On Saturday, September 6, 2025 at 6pm MT, Reclamation will decrease releases from Crystal Dam to 1,450 cfs from the current release of 1,500 cfs. Gunnison Tunnel diversions remain at 1025 cfs. Gunnison River flows in the Black Canyon/Gunnison Gorge, currently ~460 cfs, are anticipated to decrease to ~410 cfs. This schedule will remain in effect until a new notification is issued. Scheduled releases are subject to changes with changes in river flows and weather conditions.
Releases are made for the authorized purposes of the Aspinall Unit, and to maintain target base flows through the endangered fish habitat along the Gunnison River between Delta and Grand Junction.
