Summary
Built in 1951 by CROWN COAL CO., this private-owned Earth dam spans 2036 feet in length and stands at a height of 11 feet, with a storage capacity of 97 acre-feet. Situated on TRIB MACOUPIN CREEK, this dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections, indicating a commitment to safety and compliance with state regulations.
With a hazard potential deemed significant and a high risk assessment rating, Crown Mine Pond Dam is a structure that demands attention and careful monitoring. While the condition assessment is currently marked as "Not Available," the dam's emergency action plan status, risk management measures, and inundation maps readiness are also not specified. Despite these uncertainties, the dam serves as a critical asset in the region, highlighting the intersection of water resource management and climate resilience in safeguarding communities against potential risks associated with dam failure.
As enthusiasts of water resources and climate issues, the Crown Mine Pond Dam presents an intriguing case study in the realm of dam safety and infrastructure management. The dam's historical significance, coupled with its vital role in water supply and recreation, underscores the importance of proactive risk assessment, emergency preparedness, and continual monitoring to ensure the safety and resilience of such essential structures in the face of evolving environmental challenges and climate dynamics.

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.
