Stone Canyon Reservoir

Situated in the Santa Monica Mountains at 847 feet (258 m) above sea level, the reservoirs lie in the Bel Air neighborhood, south of Mulholland Drive and west of North Beverly Glen Boulevard.The two reservoirs supply the Westside water subsystem,[1] including service to around 400,000 people in Pacific Palisades, the Santa Monica Mountains, and West Los Angeles.Seismic studies were carried out in 2002 and the conclusion was that the Lower Stone Canyon Dam could be "operated safely with the reservoir level at its design elevation of 865 feet (264 m).[9] Taking advantage of the natural terrain, an inclined tower was built that eliminated the need for an access bridge and reduced the unit bearing load.To compact the area brush and reduce the height of the flammable materials, heavy drums were filled with water and then rolled up and down the slopes.Proposed 2004 system changes included removing the reservoir from normal operating service, and retaining it for emergency storage only.The Federal and State Surface Water Treatment Rules prescribed that covering of all smaller reservoirs and building of filtration plants at all large ones was essential.[14] Planning for further improvement in treatment and supply facility was undertaken in 2004 to ensure removal of potential contaminants from the Lower Stone Canyon Reservoir water.This plant was located in a valley on the left abutment of Lower Stone Canyon Dam near the existing reservoir outlet.Half of this length is submerged below the surface of the lower reservoir, bypassing it from where the treated water is directly supplied to the customers from the Los Angeles Aqueduct Filtration Plant in Sylmar.[19] Page one of the first galley proofs of Irving Wallace's 1974 novel The Fan Club is set overlooking Stone Canyon Reservoir.
