Summary
This earth dam stands at a hydraulic height of 10.5 feet and a structural height of 16 feet, with a length of 300 feet. It has a normal storage capacity of 67.2 acre-feet and a maximum storage of 41 acre-feet, covering a surface area of 6.4 acres. Despite not being regulated by the state, the dam has been inspected as of September 2016 and has a high hazard potential.
The dam, situated on Jumping Creek-Tr, provides not only recreational opportunities but also poses a potential risk due to its high hazard potential. Although its condition is currently not rated, regular inspections are crucial to ensure the safety of the surrounding area and downstream communities. With its close proximity to Spring Lake, any potential issues with the dam could have significant impacts on the local environment and water resources.
Water resource and climate enthusiasts should take note of Harnett Metals Dam as part of the larger network of structures contributing to water management in the area. Understanding its design, purpose, and current condition can provide valuable insights into the resilience of water infrastructure and the importance of regular maintenance and monitoring in the face of changing climate conditions.

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.
