Did Lake Cumberland in Kentucky cover what used to be cities or residential areas?

No, Lake Cumberland in Kentucky did not cover any major cities or residential areas when it was created. The lake was formed by the construction of Wolf Creek Dam on the Cumberland River in 1952, and the area that was flooded to create the lake was primarily rural, consisting of farmland, forests, and small communities. Some communities were relocated or rebuilt higher up on the hillsides to avoid being flooded, but no major cities were submerged.
