Waynesville Water Supply Dam dam
Waynesville Water Supply Dam
The Waynesville Water Supply Dam in North Carolina, completed in 1982, serves a dual purpose of flood risk reduction and water supply for the local government of Hazelwood. Situated along Allen Creek, this earth dam stands at a structural height of 142 feet, with a hydraulic height of 100 feet and a length of 870 feet. The dam has a maximum storage capacity of 3,660 acre-feet and covers a surface area of 76.4 acres, benefiting from a drainage area of 8,256 acres.
Despite its satisfactory condition assessment as of March 2017, the dam poses a high hazard potential, necessitating regular inspections every two years. The North Carolina Dam Safety Program oversees the state-regulated facility, ensuring compliance with safety regulations and enforcement measures. With a maximum discharge capacity of 18,878 cubic feet per second, the Waynesville Water Supply Dam plays a crucial role in mitigating flood risks and securing a vital water supply for the community.
For water resource and climate enthusiasts, the Waynesville Water Supply Dam presents an intriguing case study in sustainable water management and infrastructure resilience. As a key asset in flood risk reduction and water supply operations, the dam underscores the importance of proactive maintenance and regulatory oversight in safeguarding communities against natural disasters and ensuring reliable access to essential resources. Its strategic location, design features, and operational capacity make it a notable example of effective water resource management in the face of changing climate patterns and environmental challenges.
Dam data reference
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 Waynesville Water Supply Dam
Where does the data for Waynesville 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 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.
