The Apalachicola-Chattahoochee-Flint River Basin in Georgia exemplifies a place where many water uses are in conflict, and future climate change is expected to exacerbate this conflict.47f6b2ff-a48f-4b48-899d-a901424bf5b2 The basin drains 19,600 square miles in three states and supplies water for multiple, often competing, uses, including irrigation, drinking water and other municipal uses, power plant cooling, navigation, hydropower, recreation, and ecosystems. Under future climate change, this basin is likely to experience more severe water supply shortages, more frequent emptying of reservoirs, violation of environmental flow requirements (with possible impacts to fisheries at the mouth of the Apalachicola), less energy generation, and more competition for remaining water. Adaptation options include changes in reservoir storage and release procedures and possible phased expansion of reservoir capacity.47f6b2ff-a48f-4b48-899d-a901424bf5b2 7259bc2b-d0aa-460b-b37a-79a11a386e00 412047fe-33cf-49b8-b714-f1a7b096cd43 Additional adaptation options could include water conservation and demand management.
