafted as extra
protection above and beyond the D-1641 standard, it will operate identically whether or not the D1641 DCC standard is explicitly activated in the GUI. Because there is also a user-defined DCC
standard which could conflict with the RPA standard, if the user-defined option is activated, the RPA
standard is automatically de-activated even if its checkbox is on, and only the user-defined standard
applies.
C.7.5
San Joaquin River Inflow to Export Ratio (NMFS RPA
Action 4.2.1)
This action limits combined CVP and SWP exports relative to San Joaquin River flow at Vernalis as
described by the ratios in Table 49 below, based on the San Joaquin River 60-20-20 Index (SWRCB
1995), in April and May. The export limit cannot be less than 1500 cfs to be consistent with health
and safety provisions of project operations.

C.8 SWRCB Delta Flow Criteria
Senate Bill No. 1 (SB 1) contains the Sacramento-San Joaquin Delta Act, which requires the SWRCB
to use a public process to develop new flow criteria for the Delta ecosystem. In 2010 the SWRCB
issued a report on this topic (SWRCB 2010).
Major components of the Delta Flow Criteria included in the report require the flows for Delta
outflow, the Sacramento River at Rio Vista, and the San Joaquin River at Vernalis to be at or above
certain percentages of unimpaired flow. Table 50 shows these criteria, which are from the Delta
Flow Criteria CalSim II study Scenario A. In CalLite the user can compare the flow at these three
locations to the criteria. The user can also adjust the percent of unimpaired inflow used as the
criteria for each month. Note that unlike all of the other regulations described in this Appendix,
when this option is activated, CalLite does not force flows at these locations to meet these criteria. It
only compares simulated flows to the criteria and computes how much additional water would be
needed to meet the criteria, if it is not met.

Comparison between CalLite v3.00
and CalSim II
This appendix lists the assumptions in CalLite Version 3.00 and the comparable assumptions in the
CalSim II model. The CalLite assumptions listed below are for scenarios where SWRCB D-1641
standards and Biological Opinion Reasonable and Prudent Alternatives are turned on, and where
south of Delta demands are not user-defined. The version of the CalSim II model described here was
created for modeling related to the Bay Delta Conservation Plan (BDCP), as of April 2010. For
reference, the BDCP model used 2005 and 2020 LOD hydrology from the Common Assumptions
Common Model Package (Version 9B) (DWR 2009), but contains changes to the CalSim model code
since Version 9B was developed.

Appendix F
Sea Level Rise and
Climate Change Scenarios
Dynamic Link Libraries (DLL) have been developed and linked with CalLite for different sea level rise
options to estimate salinity (electrical conductivity) and X2 position. This Appendix describes
development of the DLL.
F.1 Background
F.1.1
Sea Level Rise Estimates
The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4)
released in 2007 contained the IPCC’s latest projections of future climate including revised estimates
of global mean sea level rise. The IPCC AR4 sea level rise estimates have been widely criticized for
their failure to include the dynamic instability in the ice sheets of Greenland and Antarctica, and for
their under-prediction of recent observed sea level increases (BDCP, 2012).
The CALFED Independent Science Board (ISB) recommends the empirical approach developed by
Rahmstorf (2007) that projects future sea level rise rates based on the degree of global warming.
This method better reproduces historical sea levels and generally produces larger estimates of sea
level rise than the IPCC AR4 projections (BDCP 2012). Rahmstorf projects a sea level rise from a low
range of 50-70 cm to a high range of 100-140 cm (depending on the range of uncertainty) by the end
of the century (2100). The BDCP analysis used Rahmstorf projections to estimate a 2025 sea level
rise of 12-18 cm (early long-term) and a 2060 sea level rise of 30-60 cm (late long-term). BDCP
proposes the mid-range of these estimates for each timeline (15 cm for the early long-term and 45
cm for the late long-term) because of the uncertainty in the projections (see Figure 59).
Figure 59. Location of BDCP sea level rise projections for Early Long-Term and Late
Long-Term, in relation to other scientific reports.
85
CALLITE DOCUMENTATION VERSION 3.00
CalLite implements three climate projection periods based on the BDCP analysis:
1. Historical Hydrology: Base 0 cm
2. Mid-Century (2030-2059): 15 cm
3. End-of-Century (2060-2099): 45 cm
The ANN for the Base 0 cm option was trained to reflect DSM2 representation of the BDCP No
Action Base scenario. The 15 cm and 45 cm options correspond to the average projected sea level
rises for 2025 and 2060, respectively, as selected for analysis in the BDCP study process.
F.1.2
Climate Change Scenarios
CalLite allows modeling of the five climate change scenarios (Q1-Q5, see Figure 60) used in the BDCP
analysis. These scenarios were determined by mapping 112 future climate projections (shown as the
small blue diamonds in Figure 60) used in the IPCC AR4 and obtained from 15 different Global
Climate Models developed by various national climate centers. In Figure 60, the blue dashed lines
are the median (50th percentile) change of annual temperature (horizontal line) and annual
precipitation (vertical line); these lines break the graph up into four quadrants representing (1) drier,
less warming, (2) drier, more warming, (3) wetter, more warming, and (4) wetter, less warming, with
respect to the median. The ten nearest neighbors (10NN) to the four intersections of the 10th and
90th percentile annual temperature and precipitation lines (red lines in Figure 60) were statistically
selected for defining climate change scenarios Q1-Q4. Scenario Q5 is bounded by the 25th and 75th
percentile joint temperature-precipitation change and represents a central region of climate change.

