Summary
Built in 1965, this Earth dam stands at a structural height of 30 feet and a hydraulic height of 24 feet, providing a surface area of 90 acres for water activities and a normal storage capacity of 1882 acre-feet. Managed by the NC Dam Safety Program, the dam is inspected regularly, with the last assessment in February 2021 indicating a fair condition.
Situated in the Manchester area along the Reedy Swamp, Lake Carolina offers a scenic spot for recreation and water supply. With a high hazard potential, the reservoir's emergency action plan dates back to 2009, ensuring preparedness for any unforeseen events. The dam's maximum discharge capacity of 166 cubic feet per second emphasizes the importance of proper maintenance and regulation to safeguard the surrounding communities.
Water resource and climate enthusiasts can appreciate Lake Carolina not only for its functional aspects but also for its contribution to the local ecosystem. As a vital water source for irrigation and recreation, this reservoir serves as a significant example of sustainable water management in North Carolina. With ongoing inspections and a commitment to safety, Lake Carolina stands as a testament to the importance of maintaining and regulating water resources for both human and environmental well-being.

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.
