Lenoir Water Supply Dam Dam
Lenoir Water Supply Dam
The Lenoir Water Supply Dam, located in Lenoir, North Carolina, is a vital infrastructure owned by the local government for water supply purposes. This concrete gravity dam on Zacks Fork Creek-Tr was completed in 1924 and has a structural height of 27 feet. With a drainage area of 530 square miles and a normal storage capacity of 27 acre-feet, the dam plays a crucial role in providing water to the surrounding area.
Despite its age, the Lenoir Water Supply Dam is in good condition and has a high hazard potential. Inspected in 2007, the dam has not been rated for its current condition. Although not regulated by the state, the dam is under periodic inspection to ensure its safety and reliability. With its proximity to Congress District 05 in North Carolina and a maximum discharge of 333 cubic feet per second, the dam remains a key component of the local water supply infrastructure.
Water resource and climate enthusiasts will find the Lenoir Water Supply Dam an intriguing structure that highlights the importance of proper water management in communities. Its historical significance, combined with its essential role in providing water to the area, makes it a noteworthy site for those interested in the intersection of water resources, infrastructure, and environmental stewardship.

About Lenoir Water Supply Dam
Where does the data for Lenoir Water Supply 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 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 below 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.

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.