2013)

F.2 Development of Artificial Neural Networks
F.2.1
Salinity Estimation
Because of the projected sea level rise due to climate change, CalLite incorporates methods for
estimating Delta salinity under different sea level rise assumptions and corresponding tidal
boundary conditions. Artificial Neural Networks (ANN) (DWR 1995) were developed to estimate
flow-salinity relationships in the Delta for different sea level rise scenarios. These ANNs were trained
using results from the Delta Simulation Model II (DSM2). DSM2 is a hydrodynamic and water quality
model of the Delta, developed and maintained by DWR. The DSM2 model used for ANN training was
developed for simulating the Bay Delta Conservation Plan (BDCP 2011) and includes the marsh
restorations of the BDCP except for the base SLR. The ANNs are incorporated into CalLite to ensure
that project reservoirs and export facilities in the South Delta are operated to meet salinity
standards in the Delta.

period, sea level rise, and climate change scenario.
87
CALLITE DOCUMENTATION VERSION 3.00
F.2.2
X2 Estimation
Previous versions of CalLite had the option to use the Kimmerer-Monismith (KM) equation to
estimate the X2 location. However, the KM equation is empirical, developed using observed data,
and cannot be used for future sea level rise scenario analysis. Therefore version 3.00 of the CalLite
GUI no longer enables use of the KM equation. Advanced users may still enable the KM equation by
manually running the model with the WRIMS IDE or using the batch file (see Appendix I). The ANNs
discussed above are used to estimate X2 location for current sea level and future sea level rise
scenarios. The ANNs use Net Delta Outflow, previous X2 locations, and tides in the previous 117
days to predict the current X2 location.
F.3 Comparison between CalSim II and CalLite results
This section is provided from the CalLite Reference manual v2.00, released October 2011. While the
summary results have not been updated to match the model being released under version 3.00, the
relative comparison of results remains similar.
To verify the implementation of the newly developed ANN DLLs in CalLite, comparisons have been
performed on the results obtained from the CalSim II and CalLite models. Assumptions are Existing
Level of Developments (2005), Current Demands (2005), Existing Facilities and BO RPA regulations.
Figure 62, Figure 63, and Table 51 compare the results between CalSim II and CalLite for current
(base no sea level rise) scenario. The results indicate that CalSim II and CalLite results are very
similar.

