Crystal Lake Reservoir, also known as Crystal Lake, is located in Curt Gowdy State Park, approximately 24 miles west of Cheyenne and 24 miles east of Laramie, Wyoming. This 138-acre reservoir sits on Middle Crow Creek within the South Platte sub-basin at an elevation of 6,980 feet on the eastern flank of the Laramie Mountains. Constructed in 1910 and rehabilitated in 1986, the reservoir is approximately 0.90 miles long and 0.47 miles wide with 3.35 miles of shoreline and a storage capacity of 3,410 acre-feet. While some water originates from the Middle Crow Creek drainage, most comes from the Douglas Creek drainage via a gravity-fed pipeline from Rob Roy Reservoir. Crystal Reservoir offers diverse fishing opportunities and is managed by Wyoming State Parks through a lease agreement with the City of Cheyenne. The smaller size and 15 horsepower motor limit make this reservoir an ideal location for anglers seeking a more peaceful fishing experience compared to nearby Granite Reservoir.
