Completed in 1972, this earthen dam backs up the waters of the Caddo River some 27 miles creating DeGray Lake. The history of the Caddo River goes back hundreds of years to the first settlers in the area – the Caddo Indians. Although recreation plays a major role in every day activity, hydropower makes this lake one of the most efficient and energy producing projects in the South. DeGray Lake holds the distinction as the first “pump back capable” impoundment in the history of the Corps of Engineers.
