High Quality Content by WIKIPEDIA articles! Kentucky Dam is a hydroelectric dam on the Tennessee River on the county line between Livingston County and Marshall County in the U.S. state of Kentucky. The dam is the lowermost of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s and early 1940s to improve navigation on the lower part of the river and reduce flooding on the lower Ohio and Mississippi rivers. The dam impounds the Kentucky Lake of 160,000 acres (65,000 ha), which is the largest of TVA`s reservoirs and the largest artificial lake by area in the Eastern United States. A canal connects Kentucky Lake to nearby Lake Barkley, created by Barkley Dam on the Cumberland River. The lakes run parallel for more than 50 miles (80 km), with the Land Between the Lakes National Recreation Area located between them.
