Summary
Standing at a height of 20 feet, the dam has a storage capacity of 240 acre-feet and covers a surface area of 30 acres. The dam's spillway type is uncontrolled, and it does not have any associated locks or outlet gates.
The dam is regulated by the Mississippi Department of Environmental Quality and is subject to state inspections and enforcement. While its hazard potential is currently undetermined, its condition is rated as "not rated", suggesting that further assessments may be needed. The risk assessment for the dam is moderate (3), indicating a need for ongoing monitoring and potentially, risk management measures to ensure the safety and integrity of the structure.
Overall, Mayfield Lake Dam serves as a recreational resource in the area, but its condition and risk profile warrant continued attention and evaluation to mitigate any potential hazards and ensure the safety of the surrounding community and environment. As a key infrastructure in the region, it remains essential to maintain and manage the dam effectively to withstand the impacts of climate change and changing water resource dynamics.

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.
