Foss Reservoir, also known as Foss Lake, is in Custer County, Oklahoma on the Washita River, about 15 miles (24 km) west of Clinton, Oklahoma. The reservoir was constructed during 1958–1961 by the U. S. Bureau of Reclamation. The project was known originally as the Washita Basin Project. The lake and dam were named for the community of Foss, Oklahoma, about 6 miles (9.7 km) south of the site. Their primary purpose is to regulate flow of the river and to provide water for the cities of Bessie, Clinton, Cordell and Hobart.[2] It is western Oklahoma's largest lake[3] and lies entirely within Foss State Park.
