Summary
It is primarily used for tailings disposal and is classified as an earth dam with a height of 20 feet and a storage capacity of 193 acre-feet. The dam does not have a spillway and is not regulated by the state, although it undergoes regular inspections by the Mine Safety and Health Administration.
Despite being categorized as having a high risk potential, Sedimentation Pond No 11 Stage 2 is currently not rated in terms of its condition assessment. The dam has a normal storage capacity of 29 acre-feet and covers a surface area of 7 acres. With no associated structures and one outlet gate, the dam was last inspected in February 2011. The risk management measures and emergency action plan status for the dam are not available at this time, indicating a need for further assessment and preparedness.
In the realm of water resource and climate enthusiasts, Sedimentation Pond No 11 Stage 2 stands out as a crucial component of tailings management in the area. Its location and design make it a significant structure in the region, although its risk potential and lack of recent assessments highlight the need for continued monitoring and evaluation to ensure the safety and efficiency of its operation. As efforts to address climate change and water resource management intensify, understanding and improving the infrastructure of dams like Sedimentation Pond No 11 Stage 2 will be essential for sustainable development and environmental protection.

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.
