About this plant
Kentucky Dam is a hydroelectric dam on the Tennessee River on the county line between Livingston and Marshall counties 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. It was a major project initiated during the New Deal of President Franklin D. Roosevelt's administration, to invest in infrastructure to benefit the country. 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. It was designated as an National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1996 and listed on the National Register of Historic Places in 2017.
