Summary
Built in 1958 by the USDA NRCS, this Earth-type dam stands at a hydraulic height of 23.1 feet and a structural height of 25.1 feet, with a length of 475 feet and a NID storage capacity of 113 acre-feet. With a normal storage capacity of 92 acre-feet and a surface area of 10 acres, Mayfield Lake plays a crucial role in water management in the region.
Managed by the Tennessee Safe Dams Program, Mayfield Lake has a low hazard potential and is classified as having a satisfactory condition assessment. The dam, which impounds Tribdoe Creek, is equipped with an uncontrolled spillway and has no outlet gates. Despite its moderate risk level, the dam's risk management measures and emergency action plan status are currently unclear. The last inspection in September 2019 showed no signs of immediate concern, but regular monitoring and maintenance are essential to ensure the continued safety and effectiveness of this important water resource in the region.
Overall, Mayfield Lake serves as a key water management structure in Tennessee, providing essential storage and flood control benefits. As a private dam regulated by the state, it represents a collaboration between government agencies and private entities to safeguard water resources and address potential risks. With its unique design and historical significance, Mayfield Lake stands as a testament to the importance of effective water resource management in the face of changing climate conditions.

Dam Data Reference
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.
