Nantahala - Gated Spillway And 2 Fuseplugs dam
Nantahala - Gated Spillway And 2 Fuseplugs
Located in Macon, North Carolina, the Nantahala - Gated Spillway and 2 Fuseplugs structure is a key component of the Nantahala River hydroelectric system. Built in 1942, this gravity dam stands at a height of 45 feet and has a storage capacity of 126,000 acre-feet. With a spillway width of 159 feet, it is designed for controlled water release to manage high discharge levels.
Owned by a public utility, this dam is inspected by the Federal Energy Regulatory Commission to ensure its safe operation. The hazard potential is rated as high, with a very high risk assessment score. Although the condition assessment is not available, emergency action plans are in place to address any potential risks or emergencies. The structure plays a crucial role in providing hydroelectric power to the region.
Situated in a picturesque location, the Nantahala - Gated Spillway and 2 Fuseplugs structure not only serves as a vital infrastructure for water resource management but also contributes to the beauty of the surrounding landscape. With a rich history dating back to its completion in 1942, this gravity dam continues to play a significant role in providing renewable energy while ensuring the safety of the local community and the environment.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Nantahala - Gated Spillway And 2 Fuseplugs
Where does the data for Nantahala - Gated Spillway And 2 Fuseplugs 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.
