Summary
Managed by the Mine Safety and Health Administration, this impoundment has a high hazard potential and currently lacks condition assessment data. Despite being non-regulated by the state, it is crucial for water resource and climate enthusiasts to monitor this structure due to its potential environmental impact.
The dam, completed at an unknown date, poses a significant risk to the surrounding area in the event of a failure, as indicated by its high hazard potential status. With no available information on its condition assessment or emergency action plan, it is essential for stakeholders to advocate for regular inspections and risk management measures to ensure the safety and integrity of the 5-C Impoundment. Additionally, further research and data collection are needed to fully understand the potential consequences of any structural issues or incidents.
Given its location in Washington County and association with tailings storage, the 5-C Impoundment is a critical piece of infrastructure that warrants attention from water resource and climate enthusiasts. By staying informed and advocating for proper maintenance and monitoring of this private dam, stakeholders can work towards mitigating potential risks and safeguarding the surrounding environment from any adverse impacts.

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.
