Aspinall Unit Reservoirs
(Last Updated: July 18, 2016)
Crystal Dam is currently releasing 2000 cfs with 1100 cfs being diverted through the Gunnison Tunnel and approximately 1000 cfs flowing through the Black Canyon. Current flows of the Gunnison River in the Whitewater reach are approximately 1510 cfs. The June unregulated inflow to Blue Mesa Reservoir, 285 kaf (109% of average) was well above the forecasted volume of 225 kaf (86% of average). As a result, the end of June reservoir elevation for Blue Mesa (7414.84 feet) was about 5 feet higher than was projected in the June 24-Month Study. The elevation of Blue Mesa reached a peak of 7415.98 feet with a corresponding storage level of approximately 799 kaf (about 96% of full capacity) and is now decreasing each day in preparation for fall and winter operations. The projected elevation of Blue Mesa on December 31, 2016 is 7489.1 feet above sea level (just under the icing target).
Inflows to Blue Mesa for the next three months are projected to be below average: with July, August and September forecasted inflow volumes of 94,000 af (83 percent of average), 50,000 af (79 percent of average) and 35,000 af (92 percent of average), respectively.
The Aspinall Unit Working Group is an open public forum for information exchange between Reclamation and the stakeholders of the Aspinall Unit. The public is encouraged to attend and comments on the operations and plans presented by Reclamation at these meetings. Meeting notes from past working Group meetings are posted on the Working Group webpage.
