Navajo Dam, 402 ft (123 m) high and 3,648 ft (1,112 m) long, NW N.Mex., on the San Juan River, near the Colo. line; built 1958–63 by the U.S. Bureau of Reclamation. The dam, a major unit of the Colorado River storage project, regulates the flow of the San Juan River and provides flood control. Water impounded by the dam is used by the Navajos to irrigate a significant portion of land on the Navajo Native American Reservation.
