MILLS, Wyoming – The Bureau of Reclamation will temporarily use the spillway at Alcova Dam to make scheduled water releases to the North Platte River. This action is necessary to accommodate scheduled maintenance activities in the powerplant. The river flow below Gray Reef Dam will continue to be at about 500 cubic feet per second (cfs), as it has been all winter.
This water operation will begin on January 11, and will last until January 25, or completion of the maintenance. All releases from Alcova Dam will be stored in Glendo reservoir. The releases will again be made through Alcova Powerplant when repairs are completed.
Alcova Dam is on the North Platte River about 35 miles southwest of Casper, Wyoming. The dam forms a reservoir from which water is diverted into Casper Canal for irrigation of lands in the Kendrick Project near Casper. Winter releases from Alcova Reservoir generally provide power generation and relocate storage water into Glendo Reservoir for delivery the following spring and summer. Alcova Powerplant is located just downstream of Alcova Dam and has two 20.7 megawatt generating units.
