Clifton Court Forebay is a reservoir located in the San Joaquin Valley of California. It was created in 1969 as a part of the California State Water Project and serves as a regulating and storage facility for water that is pumped from the Sacramento-San Joaquin Delta. Its primary purpose is to provide water to the South Bay Aqueduct, which serves the Santa Clara Valley and the San Francisco Bay Area. The reservoir is fed by several rivers and streams including the San Joaquin River and the Sacramento River. It also receives water from the Sierra Nevada snowpack, which is an important source of water for California. The reservoir is used for agricultural irrigation and as a recreational facility for activities such as fishing and boating.
