The Chattahoochee River runs from the Chattahoochee Spring in the mountains of northeast Georgia, southwestward past Atlanta and through its suburbs, then turns southward to form the southern half of the Georgia/Alabama state line. Further south it merges with the Flint River at Lake Seminole near Bainbridge 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 zone
Several lakes, including Lake Lanier, Lake George, West Point Lake, and others are controlled by the U.S. Army Corps of Engineers, providing hydroelectricity, flood control, drinking water, recreation, and navigation. The Georgia Power Company also has a series of dams along the middle portion of the river between West Point Lake and Lake Walter F. George. Several smaller and older lakes and dams also provide these services on a much smaller and more localized scale, including Bull Sluice Lake, which is held by Morgan Falls Dam. This dam was built by the Georgia Railway and Power Company in 1902 to provide electric power to the Atlanta trolley system.
At various points, it serves as the border between several counties and cities, as well as forming a significant part of the border between the states of Alabama and Georgia.
Within Georgia, it divides:
- Habersham County and White County
- Forsyth County and Gwinnett County
- Fulton County (the part that was formerly Milton County) and Gwinnett County
- Formerly: Milton County and Fulton County
- Cobb County and Fulton County
- Douglas County and Fulton County
- Carroll County and Fulton County
- Carroll County and Coweta County
Unusually, Atlanta is built on a ridge rather than on the river, which has kept much of the natural scenic beauty of the section that runs through metro Atlanta. This is so much so that the Chattahoochee River National Recreation Area, spread across several disconnected units, protects many of the riverbanks north of the city.
The non-profit organization Upper Chattahoochee Riverkeeper is a watchdog group for the northern half of the river.
Controversy has come to the river very recently because of the enormous growth of metro Atlanta, and the tremendous increase in water withdrawals from the river. Oysters in Apalachicola Bay depend on the brackish water mix and alternating freshwater and saltwater flows which the river and tides provide. Interbasin water transfers also occur, where water is withdrawn from the Chattahoochee, but then discharged as treated sewage into another river, such as Hall County's Oconee River. The U.S. Congress has been asked to intervene to put navigation of the lower Chattahoochee (south of Columbus, Georgia) by barges last on the priority list, as most people view this as a complete waste of water during droughts, and a tremendous aggravation to the fight between Georgia, Florida, and Alabama over rights to the river. The case is now in court, and may take years to resolve.

[edit] Flooding
The most recent major flood along the river occurred in September 2004, as a result of Hurricane Ivan (which came on the heels of Hurricane Frances).[1] At Vinings at the northwestern Atlanta city limit, it rose to 22.6 feet or 6.9 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.[2] 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.
