Devils Lake Dam dam
Devils Lake Dam
Devils Lake Dam, also known as Seven Devils Dam, is a private-owned structure located in Watauga, North Carolina. Built in 1965, this dam serves a primary purpose of recreation along the Watauga River-Tr. With a hydraulic height of 34 feet and a structural height of 46 feet, the dam spans 410 feet in length and has a storage capacity of 74 acre-feet. Despite being categorized as an Earth dam, Devils Lake Dam boasts a high hazard potential but has been rated as satisfactory in its condition assessment as of March 2021.
Managed by the North Carolina Department of Environmental Quality's Dam Safety Program, Devils Lake Dam is subject to regular state regulation, permitting, inspection, and enforcement to ensure its safety and compliance with guidelines. The dam's emergency action plan was last revised in August 2018, with a two-year inspection frequency in place to monitor its ongoing condition. The dam's location in Foscoe, with a spillway type and width unspecified, presents both recreational opportunities and potential risks, highlighting the importance of proper management and maintenance to mitigate any hazards.
As a focal point for water resource and climate enthusiasts, Devils Lake Dam stands as a testament to the balance between human recreation and environmental responsibility. With its strategic position within the Watauga River-Tr watershed and close proximity to Nashville District, the dam serves as a vital component of the region's hydrological infrastructure. By upholding its state-regulated status and satisfactory condition, Devils Lake Dam continues to provide a safe and enjoyable recreational experience while safeguarding against potential risks and ensuring the preservation of its surrounding 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 Devils Lake Dam
Where does the data for Devils 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 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.
