The Grand River watershed consists of approximately 12,000 square miles of runoff in parts of Kansas, Missouri and Oklahoma. Of that total, over half—7,000 square miles—is uncontrolled runoff, meaning there is no reservoir to control it above the Pensacola Dam. However, the remaining 5,000 square miles of runoff passes through the John Redmond Dam, located near Burlington, Kansas, prior to reaching the Grand River system in Oklahoma.
