Built in 1946, this earth dam on Spring Creek serves primarily for irrigation purposes in Carbon, Wyoming. With a height of 40 feet and a length of 610 feet, Sheep Mountain has a storage capacity of 438 acre-feet and a surface area of 35 acres.
Despite its low hazard potential, Sheep Mountain's condition assessment is rated as poor, with the last inspection conducted in September 2020. The dam's spillway is uncontrolled, and it has one valve outlet gate. While it has a moderate risk rating of 3, the dam is state-regulated and routinely inspected, meeting guidelines for emergency action preparedness. With its stone core and soil foundation, Sheep Mountain stands as a testament to early 20th-century irrigation infrastructure in the region, showcasing the intersection of water resource management and climate adaptation efforts.
