ACF River Basin Drought Early Warning System
The Apalachicola-Chattahoochee-Flint (ACF) River Basin covers over 12 million acres of watershed across Georgia, Alabama and Florida. With its headwaters in Georgia, the ACF Basin terminates in the Apalachicola Bay along the coast of Florida’s panhandle. Water in the ACF Basin meets a range of needs, including, but not limited to, municipal and industrial water supply, agricultural irrigation, hydroelectric generation and thermoelectric cooling, and environmental and instream flows. Metropolitan Atlanta, with a population of more than 5 million, relies upon Lake Lanier and the Chattahoochee River for approximately 70% of its water supply. In December 2009, recurring droughts led the NIDIS to select the ACF Basin as a high priority for developing a DEWS in the Southeastern United States, largely because of the breadth and complexity of the Basin’s ongoing water management challenges.
Upcoming in 2020: An Expanded Southeast DEWS
The U.S. Southeast region is increasingly experiencing record-breaking droughts that can develop rapidly. Recognizing a need to improve drought early warning across the full geographic footprint of the Southeast, and in response to requests from regional stakeholders, the National Integrated Drought Information System (NIDIS) plans to develop a Southeast Drought Early Warning System (DEWS). This Southeast DEWS will build on the partnerships and successes from the ACF River Basin and Coastal Carolinas DEWS, while expanding to include the full geographic footprint of Florida, Alabama, Georgia, South Carolina, North Carolina, and Virginia.
