Summary
The dam stands at a height of 25 feet and has a storage capacity of 1691 acre-feet, with a normal storage level of 323 acre-feet. The dam impounds Horse Creek and covers a surface area of 42.6 acres, providing a picturesque setting for outdoor activities.
Despite its fair condition assessment, Flat Rock Pond Dam is classified as having a high hazard potential, highlighting the importance of regular inspections and maintenance. The dam is regulated by the South Carolina Department of Health and Environmental Control, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations. The last inspection in December 2019 revealed the dam's condition as fair, with an inspection frequency of every two years.
With its historic significance and vital role in water resource management, Flat Rock Pond Dam serves as a valuable asset to the local community. As enthusiasts of water resources and climate, understanding the infrastructure and management of dams like Flat Rock Pond Dam is crucial for ensuring the safety and sustainability of water reservoirs 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.
