## Model Overview

- Application of CALSIM II to Friant System

## CALSIM Development for USJRBI, Phase IIncorporate Real-time Operational Decision Logic for Operation of Millerton Lake

**Water supply allocation based on available water supply**
- Class 1, Class 2, and 215 water allocation made in March and updated monthly through end of June
- Monthly use of Class 1 and Class 2 are dynamic based on availability of Class 2 and 215 water
**Flood operation based on seasonal runoff**
- Water supply forecast used in February and updated monthly through end of June to target filling Millerton by end of June
- Pre-release for snowmelt runoff are made each month from February through May

##  Model Validation

**Compare Model Simulation to Historical Operation**
**Findings:**
**Model adequately mimics historical operation **
**Model simulation provides “benchmark” for comparative analysis**

## Annual Water Supply Forecast

**Water Supply Volume Available for Delivery = **
- + Beginning of Month Storage
- + Inflow (through September)
- - Canal Loss (through September)
- - Minimum River Release (through September)
- - Evaporation Estimate (through September)
- - Carryover Target (end of September)
**Updated Monthly From March Through June**

## Annual Class 1 Allocation

**Minimum of**
**Water Supply Volume Available for Delivery **
**800,000 AF**
**Updated Monthly From March Through June**

## Annual Class 2 Allocation

**Minimum of**
**Water Supply Volume Available for Delivery **
**	****Minus **
- Class 1 Allocation
- Spill forecast
**1,400,000 AF**
**Updated Monthly From March Through June for Spills**
**Adjusted for Wetness in Tulare Basin**

## Monthly Delivery Pattern

**Patterns are developed based on deliveries from 1982-1997**
**4 Sets of Monthly Patterns **
- Total Friant-Kern Canal
- Friant-Kern Canal Class 1
- Total Madera Canal
- Madera Canal Class 1
**CALSIM uses annual delivery allocation to select pattern**
**Class 2 Pattern is the Difference Between Total and Class 1**

## Historical Total Delivery Pattern

## Historical Class 1 Delivery Pattern

## Total Delivery Patterns

## Class 1 Delivery Patterns

## Snowmelt Release Forecast

**Volume of Friant release, above Class 1 and Class 2,  to be made with the target of filling by the end of June**
**Spill volume is spread throughout spring, the pattern of release is based on spill volume**
**Updated Monthly From February Through June **
**Snowmelt Release Volume = ****	**
**	**+ March 1 Storage
- 	+ Inflow (through June)
- 	- Canal Loss (through June)
- 	- Minimum River Release (through June)
- 	- Evaporation Estimate (through June)
- 	- Maximum Millerton capacity
- 	-	Canal Delivery

## Delivery Adjustment

**Friant-Kern Canal Class 2 delivery is reduced based on Tulare Basin wetness**
**Natural Flow of Tule River is used as wetness indicator**
**Madera Canal delivery is reduced based on Madera Canal service area demands**

## 215 Water Allocation

**Allocation is made only when Friant will spill for Rain flood or pre-release for snowmelt**
**215 water will not be allocated when delivery is reduced due to basin wetness**
**215 demand is 1,200 cfs for Friant-Kern Canal**
**215 demand is 100 cfs for Madera Canal**
