Summary
Built in 1950, it stands at a structural height of 15 feet and has a hydraulic height of 11 feet, with a length of 250 feet. The dam has a maximum storage capacity of 78 acre-feet, with a normal storage capacity of 60 acre-feet, serving a drainage area of 0.4 square miles.
Despite being classified as a low hazard potential structure, Sinclair has a moderate risk assessment rating. The dam is currently not rated for its condition, with the last inspection taking place in September 2020. Although there are no associated structures or locks, the dam has uncontrolled spillways and no outlet gates. The risk management measures and emergency action plan for Sinclair are currently not specified, highlighting the need for continued monitoring and assessment of this critical water resource infrastructure.
Located within the Nashville District, Sinclair is under the jurisdiction of the state of Tennessee but is not regulated or permitted by state agencies. With its unique design and historical significance, Sinclair serves as a vital component of the local water management system. As climate change impacts continue to affect water resources, the maintenance and assessment of dams like Sinclair become increasingly important in ensuring the safety and sustainability of our communities.

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.
