The Wyoming Area Office of the Bureau of Reclamation is preparing for contract construction work at Alcova Dam following the 2020 irrigation season. To accommodate the construction work, the reservoir will be temporarily lowered an additional 29 feet below the normal winter operating elevation of 5488 feet, down to elevation 5459 feet, which is below the level of the spillway crest.

Reservoir levels will not be affected during the summer and will remain at normal levels through the end of September. Spillway and stilling basin access work will start after October 1 and be completed by  March 31, 2021 to avoid peak spillway discharge season.

During the month of October, Alcova Reservoir will be lowered 39 feet at an average rate of about 15 inches per day. In a normal year, the reservoir is lowered about 5 inches per day for a total of 10 feet. The
flows below Alcova and Gray Reef Dams during October 2020 will be approximately 2000 cubic feet per second (cfs) through October 20, and then be reduced to the normal winter flow rate of 500 cfs. Alcova
reservoir is planned to be refilled to normal winter operating elevation in the last half of December. This will result in temporary higher than normal releases through the Miracle Mile and from Pathfinder Dam and minor declines in reservoir levels in Seminoe and Pathfinder Reservoirs. By January 1, 2021, Alcova Reservoir will be restored to its normal winter operating range.
