The Flint River is an approximately 150 miles (240 km) long river, in the U.S. state of Georgia. The river drains 8,460 sq mi of western Georgia, flowing south from the upper Piedmont region south of Atlanta to the wetlands of the coastal plain in the southwestern corner of the state. Along with the Apalachicola and the Chattahoochee, it forms part of the ACF basin. In its upper course through the red hills of the Piedmont it is considered especially scenic, flowing unimpeded for over 200 miles.

Natural History

The river is considered to have three distinct sections as it flows southward through western Georgia. In its upper reaches in the red hills of the Piedmont, it flows through a deeply incised channel etched into crystalline rocks. South of its fall line near Culloden, the channel transforms to a broad, forested swampy flood plain. South of Lake Blackshear, it transforms again, flowing through a channel in limestone rock above the Upper Floridan Aquifer below southwestern Georgia and northwestern Florida.

The river has been prone to floods throughout its history. In 1994, during flooding from Tropical Storm Alberto, the river crested at 43 feet in Albany, resulting in the emergency evacuation of over 23,000 residents, and creating one of the worst natural disasters in the state's history. Interstate 75 was closed in Macon, and Albany State University was also seriously flooded, as the river became a few miles or several kilometers wide in some places. The water lifted caskets from cemeteries and left them along with drowned cattle and other livestock stuck in trees and other places. Other significant floods occurred in 1841 and 1925.

In January 2002, a winter storm blew through Atlanta the day after New Year's Day, and deicing fluid leaked into the river when the airport's drainage system overflowed. Nobody became seriously ill from the antifreeze, which made it into drinking water for some, but the airport changed the system to avoid the problem in the future. This has not been tested yet, however, since even as of 2007, this was the last major snow event the city had seen due to several warm or dry winters.
