Allatoona is the oldest multipurpose project in the South Atlantic Division (SAD). It was authorized under the Flood Control Acts (FCAs) of August 18,1941, and December 22, 1944, for the purposes of flood control and hydroelectric generation. The FCA of 1944 also authorized construction of recreation facilities.  Impoundment of the project began in December 1949 and was in full operation by January 1950. The total cost of the Allatoona project for construction, land, clearing and relocation was $31.5 million.  Allatoona was authorized for flood control, hydroelectric power generation, water supply and water quality, recreation and fish and wildlife management. The Allatoona project has an 1,110 square mile drainage area. This is the first impoundment for water as it flows from the Blue Ridge Mountain region, and additional water for the project depends on rainfall.  Responsible stewardship of the lake and surrounding 25,000 acres of public lands is the highest priority for the staff at Allatoona.

As one of the most frequently visited Corps lakes in the nation, Allatoona provides recreation opportunities for nearly 6 million visitors annually. The Corps and other public and private organizations work together to provide a wide spectrum of quality recreation opportunities.  These opportunities fuel the regional economy by nearly $250 million annually.  As metro Atlanta moves northwest, this usage is certain to increase. The Corps of Engineers has 688 campsites on the lake along with 453 picnic sites. Additional facilities are found in nine city and county parks, one state park and eight commercial marinas.  Allatoona has 270 miles of shoreline on which 978 Shoreline Use permits have been issued.
