Allatoona Lake is the water source for the Wyckoff WTP and is a recreational attraction to more than six million visitors each year. Allatoona Lake is owned and managed by the U.S. Army Corps of Engineers. The lake covers more than 12,000 acres and is within the Etowah River Basin. CCMWA purchased storage in Allatoona Lake in 1963 under the Water Supply Act. Releases from Allatoona Lake into the Etowah eventually make their way into the Coosa and Alabama Rivers into the Gulf of Mexico at Mobile, Alabama.
