Summary
Completed in 1932, this Earth-type dam stands at a height of 14 feet and stretches 535 feet in length, creating a reservoir with a storage capacity of 52 acre-feet. The primary purpose of Riggs Pond Dam is for recreation, providing a surface area of 8 acres for visitors to enjoy various water activities.
Despite its low hazard potential, Riggs Pond Dam has been assessed as being in poor condition as of October 2017. The dam is state-regulated and regularly inspected by the South Carolina Department of Health and Environmental Control to ensure public safety. With a moderate risk assessment rating, it is crucial for ongoing risk management measures to be implemented to address any potential safety concerns and maintain the dam's structural integrity.
Surrounded by the tranquil waters of TR-Bennetts Branch, Riggs Pond Dam offers a picturesque setting for water resource and climate enthusiasts to explore. As one of the many dams in South Carolina contributing to water conservation and recreational opportunities, Riggs Pond Dam serves as a reminder of the importance of proper maintenance and oversight to ensure the safety and sustainability of our water resources.

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.
