Annual Drawdown of Alcova Reservoir

For Release: Sep 14, 2022

MILLS, Wyoming – The Bureau of Reclamation will be lowering the water level in Alcova Reservoir as the 2022
irrigation season draws to a close. The annual drawdown of the reservoir will begin on Saturday, Oct. 1.


During October, the reservoir water surface elevation will be lowered about 10 feet, at a rate of approximately four
inches per day. The reservoir’s normal winter operating range is between 5,487 and 5,489 feet.
Water released in the drawdown of Alcova Reservoir will be restored downstream in Glendo Reservoir.
Boat owners and recreationists should be aware of the declining level of Alcova Reservoir and take proper
precautions.


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 Power Plant is located just downstream of Alcova
Dam and has two 20.7 megawatt generating units.
