Navajo Reservoir – Navajo is currently releasing 350 cfs. Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell). The San Juan River Basin Recovery Implementation Program (SJRIP) recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area.
Modified unregulated inflow into Navajo during the month of March was 83,316 af, which was 90% of average. The reservoir elevation is 6,067.4 ft and increasing.
Inflows for the next three months are projected to be below average: with April, May and June forecasted inflow volumes at 120,000 af (70% of average), 220,000 af (79% of average), 160,000 af (72% of average), respectively. The most probable April through July forecast is for 530,000 af (72% of average). Under this forecast, a spring peak release of 5,000 cfs for 33 days is expected beginning in early-to-mid May. Until the spring peak release begins, Navajo is expected to release 350 cfs.
Reclamation conducts Public Operations Meetings three times per year to gather input for determining upcoming operations for Navajo Reservoir. 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. The next Navajo Public Operations Meeting is scheduled for April 26th at 1pm at the Farmington Civic Center, Farmington, NM.
