Summary
Completed in 1955, this earth dam stands at a height of 16 feet and spans a length of 755 feet. It serves primarily for recreational purposes, with a storage capacity of 61 acre-feet and a normal storage level of 29 acre-feet. The dam is situated on the Penn Branch river and is regulated by the South Carolina Department of Health and Environmental Control.
Despite its low hazard potential, the dam's condition assessment is rated as poor, with the last inspection conducted in November 2017. The inspection frequency is set at every 5 years, and emergency action plans have not been prepared or reviewed recently. The dam lacks spillway infrastructure and associated structures, with no outlet gates or locks present. The risk assessment, inundation maps, and risk management measures for the dam remain unspecified, highlighting potential vulnerabilities in the event of a dam failure.
Water resource and climate enthusiasts may find Webber Pond Dam an intriguing site for further exploration into the challenges and opportunities surrounding dam safety and management in South Carolina. With its historical significance and recreational function, the dam presents an interesting case study in balancing human activities with environmental protection. As efforts to enhance dam safety and resilience continue, stakeholders can engage in discussions on sustainable water resource management practices to ensure the longevity and safety of structures like Webber Pond Dam.

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.
