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.
Annual Water Quality Report Mountain View Trailer Court
The 2023 Drinking Water Quality Report for the Mountain View Trailer Court (MVTC) was prepared by LADWP. This annual Drinking Water Quality Report (also known as a Consumer Confidence Report CCR) is required by the California State Water Resources Control Board, Division of Drinking Water (SWRCB-DDW) and is prepared in accordance with their guidelines. The report provides information about drinking water at MVTC during the 2023 calendar year (January 1, 2023 - December 31, 2023). Only those constituents that were detected are listed.
Mountain View Trailer Court Water System-Lead Service Line Inventory
LADWP-Mountain View Trailer Court water system has completed the initial lead service line inventory required by U.S. EPA’s Lead and Copper Rule Revisions. The deadline for the initial inventories was October 16, 2024.
Through completing a historical records review and field investigations, LADWP has determined it has no lead or galvanized requiring replacement service lines in its distribution system.
LADWP reviewed all applicable sources of information, including:
• All construction and plumbing codes, permits, and existing records or other documentation which indicates the service line materials;
• All water system records, including distribution system maps and drawings, historical records on each service connection, meter installation records, historical capital improvement or master plans, and standard operating procedures;
• All inspections and records of the distribution system that indicate service line material, including inspections conducted during the course of normal operations (e.g., checking service line materials when reading water meters or performing maintenance activities); and
• All previously conducted service line or meter replacements.
All service lines were determined to be non-lead.
LADWP will update service line material information obtained from future normal operations, such as service line maintenance, or installation, and will update the initial inventory accordingly.
