Summary
Situated on Black Creek offstream, the dam boasts a low hazard potential and has not been rated for condition assessment as of its last inspection in November 2017.
Managed by the South Carolina Department of Health and Environmental Control, City Sew Disp Dam is subject to state regulation, permitting, inspection, and enforcement. Despite its modest surface area of 18 acres, the dam plays a crucial role in water resource management in the region, with a normal storage level of 90 acre-feet. With no associated structures and no spillway type specified, the dam's risk assessment and emergency action plan status remain unknown, highlighting areas for further evaluation and potential enhancement of safety measures.
For water resource and climate enthusiasts, City Sew Disp Dam offers a fascinating case study in local dam infrastructure and management practices. With its unique design features, regulatory oversight, and storage capacity, the dam serves as a reminder of the importance of maintaining and monitoring critical water structures to ensure public safety and environmental sustainability. As efforts continue to assess and improve the dam's condition and emergency preparedness, the ongoing story of City Sew Disp Dam provides valuable insights into the intersection of water resources, infrastructure resilience, and community safety in the face of evolving climate challenges.

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.
