Summary
Mather Coal Co. Silt Dam, located in Martin, Floyd County, Kentucky, serves as an essential structure for debris control along the Beaver Creek Osborn Branch. Built in 1972 by the USDA NRCS, this private-owned earth dam stands at a height of 34 feet and spans 250 feet in length. With a maximum storage capacity of 50 acre-feet, the dam plays a crucial role in managing the flow of water and protecting the surrounding area from potential hazards.
Despite its high hazard potential, the P.W. Mather Coal Co. Silt Dam is currently in a condition assessment status of "Not Available," highlighting the importance of regular inspections and maintenance. The dam features an uncontrolled spillway and outlet gates, with a moderate risk assessment rating of 3. While there is no Emergency Action Plan (EAP) in place at the moment, it is imperative for the stakeholders to ensure that proper risk management measures are implemented to mitigate any potential threats and safeguard the community and environment.
Water resource and climate enthusiasts would find the P.W. Mather Coal Co. Silt Dam an intriguing structure, given its significance in debris control and water management in the region. With its rock and soil foundation, the dam stands as a testament to the collaborative efforts of the USDA NRCS in safeguarding the local water resources. Moving forward, continued monitoring and risk assessment measures will be essential to ensure the long-term integrity and functionality of this vital infrastructure.

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.
