Summary
Built in 1963 by the USDA NRCS, this earth dam stands at a height of 26 feet and spans 300 feet in length, with a storage capacity of 65 acre-feet. The dam serves the primary purpose of flood risk reduction along the Tr- Biggerstaff Creek, providing protection to the surrounding area from potential inundation.
Managed and maintained by the Natural Resources Conservation Service, Mud River FRS 42 has a low hazard potential and a moderate risk assessment score of 3. The uncontrolled spillway has a width of 20 feet, and the dam features rock and soil foundations. While the condition assessment is currently unavailable, the structure has not been modified in recent years and lacks an emergency action plan. With a maximum discharge of 864 cubic feet per second, this dam plays a crucial role in managing water flow and mitigating flood risks in the region.
Overall, Mud River FRS 42 stands as a critical infrastructure asset for flood risk reduction in Butler, Kentucky. As water resource and climate enthusiasts, understanding the design, purpose, and operational details of this structure provides valuable insight into the efforts made to safeguard communities from potential flooding events. With its history dating back to the 1960s, this earth dam continues to play a significant role in water management and protection against flooding along the Tr- Biggerstaff Creek.

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.
