Basin Description: Surface-Water Hydrology
The Chattahoochee and Flint River basins in Georgia contain most of the headwater watersheds for surface waters that flow into or are used by the Florida and Alabama parts of the basin. This section describes the hydrology of the Chattahoochee, Flint, and Apalachicola River basins. Throughout the ACF River basin, low flows usually occur from September to November and peak flows usually occur from January to April when rainfall is high and evapotranspiration is low.
