Navajo Reservoir – Navajo is currently releasing 4,000 cfs and is conducting a spring peak release. 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 May was 209 kaf, which was 75% of average. The reservoir elevation is 6075.3 ft and increasing.
Inflows for the next three months are projected to be below average: with June, July, and August forecasted inflow volumes at 186 kaf (83% of average), 31 kaf (47% of average), and 27 kaf (60% of average), respectively. The most probable April through July forecast is for 545 kaf (74% of average).
The spring peak release began May 18th. The release was reduced to 2000 cfs at the request of the San Juan County office of Emergency Management on May 25th due to safety and property concerns. Since that time, Reclamation has coordinated daily with the OEM to slowly increase releases with the goal of reaching 5,000 cfs. The ramp-down is scheduled to begin June 23rd, but the schedule may change if cirumstances warrant.
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 August 23rd at 1pm at the Farmington Civic Center, Farmington, NM.
