Summary
Built in 1957, the dam stands at a height of 12 feet and spans 360 feet in length, with a storage capacity of 65 acre-feet. The primary purpose of Denny Pond Dam is for recreation, providing a surface area of 9 acres for water enthusiasts to enjoy.
Despite its recreational appeal, Denny Pond Dam has been flagged for poor condition assessment and significant hazard potential. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), with state permitting, inspection, and enforcement in place. The last inspection conducted in November 2017 highlighted the need for improvements to ensure public safety and environmental protection.
With its proximity to the TR-LYNCHES RIVER and its vital role in providing recreational opportunities, the maintenance and upkeep of Denny Pond Dam are crucial. As a significant structure with a notable hazard potential, efforts to address its poor condition and ensure compliance with regulatory standards are essential to safeguard both the dam's integrity and the well-being of those who utilize its waters for leisure activities.

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.
