Navajo Storage Unit, New Mexico The Navajo Dam has been completed and was dedicated in a ceremony held at the damsite in September 1962. During the year, additional work has been done by the Bureau and the Corps of Engineers in evaluating the potential flood control benefits of the project. The Navajo unit will provide irrigation water by storage of the flows of the San Juan River for the 110,630 acre Navajo Indian irrigation project and the San Juan-Chama project. It will also provide a limited quantity of water for a limited time for municipal and industrial use in northwestern New Mexico. In addition, the project will provide fish and wildlife, recreation, and flood control benefits. Principal features of the unit are the Navajo Dam and the 1,709,000 acre-foot Navajo Reservoir. Transmission Division The transmission division includes transmission lines, substations, switchyards, and other facilities to provide for interconnection of storage project powerplants with each other, with participating project power facilities, with other Federal powerplants, and with the electrical facilities of the major non-Federal power systems in the Colorado River Basin area, so that the greatest practicable amount of firm power and energy can be produced and delivered to the load centers for sale. The completed facilities will be operated by the Government.
