Crown Mine Pond Dam dam
Crown Mine Pond Dam
Located in Farmersville, Illinois, the Crown Mine Pond Dam stands as a significant structure that serves not only for recreational purposes but also for water supply. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Crown Mine Pond Dam
Where does the data for Crown Mine Pond Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
