Summary

Owned by the local government and regulated by the KY Division of Water, this earth dam was completed in 1963 with a height of 26 feet and a length of 560 feet. The primary purpose of Mud River FRS 23 is flood risk reduction, serving to protect the surrounding area from potential inundation during periods of heavy rainfall or high water levels.

With a storage capacity of 108.5 acre-feet and a normal storage level of 16 feet, this structure on the Mud River covers a surface area of 3.1 acres and drains a watershed area of 0.71 square miles. Despite its low hazard potential and satisfactory condition assessment, Mud River FRS 23 is subject to regular inspections every five years to ensure its ongoing effectiveness in flood mitigation. The structure is designed with an uncontrolled spillway type and has not been modified since its completion, highlighting its stability and reliability in managing water flow in the region.

Managed and maintained by the Natural Resources Conservation Service, Mud River FRS 23 plays a crucial role in safeguarding the Russellville-area community from potential flood events. With its strategic location and design, this structure stands as a testament to effective water resource management and climate resilience efforts in the region. As water resource and climate enthusiasts, staying informed about the infrastructure and functionality of structures like Mud River FRS 23 is essential for understanding and addressing the challenges posed by changing environmental conditions.

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.
