Dewar Lake Dam dam
Dewar Lake Dam
Dewar Lake Dam, located in Lillington, North Carolina, is a private-owned structure primarily used for irrigation purposes. Built in 1951, this earth dam stands at a structural height of 12 feet with a hydraulic height of 8 feet, stretching 480 feet in length. The dam has a storage capacity of 77 acre-feet, providing water for irrigation, recreation, and water supply in the area. Avents Creek serves as the river or stream source for the dam.
Despite being privately owned, Dewar Lake Dam is subject to state inspection, ensuring its structural integrity and safety. The dam has not been rated for its condition assessment, indicating the need for further evaluation. With a significant hazard potential, the dam is closely monitored for any risks or safety concerns. The last inspection of Dewar Lake Dam took place in March 2001, highlighting the importance of regular maintenance and assessment to prevent any potential hazards.
As a crucial water resource in Harnett County, Dewar Lake Dam plays a vital role in providing water for irrigation and other essential purposes. The dam's location in a high-risk area emphasizes the need for effective risk management measures and emergency preparedness. Despite not being federally regulated, Dewar Lake Dam's significance in water supply and irrigation highlights the importance of maintaining its structural integrity and safety for the surrounding community and ecosystem.

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 Dewar Lake Dam
Where does the data for Dewar Lake Dam 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.
