Lake Acworth is a 110 ha artificial lake southwest of the city of Acworth, Georgia. It is in the extreme northwestern part of Cobb County. The lake impounds Proctor Creek (not the same as Proctor Creek in nearby Atlanta) and Butler Creek. It outflows into Lake Allatoona. The low dam is at the point where State Route 92 (Lake Acworth Drive) crossed over prior to 2023. The lake was formed by a 48-foot-wide concrete dam that was built by the US Army Corps of Engineers in 1950, during the construction of Lake Allatoona. A detailed, video-recorded oral history of the lake’s creation and the federal/state/ocal politics which played a part in its formation is available from the Save Acworth History Foundation via YouTube.
