Summary
This earth dam, completed in 1920, serves primarily for recreational purposes, with a storage capacity of 117 acre-feet and a drainage area of 1044 acres. The dam stands at 14 feet high with a hydraulic height of 12 feet, spanning a length of 660 feet.
Despite being classified as having a low hazard potential and a moderate risk assessment rating, Graham Pond Dam has not been inspected since September 1988. The dam features an uncontrolled spillway and outlet gates, with no state regulation or permitting in place. While the condition assessment is listed as "not rated," the risk management measures and emergency action plan status remain unknown.
For water resource and climate enthusiasts, Graham Pond Dam offers an intriguing case study in dam safety and recreational infrastructure management. The historical significance of this early 20th-century earth dam, combined with its remote location in the Griffin Lake environs, presents a unique opportunity to explore the intersection of water management, private ownership, and public safety in Georgia's diverse landscape.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
