Sites Reservoir Project

Sites Reservoir Project A 21st-century water storage project — made for California's communities, farms and environment.

Sites is an innovative and modern water storage project that secures long-term water sustainability and benefits California’s economy and environment now and into the future. It goes well beyond water supply and flood protection by adding flexibility and generating a much needed new water source. Sites is a local project, being developed by a consortium of local government agencies who are motivat

ed to build local water sustainability and to do so in a way that helps the state meet its overall water system needs.
