From email from Reclamation (Dan Crabtree):

Crystal Dam has been operating at full powerplant release for most of this spring and summer. Now that Blue Mesa storage space has been regained and because of lower than expected late summer base flows, Reclamation will reduce reservoir releases in order to conserve reservoir storage. In addition, lower releases in the early fall months will provide more optimal flows for river recreation, fish studies scheduled for late September, and for the brown trout spawn which occurs during mid October to mid November. This change will also provide the flexibility needed to provide higher releases for power production during December and January.

Starting today, August 31, releases from Crystal Reservoir will be reduced by 100 cfs each day for the next four days, resulting in Black Canyon – Gunnison Gorge flows of 700 – 800 cfs. An additional flow reduction of 100 cfs could be forthcoming next week depending on conditions, with flows averaging around 600 cfs for September through November. Please reply to this email if you have further questions.
