Lake Barkley, a 58000 acre reservoir in Livingston, Lyon, and Trigg counties in Kentucky and extending into Stewart and Houston counties in Tennessee, was impounded by the U.S. Army Corps of Engineers in 1966 upon the completion of Barkley Dam.
 Both the lake and the dam are named for Vice President Alben Barkley, a Kentucky native.
 The dam impounds the Cumberland River near Grand Rivers, Kentucky, approximately 38 mi upstream from where the Cumberland empties into the Ohio River.
 One mile (1.6 km) above the dam is a canal connecting Lake Barkley with Kentucky Lake, forming one of the greatest freshwater recreational complexes in the country.
 The lakes run parallel courses for more than 50 mi , with the Land Between The Lakes National Recreation Area located between them.
