Summary
Completed in 1964, this earth dam stands at 49 feet high with a hydraulic height of 43 feet, providing essential flood risk reduction for the surrounding area. With a storage capacity of 7,460 acre-feet and a normal storage capacity of 3,120 acre-feet, this dam plays a vital role in managing water resources and protecting the local community from potential hazards.
The dam's high hazard potential underscores the importance of regular inspections and maintenance to ensure its structural integrity. Despite the satisfactory condition assessment in 2017, the dam's hazard potential and moderate risk assessment (level 3) highlight the need for ongoing risk management measures and emergency preparedness. Managed by the Georgia-SAFE DAMS program, this state-regulated dam serves as a key asset in water resource management, reflecting a commitment to environmental stewardship and climate resilience in the face of changing weather patterns and increasing water-related risks in the region.
As a focal point for water resource and climate enthusiasts, Fort Yargo Lake State Park Dam stands as a testament to the critical role of infrastructure in safeguarding communities and ecosystems. With its uncontrolled spillway and buttress core design, this dam exemplifies the intersection of engineering innovation and environmental protection. By understanding and appreciating the importance of structures like Fort Yargo Lake State Park Dam, enthusiasts can deepen their knowledge of water management strategies, climate adaptation efforts, and the interconnectedness of human activities with natural systems in a rapidly changing world.

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.
