Castaic Dam is a dam near the city of Castaic, California. It is an earth-fill dam, though its surfaces are covered with boulders and cobble-sized rocks to prevent erosion. Although located on Castaic Creek and forming Castaic Lake, Castaic Creek provides little of its water. The lake is the terminus of the West Branch of the California Aqueduct, part of the State Water Project. The dam was built by the California Department of Water Resources and construction was completed in 1973. The lake has a capacity of 325,000 acre-feet (401,000,000 m³) and stores drinking water for the western portion of the Greater Los Angeles Area.
