SARCCUP Benefits
∗ Habitat Creation & Arundo Removal
(conserved water supply)
∗ Water Use Efficiency - Turf Removal & Conservation-Based Rates (conserved water supply)
∗ Groundwater Bank (New Dry-Year Yield)
Total New Water Supply
New Water Supply
2,000 AFY
7,500 AFY
60,000 AFY
69,500 AFY
Groundwater Bank Goals
∗ Lower overall water cost ∗ Optimize Imported water
supplies ∗ Cheaper than the “spot market”
∗ Provide dry year yield during drought periods ∗ Proactive approach ∗ Reduce the impact of drought

Key Findings
1. Climate change has little impact on SARCCUP deliveries
2. CA Water Fix reduces ultimate size of SARCCUP bank
3. Optimum bank capacity appears to be around 300,000 AF
4. SWP conveyance capacity could be main constraint
