Summary
The dam stands at a height of 29 feet and has a length of 250 feet, creating a pond with a storage capacity of 108 acre-feet. Despite its low hazard potential, the dam is currently in poor condition as of the last inspection in 2017, signaling a need for maintenance and repairs.
Managed by the South Carolina Department of Health and Environmental Control (SC DHEC), Wrenn Farms Pond Dam is subject to state regulation, permitting, inspection, and enforcement. The dam impounds water from the Rock Water Spring Branch and has an uncontrolled spillway type. With a moderate risk assessment rating, it is essential for the owner to address the poor condition of the dam to ensure the safety of the surrounding community and the longevity of the structure.
While Wrenn Farms Pond Dam may be primarily used for recreation, its significance extends beyond leisure activities. As a vital water resource in the region, it is crucial to prioritize the maintenance and rehabilitation of this dam to mitigate potential risks and ensure the sustainability of its functions for the future.

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.
