Mountain Park Dam, Mountain Park Project, forms Tom Steed Reservoir, and regulates natural flows of West Otter Creek and diverted flows from Elk Creek to provide municipal and industrial water supplies for the cities of Altus, Snyder, and Frederick, Oklahoma. The water is conveyed from the reservoir to the cities through an aqueduct system that consists of 40 miles of pipeline, two pumping plants, and other facilities. The lake is approximately 6,400 acres of open water. Accessible from numerous roads. Several boat ramps and camping facilities. Predominate species include crappie, walleye, hybrid striped bass, and saugeye. Fishing permitted throughout the year.
