Summary
Completed in 1987, this earth dam stands at a hydraulic height of 19.1 feet and a structural height of 24.2 feet, with a length of 610 feet. It has a normal storage capacity of 37 acre-feet and a maximum storage capacity of 62 acre-feet, covering a surface area of 4.4 acres and serving a drainage area of 68 square miles.
Despite its recreational value, the dam poses a high hazard potential and is currently rated as unsatisfactory in condition assessment. It is regularly monitored and inspected by the North Carolina Department of Environmental Quality's Dam Safety Program, with the last inspection conducted in October 2020. The dam's Emergency Action Plan was last revised in October 2012, highlighting the importance of preparedness in the event of an emergency related to the structure. With a maximum discharge capacity of 296 cubic feet per second, the dam's risk management measures and overall safety protocols are crucial for ensuring the protection of downstream communities and the surrounding environment.

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.
