California voters passed Prop 1 to invest in water storage that benefits people and the environment. Sites Reservoir will be the first and only reservoir in the state to have dedicated environmental water to support wildlife and ecosystems.

Sites Reservoir is built to work with the Sacramento Valley's existing local infrastructure. More than 100 miles of existing canals and pipelines will help capture and deliver water where it's needed most.

California’s working lands do more than grow food; they sustain whole ecosystems. Up to 500,000 acres of rice fields help support wildlife each year. Water from Sites Reservoir will support local farmland that doubles as a resting spot for the Pacific Flyway.

Sites Reservoir will store 1.5 million acre-feet of water, increasing Northern California's storage capacity by up to 15%. It's a key part of California's Water Supply Strategy to expand storage by 4 million acre-feet statewide.

As climate change continues, California’s water supply faces growing risks. That’s why Sites Reservoir is designed to capture water during heavy storms and save it for dry years, when it’s needed most by farms🌾, families🏡, fish🐟, and fowl 🦆.

Sites Reservoir will be located on the west side of the Sacramento Valley, near the rural farming town of Maxwell, CA. The Sites Project Authority has worked with the local community to design a project that reflects the best interests of California's water future.

Congratulations to Fritz Durst, our Authority Board Chair, on receiving the 2026 Will S. Green Award from @NorCAWater! Thank you for all you do for our organization and the Sacramento Valley. https://t.co/JJFIvRWi2n

An acre-foot is a common measurement to describe how big reservoirs are—but what is an acre-foot and why is it called that? One acre-foot is enough water to flood an entire acre one foot deep. That’s about the size of a football field!🏈

The Sites Reservoir project site is a naturally bowl-shaped landscape, making it the perfect location for a reservoir. By using existing local infrastructure, the project also minimizes its impact on the surrounding environment.

We had a great time at the 61st Annual Colusa County Farm Show last month. Our team shared how Sites Reservoir will help support local economies, strengthen California’s water future and provide long-term benefits for farms, communities, and the environment.

Thank you everyone!

[Sites Reservoir Project @SitesProject]

As California faces new challenges like longer droughts, less snowpack, and more frequent rainstorms, Sites Reservoir will be able to capture water and help us protect our water future. It’s time to think big and #BuildSitesNow.

[Sites Reservoir Project @SitesProject]

Sites Reservoir is designed to work alongside California's existing water network to help provide reliable water during dry years for California’s communities, farms and the environment.

The Sites Reservoir Project continued to build momentum in 2025 with key funding, environmental, and permitting advancements. Read our latest blog for @norcalwater to learn more about our progress last year and what's ahead in 2026. https://t.co/kqf32Xx1TL

[Sites Reservoir Project @SitesProject]

Did you know Sites Reservoir is designed as a rain-fed reservoir? As California gets more intense rainstorms, Sites Reservoir will capture and store a portion of high river flows to use during dry years.

Sites Reservoir will be the first reservoir in California dedicated to capturing and storing water for the environment. It’s part of the project’s novel approach to managing water in California. #BuildSitesNow
