Summary
Completed in 1964, this Earth dam stands at a height of 20 feet with a length of 925 feet, providing a storage capacity of 126 acre-feet for recreational purposes. The dam is regulated, permitted, inspected, and enforced by the South Carolina Department of Health and Environmental Control (DHEC), ensuring its safety and compliance with state regulations.
With a hazard potential rated as high and a fair condition assessment, Stills Pond Dam poses a moderate risk (rating of 3) that necessitates regular inspections every two years. Despite its functional spillway type being listed as uncontrolled, the dam continues to serve its primary purpose of recreation, offering a surface area of 17 acres for outdoor activities. The dam's emergency action plan status, risk management measures, and inundation maps preparation remain unlisted, suggesting a potential area for improvement to enhance safety and emergency response protocols for this water resource.
Stills Pond Dam serves as a vital recreational spot in South Carolina, providing a serene environment for water enthusiasts to enjoy various outdoor activities. As a privately owned structure, it plays a crucial role in water resource management and regulation, ensuring the safety and well-being of the surrounding community. With a focus on continuous monitoring and risk assessment, efforts to enhance emergency preparedness and management measures will further strengthen the resilience and sustainability of this important dam structure in the face of changing climate conditions.

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.
