The Reclamation program in Oklahoma emphasizes municipal and industrial water supply. There are six projects with seven major reservoirs in the state, five of them constructed primarily to provide water to cities and towns. They are the Norman, Washita Basin (Foss and Ft. Cobb reservoirs), Arbuckle, Mountain Park and McGee Creek projects. In addition to providing city water, the W.C. Austin Project provided irrigation water to more than 45,000 acres of farmland in 2003. The principal crop is cotton.

In 2003, the Oklahoma projects provided 133,482 acre-feet of municipal and industrial water to 18 cities with a population of approximately 1.4 million. State parks are operated at all of the reservoirs, except Lake of the Arbuckles which is included in the Chickasaw National Recreation Area administered by the National Park Service. Over 4.3 million people visited Reclamation projects in the state in 2003.