Appendix G CalLite Allocation
Procedures
G.1 Introduction
Version 3.00 of CalLite implements delivery allocations for the CVP and SWP using either the Water
Supply Index-Delivery Index (WSI-DI) logic that is used in the CalSim II model (DWR 2002, DWR 2009
or the Forecast Allocation Method (FAM). The Operations dashboard allows selection of the
different allocations options (see Figure 64).
Figure 64. Operations dashboard in CalLite.
92
CALLITE DOCUMENTATION VERSION 3.00
G.2 WSI-DI Method
The default option for delivery allocations for the CVP and SWP in the current version of CalLite
incorporates the WSI-DI logic. The default CVP and SWP delivery logics use runoff forecast
information and uncertainty (associated exceedance probability), delivery versus carryover risk
curves, and standardized rules (Water Supply Index versus Demand Index Curve) to estimate the
total water available for delivery and carryover storage for CVP and SWP. Each project has a
separate WSI-DI process. The delivery logic updates delivery levels monthly from January through
May for SWP and from March through May for CVP as water supply parameters become more
certain.
During each water year, the model calculates a Water Supply Index (WSI) and determines what
portion of the WSI is available for use as delivery to contractors and carryover storage. WSI is
defined as the sum of the current beginning of month (BOM) storage in reservoirs that are able to
supply south of Delta diversions and the forecasted remaining water year runoff. The CVP WSI
components include the BOM storage in Trinity Lake, Shasta Lake, Folsom Lake, CVP-San Luis
Reservoir, and the remaining water year unimpaired runoff to Sacramento River, American River,
and James Bypass inflow. The SWP WSI components include the BOM storage in Oroville Lake and
SWP-San Luis Reservoir, and the remaining water year unimpaired runoff to Oroville Lake. Demands
are pre-processed, independent of the model. They vary according to the specified level of
development (2005, 2020) and according to hydrologic conditions. Demands serve as an upper
bound on deliveries. The Delivery Index (DI) that represents water available for delivery and
carryover storage is estimated as a function of the WSI value through a rule curve (WSI-DI table).
Once the total water available for delivery and carryover storage is estimated, it is split into target
delivery and estimated carryover storage by use of a delivery versus carryover risk curve (DeliveryCarryover curve). There are filling targets for San Luis Reservoir when water is transferred from
northern storage to San Luis reservoirs for later deliveries south of the Delta.
Separate WSI-DI curves are used for the SWP and CVP allocations. The north of Delta CVP allocations
are determined by using a system-wide CVP WSI-DI curve. Once the water available for use by the
CVP system-wide is estimated, it is split into target delivery and estimated carryover storage by use
of the Delivery-Carryover curve. CVP south of Delta allocations vary depending on whether active
regulations include BO RPA standards or not. Both approaches inform the allocation with estimates
of export capacity. For the without-RPA option, a Delta Index is computed as the sum of January-toMay Eight River Index values, and then an Export Index is created as a function of the Delta Index. A
second estimate of annual deliveries is also computed that takes into account VAMP export
restrictions that occur during the Apr 15 - May 15 pulse period, and also anticipates export
restrictions under CVPIA 3406(b)(2) that occur during the first half of Apr and the second half of May
and the entire month of June. The final CVP SOD allocation is the minimum of the Export Index and
this annual delivery estimate. The with-RPA option bases allocations on an annual estimate of
deliveries that takes into account the expected impact of the RPAs on exports. Currently the withRPA allocation option is automatically triggered when the FWS RPA for Old and Middle River is
active, as this RPA accounts for the majority of CVP export limits due to RPAs.
For the SWP, the south-of-Delta SWP contractors and project M&I contractors in the Feather River
Service Area (FRSA) deliveries are allocated using the WSI-DI procedure. SWP north of Delta
deliveries to FRSA agricultural contractors are not subjected to the WSI-DI allocation procedure. In
93
CALLITE DOCUMENTATION VERSION 3.00
drought years, FRSA agricultural contractors demands can be reduced no more than 50 percent in
any one year and no more than 100 percent in any series of seven consecutive years.
The WSI-DI curve and the Delivery-Carryover curve for CVP can be predetermined and imported
from CalSim II simulations or generated directly in CalLite. Similarly, the WSI-DI curve for SWP can
also be predetermined and imported from CalSim II simulations or generated directly in CalLite.
However, CalLite and CalSim II are no longer using a predetermined Delivery - Carryover curve for
SWP. CalLite and CalSim II both now compute the SWP target delivery using a predefined function.
This Delivery – Carryover function is defined by the independent variable “Demand Index” and 3
internal variables: 1) Oroville storage at the end of September, 2) SWP Table A allocation, 3) Table A
losses; and 3 fixed parameters: 1) a predefined DI buffer (250 TAF), 3) an initial SWP Drain Target of
110 TAF, and 3) the Oroville Lake storage level at 1067 TAF.
The WSI-DI curves should be edited with caution. They are carefully developed through iterative
running of CalSim II with a particular set of water supplies and demands. More aggressive
allocations may result in reservoir storage conditions that are not able to meet regulations through
dry years. Relaxed allocations may result in storage levels that create higher flows in some months
and unexpected modifications to Delta operations that are predicated on antecedent conditions.
Results will not always be what the user intended. Careful analysis of output is always necessary.
G.3 Forecast Allocation Method (FAM)
The Forecast Allocation Method (FAM) is developed based on the California Allocation Module
(CAM). The model is developed by utilizing the multi-step optimization functions in WRIMS 2. FAM is
coupled with CalLite model by working as an additional cycle.
FAM’s allocation process is shown in Figure 65. The FAM model can be used to allocate water for
both CVP and SWP and it can handle both existing and future hydrological conditions.

