Summary
Owned by the local government and regulated by the Kentucky Division of Water, this earth dam was completed in 1977 with a primary purpose of flood risk reduction. With a dam height of 25 feet and a storage capacity of 186.9 acre-feet, it serves to protect the surrounding areas from potential flooding events.
The dam's condition assessment in 2018 rated it as fair with a low hazard potential, indicating its stability and effectiveness in managing floodwaters. The structure has a spillway width of 30 feet and covers a drainage area of 0.48 square miles. Despite being uncontrolled, the dam has been inspected regularly every 5 years to ensure its continued functionality. Situated along the West Fork Mayfield Creek, this dam plays a crucial role in mitigating flood risks and protecting the local community in Kirbyton.
Overall, West Fork Mayfield Creek FRS 45 stands as a testament to effective flood risk reduction measures in Kentucky. With its moderate risk assessment and continuous inspections, this structure remains a vital component in safeguarding the surrounding areas from potential inundation. As water resource and climate enthusiasts, it is important to recognize the importance of such infrastructure in managing and adapting to the changing dynamics of our natural 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.
