Kelly Barnes Dam was an earthen embankment dam on Toccoa Creek in Stephens County, Georgia, United States, just outside the city of Toccoa. Heavy rainfall caused it to collapse on November 6, 1977, and the resulting flood killed 39 people and caused $2.8 million in damage.
Discharge from the dam averaged 6,286 cubic feet per second (178.0 m 3 /s), over the 31-year period of observation from 1929 to 1960. [5] Discharge rates over the course of a given year vary considerably with seasonal changes in rainfall, within the 4,670-square-mile (12,100 km 2) drainage area of Chattahoochee River system supplying water to the dam.
