Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E) dam
Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E)
The Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E) is a significant structure located in Sumner, Tennessee, owned and operated by the Tennessee Valley Authority (TVA). This Earth-type dam, completed in 1970, stands at a height of 24 feet and has a length of 9809 feet, with a storage capacity of 3800 acre-feet. The dam's primary purpose is for ash disposal, serving as a containment area for fly ash generated by the plant's operations.
The dam's hazard potential is classified as significant, with a moderate risk assessment. The structure's last inspection was conducted in December 2020, with no available condition assessment at the time. The dam's spillway type is uncontrolled, with an associated spillway width of 9 feet. While the dam is not state-regulated, TVA oversees its design, construction, inspection, and operation. Despite its age, the Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E) continues to play a crucial role in managing ash disposal and ensuring environmental protection in the area.
Overall, the Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E) serves as a vital infrastructure for the containment and management of fly ash in Sumner, Tennessee. As a federal-owned structure, it reflects TVA's commitment to environmental stewardship and responsible management of water resources. With its unique design and operational characteristics, the dam stands as a testament to the importance of maintaining and monitoring critical infrastructure to ensure the safety and sustainability of water resources in the region.

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 Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E)
Where does the data for Gallatin Fossil Plant - Ash Disposal Area Perimeter Dike (Pond E) 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 Significant 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.
