Summary
With a height of 26 feet and a storage capacity of 43 acre-feet, this dam plays a vital role in flood control and water supply management in the region. Despite its low hazard potential, the dam's condition assessment in 2017 revealed poor maintenance, signaling a need for immediate attention to ensure its structural integrity and long-term functionality.
Located within the jurisdiction of multiple USACE districts, including Nashville, Savannah, and Wilmington, Harry Hill Pond Dam serves as a key piece of infrastructure in Congressional District 04, South Carolina. However, the lack of specified primary owner types and purposes for the dam raises questions about its funding, design, and operational responsibilities. The last inspection in 2017 highlighted the need for regular maintenance and risk management measures to address the deteriorating condition of the dam and mitigate potential hazards.
As water resource and climate enthusiasts monitor the state of Harry Hill Pond Dam, it becomes evident that collaborative efforts between state and federal agencies are essential to ensure the safety and effectiveness of this critical infrastructure. With a history of poor condition assessment and a frequency of inspections every five years, stakeholders must prioritize the implementation of maintenance and emergency preparedness measures to safeguard the surrounding communities and water resources. Additionally, the development of risk assessment protocols and inundation maps can enhance the dam's resilience to changing climate patterns and mitigate potential risks in the future.

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.
