GRAND JUNCTION, Colo. - Reclamation will begin increasing releases from the Aspinall Unit, consisting of Blue Mesa, Morrow Point, and Crystal reservoirs on the Gunnison River, on May 23, 2014, as required by the Record of Decision for the Aspinall Unit Operations Final Environmental Impact Statement. 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.

Beginning on May 23, 2014, flows in the Gunnison River through the Black Canyon will begin increasing at a minimum of 500 cubic-feet-per-second a day resulting in flows through the canyon of around 9,000 cfs on June 2, 2014. Flows will remain at or above 8,000 cfs for 10 days before incrementally decreasing toward a range of 4000 cfs to 5000 cfs by the middle of June 2014.
