Harris Lagoon dam
Harris Lagoon
Harris Lagoon in Nash, North Carolina, is a privately owned earth dam with a significant hazard potential and a hydraulic height of 15.5 feet. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Harris Lagoon
Where does the data for Harris Lagoon come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
