Chattahoochee River

The Chattahoochee River runs from the Chattahoochee Spring in the mountains of northeast Georgia, southwestward by Atlanta and through its suburbs, then turns southward to form the southern half of the Georgia/Alabama state line. It then merges with the Flint River at Lake Seminole to form the Florida panhandle's short Apalachicola River, and is the largest part of the ACF River Basin watershed. The name Chattahoochee is thought to come from a Creek word for "painted rock," possibly referring to the many colorful granite outcrops along the northeast-to-southwest segment of the river. Much of this segment of the river runs through the Brevard fault.

Flooding

The most recent major flood along the river occurred in September 2004, as a result of Hurricane Ivan. http://www.srh.noaa.gov/ffc/html/ivanpcpn.shtml At Vinings at the northwestern Atlanta city limit, it rose to 22.60 feet or 6.89 meters late on September 16, far above its flood stage of 14.0 feet or 4.3 meters. Numerous tributaries also swelled far over and beyond their banks. These were the highest levels seen since 1990, and the second highest ever since Buford Dam was built upstream. The National Weather Service in Peachtree City estimated that this was a nearly 100-year flood event. http://www.srh.noaa.gov/ffc/html/pns91704.txt At Helen above the dam, the river rose to 6.8 feet or 2.07 meters, just above the flood stage of 6.0 feet or 1.83 meters.
