Summary

Completed in 1979, this earth dam stands at a height of 18 feet and spans a length of 680 feet, with a reservoir capacity of 197 acre-feet and a surface area of 10.2 acres. The primary purpose of Mud River FRS 44 is flood risk reduction, serving as a vital infrastructure to protect the surrounding area from potential flooding events.

Managed by the Kentucky Division of Water, Mud River FRS 44 is a state-regulated structure that undergoes regular inspections to ensure its operational integrity. Despite being categorized as having a low hazard potential, the dam's condition assessment in 2017 was rated as fair. With a moderate risk assessment score of 3, measures for risk management are yet to be explicitly detailed. Located along TR-Biggerstaff Creek, this dam plays a key role in safeguarding the local community and environment from the impacts of extreme weather events and changing climatic patterns.

For water resource and climate enthusiasts, Mud River FRS 44 presents an intriguing case study of a critical infrastructure designed for flood risk reduction in a rural setting. The dam's history, design specifications, and ongoing regulatory oversight by the state of Kentucky provide valuable insights into the management of water resources and the intersection of infrastructure development with environmental conservation efforts. As climate change continues to pose challenges to water management systems, understanding the role of structures like Mud River FRS 44 becomes increasingly important in ensuring the resilience of communities facing a changing climate landscape.

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.
