Summary
With a height of 40 feet and a length of 210 feet, the dam provides a storage capacity of 37 acre-feet and has a low hazard potential. It is situated on Tr- Boardtown Creek within the Nashville District of the US Army Corps of Engineers.
The dam's spillway is uncontrolled with a width of 40 feet, and it has a maximum discharge capacity of 820 cubic feet per second. While the dam's condition assessment is currently listed as "Not Available," the risk assessment is moderate (3), indicating a level of risk that requires attention. Despite being a private-owned structure, the USDA NRCS was responsible for the construction and design of Mayfield Dam, highlighting the collaboration between public and private entities in managing water resources for both wildlife preservation and recreational purposes in the region.
Overall, Mayfield Dam serves as a crucial component in the conservation efforts for fish and wildlife habitats in the area, while also offering recreational opportunities for visitors. The dam's importance lies not only in its structural function but also in its contribution to the overall environmental health of Tr- Boardtown Creek and the surrounding Gilmer County. As climate change continues to impact water resources, the maintenance and management of dams like Mayfield Dam will be essential in ensuring the sustainability and resilience of ecosystems in the face of changing 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.
