Summary
With a dam height of 32 feet and a length of 850 feet, the earth-type dam serves the primary purpose of flood risk reduction, with a storage capacity of 3,800 acre-feet. The dam is state-regulated by SC DHEC and undergoes regular inspections, with a hazard potential rated as low and a fair condition assessment as of April 2017.
Managed by a local government and a private entity, this dam plays a crucial role in protecting the surrounding area from flooding events. Despite its low hazard potential, the risk assessment for this dam is rated as very high, emphasizing the importance of ongoing monitoring and maintenance. With an associated risk management plan yet to be fully developed, there is a need for continued efforts to ensure the safety and effectiveness of this essential water resource infrastructure for the community and the environment. The involvement of various agencies, including the Natural Resources Conservation Service, highlights the collaborative effort in managing and maintaining this vital dam structure.

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.
