Summary
Completed in 1975, this earth dam stands at a height of 11 feet and spans a length of 2905 feet, with a storage capacity of 198 acre-feet. Situated on Tawcaw Creek offstream, the dam serves a primary purpose that is classified as "Other," with a low hazard potential but a poor condition assessment as of October 2017.
Despite its poor condition assessment, the Summerton Water Tr Dam continues to be regulated by the South Carolina Department of Health and Environmental Control (SC DHEC), with state permitting, inspection, and enforcement processes in place. The dam is under state jurisdiction and is subject to regular inspections, with the last one conducted in October 2017. While the dam is deemed to have a low hazard potential, its condition assessment suggests that maintenance and potential rehabilitation may be necessary in the near future to ensure its continued effectiveness in water resource management and climate resilience efforts in the region.
For water resource and climate enthusiasts, the Summerton Water Tr Dam represents a vital piece of infrastructure in Clarendon, South Carolina. With its earth construction and buttress core type, the dam plays a crucial role in managing water storage and flow in the area, contributing to flood control and water supply management. While its condition assessment is concerning, ongoing regulatory oversight and potential risk management measures can help ensure the dam's continued functionality and safety for the surrounding community and ecosystem.

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.
