Black Canyon Reservoir is formed by Black Canyon Diversion Dam, a part of the Boise Project. Managed by the Bureau of Reclamation, this 1,100-acre reservoir offers 12 miles of shoreline. Boating and fishing are the major recreational activities at the reservoir, which is located northeast of Emmett in southwest Idaho. This site offers restrooms, boat ramps, camping, parking, picnic tables, swimming, and accessible facilities for fishing.
