The Fullerton Dam is a ruined dam located 7 miles (11 km) northwest of Olustee, in Jackson County, Oklahoma. Farmer William J. Fullerton built the dam across Turkey Creek in the mid-1890s to irrigate the vegetable crops on his 1,500 acres (610 ha) farm. As western Oklahoma was a dry region, farmers depended on a regular water supply to produce crops, making Fullerton's dam an important innovation.
