Summary
Built in 1950 for recreational purposes, this earth dam stands at a height of 30.3 feet and has a storage capacity of 56.7 acre-feet. With a surface area of 4.6 acres and a drainage area of 0.18 square miles, the dam serves as a vital water resource in the region.
Despite its low hazard potential and fair condition, Tennessee Gas Station 204 Lake Dam undergoes regular inspections every five years to ensure its safety and integrity. The last assessment in 2016 deemed the dam to be in satisfactory condition. Furthermore, emergency action plans are in place, although their last revision was in 2017. With a maximum discharge of 156 cubic feet per second, this dam plays a crucial role in managing water flow and providing recreational opportunities in the area.
In the picturesque setting of Vales Mills, Tennessee Gas Station 204 Lake Dam stands as a testament to human engineering and its harmonious relationship with nature. As climate change continues to affect water resources, the preservation and maintenance of such structures are paramount in ensuring the sustainable management of our valuable water sources.

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.
