From email from the Bureau of Reclamation (Conor Felletter):
On Monday, August 11 at 8pm MT, Reclamation will increase releases from Crystal Dam to 1,700 cfs from the current release of 1,650 cfs. Gunnison Tunnel diversions remain at 1025 cfs. Gunnison River flows in the Black Canyon/Gunnison Gorge, currently ~590 cfs, are anticipated to increase to ~640 cfs.
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.
Reclamation conducts Public Operations Meetings three times per year to gather input for determining upcoming operations for the Aspinall Unit & Gunnison River. 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 Aspinall Unit & Gunnison River. The next Operations Group meeting will be held on August 21, 2025 at 1:00 p.m in Montrose, CO at the Holiday Inn Express (1391 S. Townsend Ave). This meeting is open to the public with a virtual option using Microsoft Teams. Register for the webinar at this link.
