Stone Canyon Reservoir
Stone Canyon Reservoir and Upper Stone Canyon Reservoir are adjoining reservoirs in the Westside region of Los Angeles, California, located in the neighborhood of Bel Air. Situated in the Santa Monica hills at 847 feet (258 m) above sea level, the reservoirs lie south of Mulholland Drive and west of North Beverly Glen Boulevard. The main reservoir is the Stone Canyon Reservoir with the much smaller, cone-shaped Upper Stone Canyon Reservoir adjoining it to the north. The two reservoirs supply the Westside water subsystem, including service to around 400,000 people in Pacific Palisades, the Santa Monica Mountains, and West Los Angeles.
