The dam, primarily used for recreation purposes, is an earth dam with a hydraulic height of 18 feet and a structural height of 23 feet. It has a NID storage capacity of 58 acre-feet, with a maximum storage and normal storage of 58 and 36 acre-feet respectively.

Despite being classified as having a low hazard potential, the dam is in fair condition as of the last inspection in May 2012. The dam, with a length of 475 feet and a surface area of 5 acres, is situated along Horse Creek-Tr and is not regulated by the state. With no associated structures and no state permitting requirements, Lake Pinehurst Pond Dam #3 provides a picturesque recreational spot for water resource and climate enthusiasts to enjoy in the heart of North Carolina.

Overall, Lake Pinehurst Pond Dam #3 stands as a vital infrastructure for recreational purposes in the region, offering a serene environment for visitors to appreciate the beauty of the surrounding landscape. With its modest size and low hazard potential, the dam serves as a testament to the importance of maintaining and monitoring such structures to ensure the safety and enjoyment of all who visit.

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.
