Keystone Lake

Keystone Lake is a reservoir in northeastern Oklahoma on the Arkansas and Cimarron rivers. It is located upstream about 23mi from Tulsa. It was created in 1968 when the Keystone Dam was completed. The primary purposes are: flood control, hydroelectric power generation, wildlife management and recreation.General descriptionKeystone Lake is about 23600acre in area, and was designed to contain 505381acre.ft of water. It was named for the community of Keystone, which existed on the site from 1900 until 1962, when it was inundated by the waters of the lake. Construction of the lake forced the relocation of three other towns: Mannford, Oklahoma (also known as New Mannford by locals), Prue (also known as New Prue), and Appalachia Bay, Oklahoma. The town of Osage was partially abandoned to the lake, while the rest clings to the south shore. Engineers built a levee around low-lying areas of the south and east sides of Cleveland, Oklahoma to prevent flooding of that city. The shoreline extends for 330mi.Two Oklahoma state parks, Keystone State Park and Walnut Creek State Park, are located along the shores of the lake offering camping, hiking and biking trails, fishing, swimming and boating opportunities. The area also features a Yogi Bear's Jellystone Park Camp-Resort as you cross the Keystone Dam near Sand Springs.
