Harnett Co Raw Water Reservoir dam
Harnett Co Raw Water Reservoir
Located in Lillington, North Carolina, the Harnett CO Raw Water Reservoir is a vital water supply system owned by the local government. 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.
- 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 Harnett Co Raw Water Reservoir
Where does the data for Harnett Co Raw Water Reservoir 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 High 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.
