Summary

This reservoir, completed in 1997, serves as a key source of water from the Cape Fear River, providing 5.6 million gallons of storage capacity. With a primary purpose of water supply, this earth dam structure stands at 28 feet tall and is regulated by the North Carolina Dam Safety Program.

The Harnett CO Raw Water Reservoir has a high hazard potential and is assessed to be in fair condition as of the last inspection in October 2020. Despite this, the reservoir meets state regulations for permitting, inspection, and enforcement. The emergency action plan (EAP) for the dam has been regularly updated, ensuring that necessary measures are in place to mitigate risks and protect surrounding communities in case of emergencies.

Enthusiasts of water resources and climate will appreciate the critical role that the Harnett CO Raw Water Reservoir plays in providing essential water supply to the region. This reservoir not only supports the local community but also aligns with state regulations and safety standards, highlighting the importance of sustainable water management practices in ensuring a reliable and secure water source for the future.

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.
