Bretch Diversion Dam is located on Elk Creek in Kiowa County about 24 miles northeast of Altus, Oklahoma, and about 15 miles northwest of Mountain Park Dam. The dam diverts flows from Elk Creek into Bretch Canal for conveyance into Tom Steed Reservoir by way of Noname Creek and West Otter Creek.
This concrete diversion structure has canal headworks and a concrete wing wall on the left abutment, stream control gates in the center section, and a rolled earthfill dike extending from the concrete structure across the flood plain 5,200 feet to the right abutment. The canal headworks include trashracks at the five-bay intake, and an 18-foot-square radial gate for controlling flows into Bretch Canal, which is designed for a flow of 1,000 cubic feet per second.
The stream control gates include two 27- by 21-foot spillway radial gates, one 10- by 21-foot sluiceway radial gate, and one 24-inch-diameter bypass gate.
The rolled earthfill dike across the flood plain to the right abutment contains a low grass-covered section which provides an overflow spillway with a crest length of 3,620 feet.
