Summary
Built in 1969, this Earth-type dam stands at a height of 33 feet and spans a length of 650 feet, with a storage capacity of 630 acre-feet. Despite its relatively low hazard potential, the dam is regulated, inspected, and enforced by the South Carolina Department of Health and Environmental Control (SC DHEC) to ensure its structural integrity and compliance with state regulations.
The dam's satisfactory condition assessment as of November 2019 indicates its resilience and readiness to manage any potential risks or emergencies effectively. While it does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, the dam's low hazard potential and regular inspection schedule contribute to its overall safety and operational efficiency. With a history of compliance and adherence to state regulations, Duke Robinson Ash Pond serves as a reliable and vital component of the water resource infrastructure in the region, supported by the Wilmington District of the US Army Corps of Engineers.
Water resource and climate enthusiasts interested in sustainable water management practices and infrastructure maintenance can find valuable insights in the operational and regulatory framework of Duke Robinson Ash Pond. As a publicly-owned utility structure, the dam plays a crucial role in maintaining water quality and ensuring environmental protection in the region. With its satisfactory condition assessment and low hazard potential, the dam exemplifies the importance of proactive monitoring and compliance with state regulations to mitigate risks and safeguard water resources for future generations.

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.
