Navajo Unit
The San Juan River begins on the southern Continental Divide in the San Juan Mountains. Navajo Dam is in northeastern New Mexico about 34 miles east of Farmington. The dam is a rolled earthfill embankment containing three “zones” of selected cobbles, gravel, sand and clay, and is nearly three-quarters of mile long. Under normal conditions, water is released into the San Juan River downstream through the outlet works. Water from the river is used for irrigation, municipal and industrial purposes, by oil and gas fields and by thermal powerplants. Water is also released from Navajo Lake through a tunnel into an aqueduct for use on the Navajo Indian Irrigation Project. The Navajo Unit has helped to further manage the water resources of the Upper Colorado River Basin. By providing irrigation waters for lands on the Navajo Indian Irrigation Project, the Navajo Unit has helped meet irrigation requirements for the Navajo Nation. In addition, water releases help to maintain a continuous flow of water for power generation at Glen Canyon Dam.
