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.

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.
