William S. Key Correctional Center is approximately 13 miles north of Woodward and 1 mile east of Fort Supply. Named for former U.S. Army General, Oklahoma State Penitentiary Warden and prominent business-man William Shaffer Key, the minimum-security facility opened in 1988 and has a 1,105-inmate capacity.
The facility covers approximately 3,200 acres, which includes Agri- Services and the Fort Supply Historical Site.
The Oklahoma Historical Society occupies part of the east side of the facility. The prison is also the site of historic Fort Supply, where soldiers would stock up on provisions before heading west to fight the Southern Plains Indians.
