Summary
Built in 1959 by the USDA NRCS, this Earth-type dam stands at a height of 24 feet and has a hydraulic height of 16 feet. Its primary purpose is flood risk reduction along Thompson Creek, with a storage capacity of 277 acre-feet and a surface area of 14.7 acres.
The dam is regulated by the Tennessee Safe Dams Program, ensuring that it undergoes regular inspections and maintenance to meet safety standards. Despite its low hazard potential and satisfactory condition assessment in 2019, the risk assessment is moderate (3), highlighting the importance of ongoing risk management measures to mitigate potential threats. With no outlet gates and an uncontrolled spillway type, Thompson Creek #8 serves as a crucial infrastructure for flood control in the region, contributing to the overall water resource and climate resilience efforts.
As water resource and climate enthusiasts, understanding the role of dams like Thompson Creek #8 in managing flood risks and protecting communities is essential. By recognizing the regulatory oversight, design features, and risk assessment of such structures, we can appreciate the integral role they play in safeguarding water resources and enhancing climate resilience. Thompson Creek #8 stands as a testament to the collaborative efforts of private owners, regulatory agencies, and designers in ensuring the safety and effectiveness of flood control infrastructure in Tennessee.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
