Antelope Flat Reservoir

Antelope Flat Reservoir is an impoundment located in the southern part of the Maury Mountains in Crook County, Oregon. It is formed by a 33-foot (10 m) high earth-fill dam built across Bear Creek for irrigation purposes. The western part of the lake is within the Ochoco National Forest. Though it covers 170 acres (69 ha) when full, and has a storage capacity of almost 2,000 acre feet (2,500,000 m3) with a maximum depth of 28 feet (8.5 m) and average depth of 11 feet (3.4 m), the reservoir is often not filled to capacity, especially late in the irrigation season.[1] The lake resides at an elevation of 4,984 feet (1,519 m).[2] A boat-launch ramp is located at the lake's western end, and a 25-unit campground lies just up the hill from there.
