River Overflow
While river floods can happen at any time of year in Georgia, historically, the most common time for them to occur is between January and April, with the majority occurring in March. With 21 river locations in Georgia including the Chattahoochee,Suwannee and Oconee which flows through Athens and southwest for approximately 265 miles joining the Ocmulgee to form the Altamaha River, an estimated 1,170 river floods occurred between 1975 and 2006 alone.
