From email from Reclamation (Dan Crabtree):
Blue Mesa Reservoir has filled to about elevation 7491 ft leaving 28 ft or 242,000 ac-ft to fill. At the current rate of inflow and outflow, it would take over a month to fill the reservoir. As a result, after assessing the latest April through July forecast and the current runoff rates into the Aspinall Unit, Reclamation has decided to further reduce releases from the Aspinall Unit in order to slightly accelerate the fill of Blue Mesa Reservoir. This release reduction will begin on Friday, June 17th, continue through the weekend, and result in a Gunnison River flow of about 2,100 cfs through the Black Canyon and Gunnison Gorge.
