Summary
Standing at a height of 657 feet and with a length of 4800 feet, this impoundment has a storage capacity of 6222 acre-feet. The Mine Safety and Health Administration oversees the regulatory and inspection aspects of this high-hazard potential structure.
Despite not being state-regulated or permitted, Killarney Slurry Impoundment poses a significant risk due to its high-hazard potential. While the condition assessment is not available, the emergency action plan (EAP) status and risk management measures are currently not specified. With no inundation maps prepared or risk assessments conducted, there is a critical need for enhanced safety protocols and monitoring of this impoundment to mitigate potential hazards.
For water resource and climate enthusiasts, Killarney Slurry Impoundment serves as a noteworthy structure in Raleigh County, West Virginia. The impoundment's significant size and potential risks underscore the importance of robust regulatory oversight and emergency preparedness measures. As discussions around dam safety and environmental protection continue to evolve, the management and monitoring of impoundments like Killarney Slurry are integral to safeguarding water resources and ecosystems in the region.

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.
