Navajo Dam Technical Working Group

Navajo Dam

Purpose and Participation

This meeting was held in Farmington, New Mexico at the Civic Center on August 21st, 2019. The meeting minutes, as mailed, as well as the meeting handouts are available in the archives. Meeting attendance is shown on the archived minutes.

The purpose of these meetings, held annually in January, April, and August, is to gather stakeholder input for determining upcoming operations for Navajo Reservoir. This input is used in Reclamation’s development of an overall 24-month study for operation of Reclamation projects in the Upper Colorado River Basin, which includes plans for Glen Canyon, Flaming Gorge, Aspinall Unit and Navajo. Input from individuals, organizations, and agencies along with other factors such as weather, water rights, endangered species requirements, flood control, hydro power, recreation, fish and wildlife management, and reservoir levels, will be considered in the development of these reservoir operation plans. In addition, the meetings are used to coordinate activities and exchange information among agencies, water users, and other interested parties concerning the San Juan River and Navajo Reservoir.
