Sardis Lake in southeastern Oklahoma is located just north of Clayton. Sardis Lake has 117 miles of shoreline and 14,360 surface acres. The lake is an impoundment of Jackfork Creek, a tributary of the Kiamichi River.
In 1977 the U.S. Army Corps of Engineers, began construction of the dam under a contract with the state of Oklahoma for the purpose of selling water to municipalities and industrial customers in Oklahoma. In early 2010, Oklahoma City claims to have bought the rights to 90% of the water in Sardis Lake, but the Choctaw Nation, which was not involved in the transaction, believes the city does not have the right to purchase the water and the state had no right to sell the water rights.
