ACF River Basin

It is located in the South Atlantic-Gulf Water Resource Region, which is listed as HUC 03.

[1][5] Georgia has also lobbied the United States Congress to end navigation on the Appalachicola and lower Chattahoochee, to conserve more water during droughts.

Keeping the two rivers at a navigable depth during these times requires large releases from dams upstream, sending potential drinking water downstream for shipping, and often dropping lakes to levels dangerous to boaters.

Other ecological conservation and economic concerns include protecting harvests of oysters in Apalachicola Bay, which require a large enough flow of fresh water to prevent excessive saltwater intrusion from the Gulf.

[6] Numerous endangered and imperiled species occur in the basin, including many endemic mussels [7] The cost of dredging silt, much of it caused by uncontrolled growth across metro Atlanta's fine red clay soil, has also been criticized as a wasteful exercise to float so little ship traffic.
