Mannford is a town in Creek, Pawnee, and Tulsa counties in the northeastern part of the U.S. state of Oklahoma. The population was 2,095 at the 2000 census. A bedroom community of Tulsa sitting on Lake Keystone, this town is known as the Striped Bass Capital of the World. The town nearly became extinct in the early 1960s when the entire town had to move due to the creation of Lake Keystone. Mannford is also known for its bigfoot sightings. Many hunters have been quoted as seeing the apelike creature roaming the landscape.
