Aqueduct Operations
For over a century, LADWP has had a significant presence in the Owens Valley. Construction of the First Los Angeles Aqueduct in 1913 and the second in 1970, have provided the majority of L.A.’s water supply historically from the Eastern Sierra.
LADWP operates a number of key facilities involved in delivering water and power safely and reliably to the City of Los Angeles, as well as to 6,000 electric customers in the Owens Valley, and directly employs nearly 350 people in the Eastern Sierra area. In addition to our water and power operations, construction and maintenance forces, LADWP administers leases and other land-use activities ranging from ranching and grazing to campgrounds and golf courses, and from local businesses to homes.

Projects & Reports
Bishop Training Facility and Construction Yard Project
LADWP is constructing a new multi-use training facility and constructing a new more functional and localized LADWP construction yard that will be located between Bishop Creek Canal, U.S. Highway 6, and Wye Road, Bishop, CA. The facilities will offer workforce development resources, provide indoor and outdoor spaces for construction and maintenance of typical LADWP water and power infrastructures, as well as foster community well-being and economic growth for the region.
Little Lake Aqueduct Crossover Trunk Line
The Little Lake Aqueduct Crossover Project consists of the design and construction of a crossover pipe, within the rights-of-way of the First Los Angeles Aqueduct to the Second Los Angeles Aqueduct located about 11.8 miles south of the Haiwee Power Plant near Olancha, CA. This construction does not impact public use of any recreation spots.
North Haiwee Dam No. 2
North and South Haiwee Reservoirs are the southernmost Los Angeles Aqueduct reservoirs in Inyo County separated by Merritt Dam. Haiwee Reservoirs are approximately 5 miles south of the intersection of US-395 Highway and SR-190 and just east of US-395 Highway. Construction of North Haiwee Dam was completed in February 1913. The purpose of the Project is to contain the water in North Haiwee Reservoir in the event the existing North Haiwee Dam fails due to an earthquake.
