Park Reservoir (Wyoming)

Park Reservoir is a high-altitude lake tucked away in the Bighorn Mountains of northern Wyoming. It sits at an elevation of roughly 8,268 feet (2,520 m) within the Bighorn National Forest. The reservoir is primarily used for irrigation, storage, and recreation. Park Reservoir feeds Big Goose Creek, which is the town of Sheridan, Wyoming's primary water supply. The reservoir is located roughly 20 miles south of Sheridan, straddling the boundary between Sheridan and Johnson counties. Access is primarily via Red Grade Road (State Highway 26), a steep, unpaved route that originates near the town of Big Horn. The reservoir has a capacity of 12,500 acre-feet.
