Summary
It has a structural height of 16.4 feet and a storage capacity of 64 acre-feet. The dam, completed in an unspecified year, spans 850 feet in length and covers an impressive surface area of 4 acres. Although it is not regulated by the state, it is inspected periodically to ensure its safety and integrity.
Located within the Wilmington District of the US Army Corps of Engineers, Harris Lagoon serves a primary purpose that is classified as 'Other'. The dam's design and construction details remain unspecified, but its association with federal agencies and funding is notably absent. Despite not being state-regulated, the dam's significant hazard potential underscores the importance of ongoing inspections and risk management measures to safeguard surrounding communities and water resources. With the last inspection conducted in 2004, the condition of Harris Lagoon remains unrated, highlighting the need for continued monitoring and evaluation to mitigate potential risks.
For water resource and climate enthusiasts, Harris Lagoon offers a fascinating case study of a privately owned dam with a unique set of characteristics and challenges. Its location in Nash, North Carolina, and its proximity to the Wilmington District make it a noteworthy feature within the local landscape. As efforts to address climate change and enhance water resource management continue to evolve, the importance of maintaining the safety and integrity of structures like Harris Lagoon becomes increasingly vital. By staying informed about its condition, hazard potential, and risk management strategies, stakeholders can work together to ensure the long-term sustainability and resilience of this essential water resource infrastructure.

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.
