Navajo Reservoir – As of November 30th, 2016, Navajo reservoir elevation is 6055.9 ft (1.296 maf live storage) and is releasing 350 cfs. Releases are made for the authorized purposes of the Navajo Unit, and pursuant to the 2006 Record of Decision, in an 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 November was 24 kaf, which was 71 percent of average. The total April-July modified unregulated inflow into Navajo for 2016 was 566 kaf, 77% of average.
Inflows for the next three months are projected to be below average: with December, January, and February forecasted inflow volumes at 20 kaf (80 percent of average), 18 kaf (82 percent of average), and 21 kaf (69 percent of average), respectively.
Releases will be made to maintain target baseflows in the critical habitat reach for the remainder of the year.
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 January 24th, 2017, at 1pm at the Farmington Civic Center, Farmington, NM.
