Summary
Completed in 1967, this earth dam stands at a height of 34 feet and stretches 600 feet in length, creating a recreational reservoir with a storage capacity of 123 acre-feet. The dam's primary purpose is for recreation, providing a surface area of 9 acres for enthusiasts to enjoy activities such as fishing, boating, and wildlife observation.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), Mattox Pond Dam is state-regulated, with regular inspections ensuring its fair condition and low hazard potential. Despite its fair condition assessment, the dam poses a moderate risk level, prompting the need for effective risk management measures. With a controlled spillway type and uncontrolled spillway width, the dam's emergency action plan status and inundation maps preparedness are currently unspecified.
Located on TR-Abingdon Creek and overseen by the Charleston District of the US Army Corps of Engineers, Mattox Pond Dam serves as a vital water resource for the local community, offering both recreational opportunities and a source of water storage. As water resource and climate enthusiasts, it is essential to stay informed about the condition and management of dams like Mattox Pond to ensure their continued safety and sustainability for future generations.

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.
