Summary
Standing at a height of 12 feet and with a length of 420 feet, the dam has a storage capacity of 139 acre-feet and covers a surface area of 12 acres. Despite its age, the dam is in fair condition and is inspected every three years, with the last assessment conducted in May 2020.
Managed by the South Carolina Department of Health and Environmental Control, Knight Millpond Dam presents a significant hazard potential due to its age and design. However, with proper maintenance and monitoring, the dam continues to provide recreational opportunities for the local community. With a designated emergency action plan in place and regular inspections, the dam ensures the safety of its surrounding area and mitigates the risks associated with potential failures.
As a key feature in the local landscape, Knight Millpond Dam serves as a reminder of historical engineering practices and the importance of water resource management in the face of changing climate conditions. Water resource and climate enthusiasts can appreciate the dam's resilience and the efforts made to ensure its continued functionality and safety for both recreational use and environmental preservation in the region.

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.
