Summary
Completed in 1960, this structure boasts a height of 17.8 feet and a storage capacity of 287 acre-feet. With a low hazard potential and moderate risk assessment, the dam's condition remains unrated, indicating a need for further evaluation to ensure its continued safety and functionality.
While the dam has not been state-regulated, regular inspections are conducted to monitor its structural integrity. The last recorded inspection took place in June 2014, with an inspection frequency of five years. With uncontrolled spillways and outlet gates, the dam's emergency action plan status and risk management measures are currently unlisted, potentially warranting attention to enhance preparedness and mitigate risks associated with its operation.
Water resource and climate enthusiasts intrigued by Griffin Lake Dam's unique features, such as its buttress core type and uncontrolled spillway, may find opportunities for further exploration and study. As a vital component of the local landscape in Thomas County, Georgia, this dam serves as a recreational hub and reservoir, highlighting the importance of responsible management and maintenance to uphold its safety and environmental impact for future generations.

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.
