About this dam

Chatuge Dam

Chatuge Dam, also known as Chatuge Lake, is a federal-owned structure located in Hayesville, North Carolina, along the Hiwassee River. Built in 1942 by the Tennessee Valley Authority (TVA), the dam stands at a height of 144 feet and has a hydraulic height of 132 feet, serving primarily for flood risk reduction. With a normal storage capacity of 226,600 acre-feet and a maximum storage of 285,552 acre-feet, the dam covers a surface area of 6,700 acres and has a drainage area of 189 square miles.

The dam boasts a controlled spillway with a width of 325 feet and features vertical lift outlet gates for water release. Despite a high hazard potential, the condition assessment of Chatuge Dam is not available, indicating a need for further inspection. The dam area offers recreational opportunities and serves as a water supply source, in addition to its flood risk reduction and hydroelectric functions. Managed by the TVA, Chatuge Dam stands as a vital structure in water resource management and climate resilience efforts in the region.

Overall, Chatuge Dam plays a crucial role in the Tennessee Valley Authority's operations, with a focus on flood risk reduction, hydroelectric power generation, recreation, and water supply. Its strategic location and design make it a key contributor to water resource management in the area. Despite its high hazard potential, the dam continues to be monitored and inspected regularly to ensure public safety and the efficient functioning of its multiple purposes. As a significant landmark along the Hiwassee River, Chatuge Dam stands as a testament to the importance of sustainable water resource management and climate adaptation strategies 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.

FAQ

About Chatuge Dam

Where does the data for Chatuge 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.
