From email from Reclamation (Dan Crabtree):
It’s now time to start adjusting releases from the Aspinall Unit for the fall season. Flows from Crystal Reservoir will be reduced by 150 cfs starting at 8:00 a.m. on Friday October 2nd. Flows in the Black Canyon and Gunnison Gorge should then be approximately 680 cfs. Further reductions may be forthcoming in the following weeks. We are anticipating low flows in the Black Canyon and Gunnison Gorge in the 500 cfs range during October and November.
