Water Resources

Welcome to Napa Water!

Water is the life blood of California’s economy and the underpinning of its diverse ecosystems. As such, water supply and water quality are critical issues facing the state’s agricultural, urban, and natural ecosystems now and into the future. As a primarily rural area with a strong agricultural economy and commitment to open space, Napa County has a vested interest in ensuring a stable and reliable water supply for all stakeholders and encouraging water resiliency across our diverse ecosystems.
