is a city in Lyon County, Kentucky, United States. The population was 596 at the 2000 census.
Lake Barkley was formed in the early 1960s when a dam was constructed on the Cumberland at Grand Rivers. Two communities with a combined population of 3500 rested on the banks of the Cumberland. When the river was impounded, or flooded by the dam, the two towns - Eddyville and Kuttawa - had to be relocated. Now, these two towns literally run through Lake Barkley.
