Navajo Reservoir On February 10th, the daily average release rate from Navajo Dam was approximately 429 cfs while reservoir inflow (modified unregulated) was averaging approximately 288 cfs. The water surface elevation was 6056.35 feet above sea level. At this elevation the live storage is 1.30 maf (77 percent of live storage capacity) and the active storage is 0.64 maf (62 percent of active storage capacity). NIIP is diverting 34 cfs. The river flow measured at the Animas River at Farmington USGS gage was at 202 cfs. River flow at the San Juan River at Four Corners USGS gage was 794 cfs

Releases from Navajo Dam are made for authorized purposes of the Navajo Unit and are pursuant to the Record of Decision for the Navajo Reservoir Operations.

Preliminary modified-unregulated inflow into Navajo (inflow adjusted for upstream change in storage, reservoir evaporation and exportation from the basin) in December was 16 kaf (77 percent of average for the month).
Forecast modified-unregulated inflow to Navajo over the next three months (February, March, and April) are projected to be: 20 kaf (66 percent of average), 51 kaf (55 percent of average), and 92 kaf (54 percent of average), respectively.

The April through July runoff forecasts are as follows:
Min Probable: 320,000 af (43 percent of average)
Most Probable: 500,000 af (68 percent of average)
Max Probable: 815,000 af (111 percent of average)

Releases for the fall and winter will be made to target the San Juan River Recovery Implementation Program's recommended baseflow range of 500 cfs to 1000 cfs. Releases will likely range between 300 cfs and 600 cfs throughout the winter. 

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 Unit Coordination Meeting will be held Tuesday, April 21, 2020 at 1:00 pm at the Farmington Civic Center (200 West Arrington, Farmington, NM).
