Summary

The dam, constructed with earth and stone materials, reaches a height of 35 feet and spans 325 feet in length, creating a storage capacity of 180 acre-feet and covering an area of 12 acres when filled. Situated on TR-ROCKY CREEK within the Charleston District, the dam is under state regulation and inspection by SC DHEC to ensure its safety and compliance with standards.

Despite its fair condition assessment and high hazard potential, Huntington Lake Dam remains a popular destination for water resource and climate enthusiasts seeking outdoor recreation. With its strategic location and serene surroundings, the dam offers opportunities for activities such as fishing, boating, and wildlife observation. The dam's emergency action plan is periodically reviewed, and its maintenance and monitoring ensure the safety of nearby communities in the event of a potential hazard. Enthusiasts can appreciate the blend of nature and infrastructure at Huntington Lake Dam, making it a must-visit spot for those interested in water resources and climate resilience.

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.
