Summary
The dam is classified as an Earth type with a structural height of 11 feet and a length of 305 feet. It has a storage capacity of 146 acre-feet and a normal storage level of 65 acre-feet, covering a surface area of 27 acres.
Despite being privately owned and not regulated by the state, the dam's condition assessment is currently listed as "Not Rated" with an undetermined hazard potential. The last inspection took place in February 2013, with an inspection frequency of 5 years. While the Emergency Action Plan (EAP) status and risk assessment information are not available, there have been no modifications or enhancements to the dam structure since its completion.
With its proximity to the Great Pee Dee River and the recreational opportunities it offers, Willoughby Farms Pond Dam presents an intriguing case study for water resource and climate enthusiasts. The dam's historical significance, design characteristics, and current condition raise important questions about the management and maintenance of private dams in the region, as well as their role in water resource management and environmental conservation efforts.

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.
