L.A. AQUEDUCT kNOW wHERE YOUR WATER COMES FROM

"There it is. Take it!" — William Mulholland

On November 5, 1913, William Mulholland dedicated the Owens River as a main water source for L.A.

Since the early 20th Century, the L.A. Aqueduct has sparked fierce controversy between the Owens Valley indigenous communities and the Los Angeles Department of Water and Power (LADWP). Today, the delicate relationship is sustained by mandated conservation and restoration efforts to preserve the watershed and wildlife that depend on it.

Owens Valley is the place where the Great Basin meets the Sierra Nevada Mountains in the Western United States.

Paiute and Shoshone Indians irrigated Payahuundadü, "Land of the Flowing Water," long before LADWP took over. The indigenous tribes built intricate ditch systems that brought water to the dry landscape. During the early 1900's, LADWP slowly purchased land in Owens Valley and the community lost their rights to land and water overtime.

Mono Lake is a salt lake located north of Owens Valley. LADWP diverted large amounts of water from Mono Basin streams between 1941 until 1990 causing Mono Lake to drop 45 vertical feet, lose half its volume, and double in salinity.

According to the Mono Lake Committee, "When Mono Lake stands between 6,380 and 6,391 feet on April 1, LADWP can export up to 16,000 acre-feet of water for the year. When the lake stands below 6380 feet on April 1, LADWP can export up to 4,500 acre-feet in a year, and when the lake level is forecast to go below 6377 feet, no exports are allowed." As of May 1, 2020, the lake level is 6,382.7 feet.

Landscapes in Los Angeles

Due to years of imported water dependence from the Owens Valley and Mono Basin, the City of Los Angeles encourages water-efficient landscapes for its businesses and residences.