WRIMS 2 and using. With Multi-Step Optimization syntax in FAM, model is significantly simplified.
Code without using Multi-Step Optimization Syntax:
goal set_C30_Jan {C30_Jan + D30_Jan = C3_Jan + C2_Jan + I30_Jan}
goal set_C30_Feb {C30_Feb + D30_Feb = C3_Feb + C2_Feb + I30_Feb}
goal set_C30_Mar{C30_Mar + D30_Mar = C3_Mar + C2_Mar + I30_Mar}
…
goal set_C30_Nov {C30_Nov+ D30_Nov = C3_Nov + C2_Nov+ I30_Nov}
goal set_C30_Dec {C30_Dec + D30_Dec = C3_Dec + C2_Dec + I30_Dec}
Code using Multi-Step Optimization Syntax:
define FAM_Months {value 12}
goal(FAM_Months) set_C30 {C30($m) + D30($m) = C3($m) + C2($m) + I30($m)}
To decrease the run time of the FAM model, FAM uses a simplified schematic as shown in Figure 66.

Appendix H CS2CL Model Structure
and Implementation
H.1 Introduction
Most of CalLite’s hydrology, demand, and regulation requirement inputs are obtained by copying or
aggregating CalSim II input and output timeseries. Appendix A has a list of timeseries for CalLite
accretion/depletion terms and demands, which also shows the source timeseries from CalSim. The
CalLite input timeseries are obtained from the CalSim timeseries by either simple copying or
performing arithmetic operations. Prior to CalLite Version 2.00, MS Office Excel spreadsheets were
used to create the CalLite input timeseries, but this procedure proved to be tedious and errorprone.
Starting with Version 2.00 of CalLite, all timeseries input data are now contained in a CalLite SV file
in the HEC DSS format. The data in this SV DSS file are created by a WRIMS 2-based CalLite SV file
generating tool, called CS2CL (CalSim to CalLite), which is coded in the Water Resources Engineering
Simulation Language (WRESL). The CS2CL tool replaces the MS Office Excel method used with earlier
versions of CalLite. CS2CL generates the CalLite input SV file using a DSS file which contains all
timeseries from the SV (input) and DV (output) DSS files of a particular CalSim II run. Generating
these timeseries in a WRIMS 2-based model has a number of advantages, including: (1) consistency
in coding between the CalLite model and CS2CL, (2) easier maintenance and tracking of timeseries
properties in CalSim and CalLite, and (3) automated generation of input timeseries for CalLite.
CS2CL is designed so that the user can easily update the CalLite SV file with different system
assumptions and/or hydrology scenarios, by simply running a model with input and output
timeseries from a different CalSim II study. The CS2CL tool can then be used to re-generate the
CalLite SV DSS file automatically.
In the current CalLite release, fifteen CS2CL-generated outputted SV files are pre-generated and
already included: D-1485, Existing LOD with Pre-BO, Future LOD with Pre-BO, Existing LOD with BO,
Future LOD with BO, and ten climate change scenarios. When the SV and DV files of the CalSim II
base study are changed, it is necessary to create a new DVSV.DSS file using these files, and then
rerun CS2CL to generate a new CalLite input SV file prior to running the CalLite model.
The next sections explain the CS2CL model’s structure and its implementation.

