Watauga Dam dam
Watauga Dam
Watauga Dam, located on the Watauga River in Carter, Tennessee, is a rockfill dam completed in 1948 by the Tennessee Valley Authority (TVA). With a height of 332 feet and a storage capacity of 751,557 acre-feet, the dam serves multiple purposes including flood risk reduction, hydroelectric power generation, recreation, and water supply for the region. The dam's reservoir, Watauga Lake, covers an area of 6,440 acres and is a popular destination for outdoor enthusiasts.
The dam's spillway, with a width of 385 feet, is uncontrolled, and the outlet gates include slide gates, uncontrolled releases, and valves. Despite being categorized as having a high hazard potential, the dam's risk assessment is moderate. The TVA is responsible for the dam's ownership, funding, design, construction, regulation, inspection, and operation, ensuring its safety and functionality. While the dam has not undergone recent condition assessments, emergency action plans are in place to address any potential hazards or incidents.
Overall, Watauga Dam stands as a vital infrastructure asset in Tennessee, providing essential services such as flood protection, water storage, and renewable energy generation. Its strategic location on the Watauga River highlights its importance in managing water resources and addressing climate-related challenges in the region. Enthusiasts of water resources and climate resilience will find Watauga Dam to be a fascinating example of sustainable infrastructure development and management in the face of changing environmental conditions.

About Watauga Dam
Where does the data for Watauga 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.
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.
