Summary

Completed in 1964, this flood risk reduction structure stands at a height of 32 feet and spans a length of 450 feet, with a storage capacity of 2050 acre-feet. The dam serves the primary purpose of flood risk reduction along the Mud River, with a normal storage capacity of 252 acre-feet and a drainage area of 8.7 square miles.

Managed by the Kentucky Division of Water, Mud River FRS No 5 has a low hazard potential and is currently assessed to be in fair condition as of March 2017. The dam undergoes inspection every five years to ensure its integrity and safety. Although no emergency action plan (EAP) is currently in place, the risk assessment for this structure is moderate. With a designated emergency contact and risk management measures in place, the Mud River FRS No 5 plays a crucial role in mitigating flood risks in the region.

With its controlled spillway and moderate risk assessment, Mud River FRS No 5 stands as a vital infrastructure for flood risk reduction along the Mud River. As climate change continues to impact water resources and weather patterns, structures like Mud River FRS No 5 become increasingly important for protecting communities and minimizing the potential impacts of flooding events. Moving forward, ongoing maintenance and monitoring of this dam will be essential to ensure its continued effectiveness in safeguarding the surrounding area from flood risks.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
