## Central Valley Project Water Supply

The Central Valley Project was built primarily to integrate California's water way to protect against crippling water shortages and hazardous floods; it also produces hydroelectric power and provides flood protection, navigation, recreation and water quality benefits. The CVP serves farms, homes and industry in the Central Valley, San Joaquin Valley and the San Francisco Bay Area. This multiple-purpose project plays a key role in California's powerful economy, providing water for 6 of the top 10 agricultural counties in the nation's leading farm state. The CVP is the largest single source of irrigation water in the state while also dedicating 800,000 acre-feet per year to fish and wildlife pursuant to the 1992 Central Valley Project Improvement Act.
