Barkley Lake, KY

Lake Barkley, a 58,000-acre (230 km2) 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 miles (61 km) 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 miles (80 km), with the Land Between The Lakes National Recreation Area located between them.

Lake Barkley is 134 miles (216 km) long with a shoreline measuring 1,004 miles (1,616 km). The lake's level is maintained at different levels throughout the year for flood control purposes. Summer pool, 359 ft (109 m) above sea level, is normally reached by May 1. The water level begins dropping gradually on July 1, and winter pool (354 ft/107 m) is reached by December 1. The spring rise starts April 1. The lake's water surface area varies accordingly from 57,920 acres (234 km²) at summer pool to 45,210 acres (183 km²) at winter pool.

The water temperature average is 45 to 65 during winter months and 70 to 80 during the summer months.  Personal watercraft are permitted.  This is a popular boating and recreation lake adjacent to Kentucky Lake.
