Summary
Managed by the Tennessee Safe Dams Program, this Earth-type dam was completed in 1945 and stands at a structural height of 25.5 feet, with a hydraulic height of 20.9 feet. With a storage capacity of 35 acre-feet and a surface area of 2.8 acres, the lake provides a serene environment for outdoor activities like fishing, boating, and picnicking.
Despite its low hazard potential and satisfactory condition assessment, Fernvale Lake is subject to state regulation, inspection, and enforcement to ensure its safety and integrity. Located near the TRIBSOUTH HARPETH RIVER and under the jurisdiction of the Nashville District, the dam is equipped with an uncontrolled spillway and has no associated locks or outlet gates. With a drainage area of 0.44 square miles, the lake contributes to the local ecosystem and serves as a haven for wildlife, making it a valuable asset in the region's water management infrastructure.
Fernvale Lake's risk assessment is moderate, indicating the need for ongoing monitoring and risk management measures. The dam's Emergency Action Plan (EAP) status and inundation maps preparation are currently unspecified, highlighting areas for potential improvement in emergency preparedness. As a beloved recreational spot in the city of FERNVALE, this picturesque lake plays a crucial role in water resource management, environmental conservation, and community engagement, making it a vital resource for residents and visitors alike.

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.