Four cycles are used in the main file: mainCS2CL.wresl:
1. The first cycle is used to generate the two timeseries, SJR_ANN and VernWQfinal, which
have data for 5 steps before the first month of the simulation (Oct 1921). These timeseries
are required by the ANN DLL.
2. The second cycle is used to generate the timeseries UARM (Upper American River Model),
which has data for 1 step before the first month of the simulation starts. This timeseries is
required for computation of the American River Flow Management Standard.
3. The third cycle generates all of the other timeseries, which start in Oct 1921 and end in Sep
2003.
4. The final cycle generates timeseries for the San Joaquin.
H.3 CS2CL Model Implementation Guide
Following is a step-by-step guide for using the CS2CL Tool to create a CalLite SV file from a CalSim
study. A future study (F-Part = 2020D09E) is used for example. Replace all instances of “2020D09E”
below with “2005A01A” if running an existing condition study.
1) Run CalSim, save the DV file as 2020D09EDV.DSS (for example).
2) Copy 2020D09EDV.DSS and re-save as 2020D09EDVSV.DSS
3) Open this new DVSV.DSS file in HEC-DSSVue and drag and drop the 2020D09ESV.DSS file into the
list of timeseries. Click “Copy All”.
4) Repeat Step #3 to copy the timeseries over from “Other_timeseries_2020D09E”.
5) Ensure the correct pathnames are used in CS2CL_study.config. The run period should be set to
Oct 1920 – Sept 2004.
6) Run the CS2CL tool by double clicking on CS2CL_run.bat. It will output a DV timeseries for use as
a SV input timeseries in CalLite..

I.2 Batch file method
Below is a summary of the steps necessary to do the batch file method manual run, followed by a
more detailed step-by-step guide. The three steps are creating a directory, modifying the input files,
and running the batch file.
Creating the Manual CalLite Directory and Configuring the Batch File
1) Copy and paste the entire DEFAULT folder from CalLite_v3\Scenarios\Run_Details into the
same “Run_Details” folder and rename it. For the purposes of this tutorial, this new folder will
be renamed to “batchFileTest” and will be referred to as such from this point forward.
a. Note: you may copy/paste another study folder, other than DEFAULT, if you wish to
use that specific study as a starting point.
b. You may elect to create a new folder within the CalLite_v3 directory to store your
new studies, instead of “Run_Details”. Make sure to change the pathnames
appropriately in the following steps. For the purposes of this tutorial, the original
“Run_Details” folder will be used.
2) Copy/paste all the SV files from CalLite_v3\Model_w2\DSS_Files to
CalLite_v3\Scenarios\Run_Details\batchFileTest\Run\DSS. Alternatively, copy/paste only the
one needed for that study.
3) In the CalLite_v3 directory, copy/paste and rename the “group_0” batch file.
4) Modify the newly created batch file to point to the .config file in the new directory created in
step 1. (i.e. CalLite_v3\Scenarios\Run_Details\batchFileTest\batchFileTest.config). Use the
original group_0 as a reference.
Modifying the Input Files
1) Modify the .config file
a) Specify the SV, DV, and INIT DSS filenames, file locations, and the appropriate Level of
Development.
2) Modify the Lookup tables
a) Modify GUI_ related tables to manually set values (see details in the Step-by-Step guide
below)
b) Copy the files from the folders entitled "VariableDemand" (if using current SWP demands)
or "FutureDemand" (if using SWP future or user-defined demands) and replace the
corresponding lookup tables.
114
CALLITE DOCUMENTATION VERSION 3.00
Running the Model
Double clicking “D:\CalLite_v3\group_batchFileTest.bat” will run the respective study. The output
will be saved in the “DvarFile” path specified in the .config file.
I.3 Step by Step Guide
I.3.1
Creating the Manual CalLite Directory
Create a new directory in which to run CalLite without the GUI.
1) Copy and paste the entire DEFAULT folder from CalLite_v3\Scenarios\Run_Details into the
same “Run_Details” folder and rename it.
Copy/Paste
Figure 67. CalLite manual run directory.
‘Generated’ and ‘save’ are files generated by the GUI and are not necessary for a manual run;
they can be deleted.
115
CALLITE DOCUMENTATION VERSION 3.00
I.3.2
Copy the SV Files from Model_w2
Copy/paste the desired SV file(s) from CalLite_v3\Model_w2\DSS_Files to
CalLite_v3\Scenarios\Run_Details\batchFileTest\Run\DSS
All the SV files may be copied over, but the model will only use the one specified in the .config
file. See section I.3.4.1.
116
CALLITE DOCUMENTATION VERSION 3.00
I.3.3
Configuring the Batch File
The batch file “group_0.bat” calls the WRIMS2 engine to run the specified study.
The original batch file “group_0” reflects last study run from the GUI, so do not simply modify it, as
any changes will be overwritten when a new study is run through the GUI. A new batch file will need
to be created to initiate the manual run for the newly created study – make a copy of “group_0” and
rename it to reflect the name of the new study.
Copy/Paste
Within the newly created batch file (group_batchFileTest.bat), rename the directories to point to
the .config file of the new study.
@title = "%~dp0\Model_w2\runConfig_calgui
D:\CalLite_v3\Scenarios\Run_Details\batchFileTest\batchFileTest.config
batchFileTest"
%~dp0\Model_w2\runConfig_calgui
D:\CalLite_v3\Scenarios\Run_Details\batchFileTest\batchFileTest.config
batchFileTest
Before the new study can be run, the study parameters need to be changed. This is the subject of
the next section.
117
CALLITE DOCUMENTATION VERSION 3.00
I.3.4
Modifying the Input Files
To run a CalLite scenario, there are two set of modifications that need to be made to files in the
manual run directory regarding the .config file and lookup tables.
I.3.4.1
Modifying the .config File
The .config file contains the SV file F-part and directories for model inputs/outputs: these
parameters need to be changed to reflect those of the new study.
Specifying the SV file: Specify the path for the correct SV file from batchFileTest\Run\DSS. The SV
files were added to the study folder in step 1.3.2. Remember to change the SV file F-part (SvarFPart)
accordingly.
Specifying the DV file: Specify the path for the output DV file. This file will be created when a run is
started.
Specifying the INIT file: There is only one INIT file, but make sure the directory points to the INIT file
inside the newly created study.
*All pathnames should be checked to ensure they are not still referring to files in the DEFAULT study
(or the original study that was copied)
Figure 68. The .config file for the manually run study.
118
CALLITE DOCUMENTATION VERSION 3.00
I.3.4.2 Lookup Tables
This subsection describes changes to table files in the "Run\Lookup" folder. When running CalLite
using the GUI, the GUI writes the appropriate values into these files. When doing a manual run, the
values in these files need to be edited manually. The following six files are the basic tables that need
to be edited to setup a manual CalLite run: GUI_HydroClimate.table; GUI_Operations.table;
GUI_Regs.table; GUI_RPAsOtherRegs.table; GUI_RunBasis.table; and GUI_SODDemand.table;
(Figure 69).In addition, for changes made to south-of-Delta demands, some additional files need to
be copied.
The following sections describe how to change each table file, which files to copy, and how changes
in each file correspond to options in the GUI.

