Sites Reservoir: Water for Dry Years
The water that Californians use for drinking, recreating and protecting the environment moves through a system that is arguably the most complex in the world.
Sites Reservoir Benefits
- Reliable dry-year water supply for California communities, farms and businesses
- Improved water quality
- Groundwater recharge
- Flood management
- Contribution to California’s renewable energy goals
- Environmental water in drier periods for native fish and Pacific Flyway habitat for migratory birds and other native species
- Recreational opportunities
- Creation and protection of middle-class jobs, including a large skilled workforce during seven-year construction
Where is Sites Reservoir?
The Sites Reservoir Project will be situated on the west side of the Sacramento Valley, approximately 10 miles west of Maxwell, Calif., in Glenn and Colusa Counties. The Sacramento Valley is a unique region, known for its farming community, rich agricultural benefits, and natural beauty. The region has been considered ideal for off-stream water storage since the 1980s, and the proposal is widely supported by local community leaders, residents, as well as state water managers and water agencies from the Bay Area to Southern California.
How Sites Reservoir Will Work
Sites Reservoir would capture and store stormwater flows from the Sacramento River – after all other water rights and regulatory requirements are met – for release in dry and critical years for environmental use and for California communities, farms, and businesses when it is so desperately needed.
When operated in coordination with other Northern California reservoirs such as Shasta, Oroville, and Folsom, which function as the backbone to both the Central Valley Project and the State Water Project, Sites Reservoir will greatly increase flexibility, reliability and resiliency of statewide water supplies in drier periods.
