Mulholland Dam, Gravity dam in Hollywood Hills, United States.

The concrete Mulholland Dam rises 183 feet high in the Hollywood Hills, forming a substantial reservoir that serves Los Angeles water system needs.

The Bureau of Water Works and Supply constructed this curved concrete structure between 1923 and 1924 under William Mulholland's engineering direction.

The dam received its name to recognize William Mulholland's contributions to Los Angeles water infrastructure development through multiple engineering projects.

The Hollywood Reservoir, created by the dam, maintains a storage capacity of 7,900 acre-feet of water collected from various aqueducts and Weid Canyon.

Following the St. Francis Dam collapse in 1928, engineers conducted thorough safety reviews and implemented measures to maintain reduced reservoir capacity.
