@USBR Increases Releases from the Aspinall Unit to Meet Flow Targets on the Gunnison River

Black Canyon of the Gunnison

Here’s the release from the US Bureau of Reclamation (Justyn Liff/Erik Knight):

The Bureau of Reclamation began increasing releases from the Aspinall Unit, consisting of Blue Mesa, Morrow Point, and Crystal reservoirs on the Gunnison River, on May 14, 2017. The increased release will attempt to meet flow targets on the Gunnison River, designed to benefit endangered fish species downstream while continuing to meet the congressionally authorized purposes of the Aspinall Unit.

Flows in the Gunnison River through the Black Canyon will increase at a minimum of 500 cubic-feet-per-second a day resulting in flows through the canyon that may reach 12,000 cfs by approximately May 23. Flows will remain around 11,500 cfs to 12,000 cfs for 3-5 days before incrementally decreasing toward a range of 5,000 cfs to 5,500 cfs around May 29.
