Summary

Managed by the Tennessee Safe Dams Program, this local government-owned lake serves various purposes, including water resource management and flood control. With a maximum storage capacity of 2549 acre-feet and a normal storage level of 1100 acre-feet, Tracy City Lake covers an area of 100 acres and has a drainage area of 2.26 square miles.

The earth dam at Tracy City Lake stands at a hydraulic height of 42 feet and a structural height of 52 feet, ensuring the safety and stability of the reservoir. Despite its high hazard potential, the dam's condition assessment in December 2020 reported it as satisfactory, with a moderate risk level. The reservoir is equipped with an uncontrolled spillway and has no outlet gates or associated structures. Tracy City Lake provides a picturesque setting for water resource and climate enthusiasts, offering opportunities for outdoor recreation and appreciation of its ecological significance within the Nashville District.

As a vital water resource in Tennessee, Tracy City Lake plays a crucial role in maintaining the region's water supply and supporting the local ecosystem. With its regulated state jurisdiction and regular inspections, the dam ensures the safety of surrounding communities and minimizes potential risks. Whether you're an avid angler, nature lover, or climate enthusiast, Tracy City Lake offers a serene escape and a glimpse into the intersection of water management and environmental conservation in the heart of Grundy County.

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. 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

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, 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.
