2. The Middle ChattahoocheeWater Planning Regionbedrock, typically limestone). The greatest use and recharge of groundwater for theMiddle Chattahoochee Planning Region occurs here. The interaction betweensurface and groundwater in the basin is not fully understood, especially in regard torecharge, connectivity, water quality, lake influence on groundwater levels anddrought effects.Approximately 74 percent of the drainage area of the ACF Basin and 23 percent ofthe ACT Basin are in Georgia 5 . Georgians are highly dependent upon these basinsin a variety of ways. The Chattahoochee River, including Lake Lanier, is the primarysource of water supply for the metropolitan north Georgia region 6 as well as for manyGeorgians downstream. Lake Allatoona and the rivers and streams of the ACT Basinare another major source of water supply to metropolitan Atlanta as well as the Cityof Rome and other communities in Georgia. The ACF Basin in Georgia is a richagricultural region, and Georgia’s farmers rely upon its surface and ground waters forirrigation. The waters of the ACF and ACT Basins support a rich diversity of fish andwildlife species.The federal reservoirs in the ACF and ACT Basins are among the nation’s mostvisited for recreation, and Lake Lanier and West Point Lake alone have beenestimated to contribute well in excess of several billion dollars in annual revenueattributable to recreation. Federal dams and reservoirs also produce hydropower andprovide limited support for commercial navigation7,8 . The region with its waterresources are summarized in Figure 2-1. Dams in the Apalachicola-Chattahoochee-Flint (ACF) are summarized in Table 2-1.05.02.20115 U.S. Army Corps of Engineers, et al., Draft Environmental Impact Statement for the Water AllocationFormula for the ACF River Basin (ACF EIS), September 1998.6 Metropolitan North Georgia Water Planning District, Water Supply and Water ConservationManagement Plan, May 2009.7 U.S. Army Corps of Engineers, Mobile District, http://water.sam.usace.army.mil/recreat.htm.8 Lake Lanier Association, Gainesville, GA, About Lake Sidney Lanier, http://www.lakelanier.org/Georgia State-wide Water Management PlanMIDDLE CHATTAHOOCHEE2-3
