Keyhole State Park is a state-operated, public recreation area surrounding the Keyhole Reservoir near the town of Moorcroft in Crook County, Wyoming.[3] The state park features multiple campgrounds, a privately operated marina, and approximately 14,720 acres of water recreation.[4]

The Keyhole Reservoir, an impoundment of the Belle Fourche River, was formed by the Keyhole Dam project of the United States Bureau of Reclamation, completed in 1952. The reservoir has a total capacity of 334,200 acre-feet and water surface of 13,700 acres, which provides storage for irrigation, flood control, fish and wildlife conservation, recreation, sediment control, and municipal and industrial water supply. Although located in Wyoming, the reservoir's waters are allocated by compact to go 90 percent to South Dakota and 10 percent to Wyoming.[5]
