Summary
Completed in 1973, this earth dam stands at 54 feet in height and spans 900 feet in length, with a storage capacity of 4805 acre-feet and a surface area of 192 acres. The dam is regulated by the South Carolina DHEC and has been deemed to have a significant hazard potential, although its condition is currently assessed as fair.
Managed by the local government, this dam on Mill Creek is designed by Prather, Thomas, Campbell and Associates, with oversight from the Natural Resources Conservation Service. Despite its uncontrolled spillway and outlet gates, the dam has a history of regular inspections and enforcement to ensure public safety. The risk assessment for this structure is moderate, indicating a need for continued monitoring and potential risk management measures to safeguard the surrounding community and environment. Climate and water resource enthusiasts will find interest in the unique features and management of Jackson-Mill Creek WCD Dam 7, highlighting the importance of effective dam infrastructure in mitigating flood risks and ensuring water supply resilience.

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.
