Summary
Standing at 15 feet high and spanning 450 feet in length, this dam holds a storage capacity of 51.2 acre-feet and covers an area of 8 acres. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) and undergoes regular inspection and enforcement measures to ensure public safety.
Despite its low hazard potential, Perrow Pond Dam has been rated as being in poor condition as of the last inspection in 2017. The dam's emergency action plan (EAP) status is unclear, and there is no current risk assessment or management plan in place. With the dam's location on TR-Halfway Swamp Creek, it is crucial for stakeholders and authorities to address the dam's condition and develop a comprehensive EAP to mitigate any potential risks and ensure the safety of the surrounding community.
As a significant structure in the Savannah District, Perrow Pond Dam's condition and maintenance are essential factors in preserving water resources and protecting against potential climate-related challenges. With its association with recreational activities and its impact on the local ecosystem, it is imperative for all relevant parties to work together to address the dam's condition, update its emergency preparedness measures, and prioritize its long-term sustainability for the benefit of both the community and the environment.

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.
