Navajo Reservoir – As of September 12th, 2016, Navajo reservoir elevation is 6058.4 ft (1.327 maf live storage) and is releasing 500 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 August was 30 kaf, which was 67 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 September, October, and November forecasted inflow volumes at 23 kaf (55 percent of average), 30 kaf (64 percent of average), and 31 kaf (93 percent of average), respectively. For more forecast information, please visit the CBRFC website links in the Water Supply Forecast tab below.
The spring peak release began May 18th. The release was reduced to 2,000 cfs at the request of the San Juan County office of Emergency Management (OEM) on May 25th due to safety and property concerns. Reclamation coordinated daily with OEM to safely increase the release with the goal of reaching 5,000 cfs. The maximum release reached was 4,720 cfs on June 5th. The release was decreased to 4,200 cfs for most of the remainder of the spring peak release. Ramp-down for the spring peak release began on July 1st and was complete by July 11th. 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. For more meeting information, please click "Navajo Public Operations Meetings" under the Working Group tab below.
The next Navajo Public Operations Meeting is scheduled for January 24th, 2017, at 1pm at the Farmington Civic Center, Farmington, NM.
