Summary
Completed in 2011, this earth dam stands at a hydraulic height of 34.2 feet and has a structural height of 38.2 feet. It holds a maximum storage capacity of 93 acre-feet and covers a surface area of 5 acres, serving the surrounding community as a popular recreational spot along TribLaurel Branch.
Managed by the Tennessee Safe Dams Program, Mercer Logan is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite being classified as low hazard potential, the dam has a moderate risk assessment rating, indicating the need for continued monitoring and risk management measures. With a satisfactory condition assessment as of January 2021, Mercer Logan offers a safe and enjoyable environment for water resource and climate enthusiasts to appreciate and enjoy the beauty of its surroundings.
As a significant structure within the water resource management system, Mercer Logan plays a crucial role in providing recreational opportunities while also being subject to regular inspections and maintenance to ensure its continued safety and functionality. Situated in a picturesque location in Franklin, Tennessee, this dam serves as a testament to the intersection of human engineering with natural landscapes, making it a point of interest for those fascinated by the complexities of water resource management and the impacts of climate on infrastructure.

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.
