Sweetwater Creek is a 45.6-mile-long (73.4 km) stream in the U.S. state of Georgia, west of Atlanta. It begins in southwestern Paulding County, flowing generally eastward into southwestern Cobb County, then turning south into eastern Douglas County. It is a tributary of the Chattahoochee River, and near its end it is the centerpiece of Sweetwater Creek State Park. Sweetwater Creek was named after AmaKanasta (Sweet Water), a Cherokee chieftain. The previous record flood was 20 feet (6.1 m) in July 1916. Base flow is around 2.7 feet (0.82 m).
