San Luis Reservoir and Dam

The San Luis Dam is the fourth largest embankment dam in the USA, and holds back the 12,700-acre San Luis Reservoir. This reservoir is part of the California State Water Project, a network of dams, reservoirs, pumping stations, and 550 miles of canals and major conduits, that distribute water from Northern California to the agricultural industries of the San Joaquin Valley, and to the metropoli of Southern California.
