Sugar Mtn Dam dam
Sugar Mtn Dam
Sugar Mtn Dam, also known as Snow Lake, is a private-owned structure located in Avery County, North Carolina, near the city of Banner Elk. This earth-type dam stands at a hydraulic height of 27.2 feet and a structural height of 31.7 feet, with a total length of 370 feet. The dam's primary purpose is listed as "Other," with a storage capacity of 11 acre-feet and a normal storage level of 8 acre-feet. It is situated on Flattop Creek and is regulated, permitted, inspected, and enforced by the North Carolina Department of Environmental Quality's Dam Safety Program.
The dam's hazard potential is classified as "High," but its condition assessment as of June 2019 was deemed "Satisfactory." The last inspection date was recorded on June 25, 2019, with an inspection frequency of every two years. Despite its private ownership, the dam is subject to state regulation and enforcement to ensure its safety and compliance with standards. With its critical role in water resource management and climate resilience in the region, Sugar Mtn Dam serves as a vital structure in the local watershed, highlighting the importance of monitoring and maintaining infrastructure for sustainable water management in the face of changing environmental conditions.

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 Sugar Mtn Dam
Where does the data for Sugar Mtn 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.
