Summary
Completed in 1952, this earth dam serves a primary purpose of recreation and is regulated by the Tennessee Safe Dams Program. Situated on the Tribelk River, Logan has a structural height of 52 feet and a hydraulic height of 43.5 feet, with a maximum storage capacity of 1043 acre-feet and a normal storage capacity of 690 acre-feet. The dam covers a surface area of 36 acres and has a drainage area of 0.47 square miles.
Despite being classified as having a low hazard potential, Logan has a moderate risk assessment rating of 3. The dam has been assessed to be in satisfactory condition as of its last inspection in January 2019, with an inspection frequency of every 3 years. The spillway type for Logan is uncontrolled, and there are no outlet gates associated with the structure. While the dam does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, it is crucial for water resource and climate enthusiasts to monitor Logan's risk management measures and any potential updates to its safety protocols to ensure the continued protection of the surrounding community and environment.

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.
