Lake Crowley is a man-made reservoir located in the Eastern Sierra region of California. It was created in 1941 as part of the Los Angeles Aqueduct system and is named after the former Los Angeles Department of Water and Power Commissioner, Mulholland's assistant, and long-time employee of the LAWD, William Mulholland Crowley. The lake is fed by surface flows from the Owens River and snowpack runoff from the nearby Sierra Nevada mountains. The water from the lake is used for agricultural purposes in the Owens Valley and for drinking water in Los Angeles. The lake is also a popular recreational destination for fishing, boating, and camping. Despite controversies surrounding its creation, Lake Crowley remains an important source of water for Southern California.
