Summary

Built in 1958, this Earth-type dam stands at 16 feet tall and spans 300 feet in length, with a storage capacity of 150 acre-feet. The primary purpose of the dam is for recreation, offering a surface area of 19 acres for various water activities.

Despite its low hazard potential, Mill Pond Dam is currently in poor condition, as reported during its last inspection in November 2017. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), with the state being responsible for permitting, inspecting, and enforcing regulations regarding its operation. The dam poses a low risk of failure, but its poor condition indicates a need for maintenance and potentially a rehabilitation plan to ensure its long-term safety and functionality.

For water resource and climate enthusiasts, Mill Pond Dam serves as a significant recreational site in South Carolina, providing opportunities for boating, fishing, and wildlife observation. Its location within the Savannah District and its association with the TR-Cypress Creek make it a valuable asset for the local community and a point of interest for those interested in water management and dam safety. As efforts continue to improve the condition of the dam, its role in providing recreational opportunities while safeguarding against potential risks remains a priority for stakeholders and regulators alike.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
