Lake Atalanta is a reservoir along Prairie Creek in Rogers, Arkansas, used primarily for recreation, built in 1936 by the Works Progress Administration. The lake is named for Atalanta Gregory, the wife of O.L. Gregory, who donated most of the land that now forms the lake. Lake Atalanta Dam is earthen with rock fill, and is 43 feet (13 m) tall and 910 feet (280 m) long.
