***Notices for the latest release changes are posted HERE.***

Navajo Reservoir - On June 1, 2026, the daily average release rate from Navajo Dam was 800 cfs. The water surface elevation was 6036.3 feet above sea level. At this elevation the live storage is 1.023 maf (62 percent of live storage capacity). Diversions to Cutter Reservoir for the Navajo Indian Irrigation Project (NIIP) and the Navajo Gallup Water Supply Project (NGWSP) were 418 cfs. The San Juan-Chama project was diverting 117 cfs from the basin above Navajo Reservoir.

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. Releases target the San Juan River Recovery Implementation Program's (SJRIP) recommended downstream baseflow range of 500 cfs to 1,000 cfs through the critical habitat reach of the San Juan River (Farmington, NM to Lake Powell).

Navajo was at 6036.5 ft of pool elevation and 1.024 maf of live storage by the end of May, which was 73 percent of average for the end of the month. The release averaged 569 cfs and totaled 35.0 kaf, which was 33 percent of average for the month. Preliminary modified unregulated inflow (MUI) into Navajo was 63.1 kaf, which was 26 percent of average for the month. Calculated evaporation for the month was 2.9 kaf. NIIP diverted a total of 28.4 kaf. Navajo had a net storage change of -2.1 kaf during the last month.

The most probable MUI forecast for June, July and August is 8 kaf (4 percent of average), -10 kaf (-21 percent of average), and -2 kaf (-6 percent of average), respectively.

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 meeting will be held on August 18th from 1-3pm. The meeting will be entirely virtual, to attend email cfelletter@usbr.gov for a meeting invite.
