Atha Dam, located in Gwinnett, Georgia, is a private earth dam completed in 1955 for primarily recreational purposes along the Tr- Yellow River. With a height of 31 feet and a length of 310 feet, the dam has a storage capacity of 65 acre-feet and a maximum discharge rate of 16 cubic feet per second. Despite being classified as having a low hazard potential, the dam is subject to moderate risk due to its age and lack of recent condition assessments.

Managed by the USDA NRCS, Atha Dam currently does not have an Emergency Action Plan in place or updated emergency contacts. The dam's spillway type is uncontrolled, with a width of 20 feet, and there are no associated locks or outlet gates. While the dam's overall risk level is moderate and its condition assessment is not available, it serves as an important recreational resource for the community of Milstead. Enthusiasts interested in water resource management and climate resilience may find Atha Dam's historical significance and operational details intriguing.
