Summary
This earth dam, with a hydraulic height of 11.9 feet and a structural height of 15.9 feet, serves primarily for recreational purposes. Situated on the Yadkin River-Tr, this dam has a high hazard potential but is currently assessed to be in fair condition as of November 2020.
Managed by the North Carolina Department of Environmental Quality's Dam Safety Program, Willowbrook Carp Lake Dam is subject to state regulation, permitting, inspection, and enforcement. With a normal storage capacity of 9.5 acre-feet and a maximum storage of 12.7 acre-feet, this dam covers a surface area of 2 acres. While the exact year of completion is unknown, the dam undergoes inspections every two years to ensure its safety and compliance with regulations.
For water resource and climate enthusiasts, Willowbrook Carp Lake Dam presents an interesting case study on the balance between recreational use and the potential risks associated with high hazard dams. As the dam is closely monitored by state regulatory agencies, including the North Carolina Department of Environmental Quality, it serves as a reminder of the importance of effective dam management to ensure public safety and environmental protection in water resource management.

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.
