Summary
Constructed in 1946, this earth dam stands at 19 feet tall and spans 455 feet in length, providing a storage capacity of 218 acre-feet and a surface area of 25 acres. The dam is situated on Hunter Branch, under the regulatory oversight of the South Carolina Department of Health and Environmental Control (SC DHEC), ensuring regular inspections and enforcement of safety measures.
Despite being rated as having a fair condition assessment, Longleaf Plantation Dam carries a high hazard potential, emphasizing the importance of ongoing monitoring and risk management. The dam's Emergency Action Plan (EAP) status and adherence to guidelines remain unspecified, highlighting the need for continued preparedness and communication protocols in case of emergencies. With Congressman Joe Wilson representing the area in Congress and the Savannah District of the US Army Corps of Engineers overseeing operations, Longleaf Plantation Dam stands as a significant structure for both water resource management and climate enthusiasts in the region.

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.
