Sites Reservoir: Water for Dry Years
Now more than ever, California needs innovative solutions to ensure we have a sustainable water supply. Our climate has changed, and we need more storage as the West gets drier and hotter to ensure we have enough water to meet our needs.
Sites Reservoir is a unique, multi-benefit water storage project that will capture and store water from major storms, so water is available to California’s communities, farms, and environment during dry periods.
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’s communities, farms and environment
- Dedicated environmental water for native fish, migratory birds, and their habitats
- Adaptable to climate change
- Contribution to California’s renewable energy goals
- Flood management
- Recreational opportunities
- Job creation, including a large skilled workforce during construction

A Part of the Sacramento Valley
Sites Reservoir would be located on the west side of the Sacramento Valley, near Maxwell, California – a rural farming town in Colusa County, approximately 65 miles northwest of Sacramento. The Sacramento Valley is known for its farming community, rich agricultural benefits, and natural beauty. The region’s acres of grassland surrounded by rolling foothills make it an ideal location for off-stream water storage. 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.
A 21st Century Water Storage System
Sites Reservoir is a water savings account for dry years. It would capture and store stormwater flows from the Sacramento River—after all other water rights and regulatory requirements are met—and release the water for California communities, farms, and environmental agencies to use when it is desperately needed.
Sites Reservoir complements other major reservoirs like Shasta, Oroville, and Folsom, which function as the backbone to both the Central Valley Project and the State Water Project. Sites Reservoir will help optimize water releases from this existing network, greatly increasing the flexibility, reliability and resiliency of statewide water supplies.

#DidYouKnow: Migrating Pacific Flyaway waterfowl rely on Sacramento Valley’s water supply to rest and feed year-round, especially the region’s rice fields.
Sites Reservoir will allocate a significant share of its stored water to the environment, including water to maintain the region’s rice fields, sustaining Pacific Flyaway habitats.

Did you know the Sites Project Authority has committed to a “net zero” threshold for greenhouse gas emissions over the life of the project? This includes avoiding and minimizing emissions from construction and operations, and when needed, offset actual emissions through onsite measures, offsite measures, and carbon credits.

Sites Reservoir is designed with California’s future in mind.
State leaders have set a goal of creating storage space for 4 million acre-feet of water to capitalize on big storms and capture that water for future use. Sites is an essential part of increasing that water storage capacity as hotter and drier weather diminishes our water supply.

Sites Reservoir was awarded $67.5 million in federal funding from @usinterior as part of their efforts to add additional water storage capacity in the western region of the United States. This investment is another step closer to achieving our final funding goal, building this generational project, and providing significant benefits to California’s communities, farms, and environment.
