"The Great Lakes and Ohio River Division Water Management Team of the U.S. Army Corps of Engineers (USACE) is responsible for reducing water level stages along the lower Ohio and middle Mississippi Rivers during significant flood events. To accomplish our mission, we direct the flow releases from Barkley Lake on the Cumberland River and issue regulation instructions to the Tennessee Valley Authority for the operation of Kentucky Lake on the Tennessee River. An effective management tool in coordinating the reservoir releases is a dynamic, one-dimensional unsteady flow model called 'Cascade'. Cascade routes Ohio River and upper Mississippi River flows to determine the impact of reservoir releases on flood levels. We present an overview of our water management operations, the complex issues and constraints, and Cascade. We conclude with a summary of recent past flood operations."
