Flow will likely be ramping down this weekend:
The Bureau of Reclamation will be increasing the release from Crystal Reservoir by 200 cubic feet per second (cfs) from 1600 cfs to 1800 cfs on Monday, October 4 at 6:00 a.m. Releases at Crystal Reservoir are being increased in order to accommodate the Colorado Division of Wildlife's annual trout census work on the Gunnison River. After completion of the trout census on Thursday, October 7, releases will be returned to 1600 cfs. The final release rate of 1600 cfs at Crystal Reservoir will be maintained until further notice.
As of today the Gunnison Tunnel is diverting 1000 cfs and flows in the Gunnison River through the Black Canyon are around 600 cfs. After the change on Monday, Gunnison Tunnel diversions should still be around 1000 cfs and flows in the Black Canyon should be around 800 cfs. River flows will return to 600 cfs after completion of the trout census. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