The Regulations dashboard in the GUI has two main frames that hold settings for D-1641 and D1485 regulations (the “D-1641/D-1485” tab and the right-hand-side table showing some regulation
values) (Figure 72). Values for the settings on this tab are saved in the GUI_Regs.table file (Indices 115). Each index corresponds to a different regulation. Below are the different options for each Index.
Option 0 – The regulation is off and will not be included
Option 1 – Default D-1641 regulation values will be used
Option 2 – User defined regulation values will be used (selected regulations)
Option 3 – Default D-1485 regulation values will be used
The regulations that can be user-defined are shown in Figure 72 with the table name shown next to
them in red. When the index value is set = 2, the corresponding table or tables must also be edited
to specify the desired user-defined values.

J.2 Modifying the Report Template File
Under the “Config” folder in the directory where CalLite was installed, there are report format files
with the .inp extension (Figure 84). By default CalLite comes with two of these files, one for
comparing two CalLite studies and one for comparing a CalSim study to a CalLite study.
Figure 84. Configuration folder.
These files can be opened using text editor software such as TextPad. The file can be broken down
into 9 different parts:
1) General Information: This portion displays the general information as compiled from the
DSS results files and the user input from the GUI. This does not need to be edited since the
report tool generates this information by default.
2) Display Name (VARIABLE): These are the names that will be displayed in the report for each
variable.
3) Category Type (VAR_CATEGORY): This denotes the category of the variable being reported
• S – Storage
• RF – River Flow
• DI – Delta Inflow
• DO – Delta outflow
• DE – Delta Exports
• SWPSOD – State Water Project South of Delta
• CVPSOD – Central Valley Project South of Delta
• ALLOC – Allocation
• X2 – Salinity (X2) position
• EC – Electrical Conductivity
136
CALLITE DOCUMENTATION VERSION 3.00
4) Data Type (REPORT_TYPE): This denotes the statistical category or the source of the variable
being reported. A “_Post” means the data has been post processed and may be a
combination of multiple variable results.
• Average – Averaged data
• Exceedance – Storage vs Percent at or Above
• Avg_Excd – Average vs Percent at or above
• Timeseries – results data that are not averaged or exceedance
5) DSS Pathname for First Study (PATH_BASE): These are the results DSS pathnames for the
