Summary
With a storage capacity of 169 acre-feet of water, this dam serves primarily for recreation purposes, offering visitors a serene setting for outdoor activities. The dam is not state-regulated but undergoes inspections every five years to ensure its safety and functionality.
Although the hazard potential is rated as low, the risk assessment for Riggs Lake Dam (South) is considered moderate, highlighting the importance of ongoing risk management measures. The dam features an uncontrolled spillway and outlet gates, and it has not been modified since its completion. While the condition assessment is currently listed as "Not Rated," the dam's risk profile suggests the need for continued monitoring and maintenance to mitigate potential risks and ensure the safety of the surrounding area.
Located within the Charleston District and under local government ownership, Riggs Lake Dam (South) offers a peaceful retreat for water resource and climate enthusiasts in Georgia. While it may not be a state-regulated structure, its role in providing recreational opportunities and managing water resources underscores its significance in the region. As efforts to address climate change and water resource management continue to evolve, the maintenance and monitoring of dams like Riggs Lake Dam (South) play a crucial role in ensuring the resilience and sustainability of our water infrastructure.

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.
