Deushane Slurry Impoundment 1 Dam dam
Deushane Slurry Impoundment 1 Dam
The Deushane Slurry Impoundment 1 Dam, also known as External Plugs Ep-1, is a privately owned structure located in Knox County, Illinois. Built in 1983 by the Midland Coal Company, this earth dam stands at a height of 28 feet and spans a length of 800 feet. Its primary purpose is for tailings storage and it serves as a fish and wildlife pond as well. The dam is regulated by the Illinois Department of Natural Resources and is subject to regular inspections and enforcement measures.
Situated near TRIB LITTLERS CREEK in London Mills, the Deushane Slurry Impoundment 1 Dam has a low hazard potential and a moderate risk assessment rating. Although its storage capacity is 65 acre-feet, the dam's normal storage level is reported as zero. The spillway, which is uncontrolled, has a width of 20 feet. Despite its lack of availability of condition assessment data, the dam has a designated inspection frequency of every five years.
Overall, the Deushane Slurry Impoundment 1 Dam is a significant structure in the region, serving multiple purposes while being subject to state regulations and inspections. With its unique design and history of construction, this dam plays a vital role in managing tailings and providing habitat for fish and wildlife. Climate and water resource enthusiasts will find the details of this dam's characteristics and operational status intriguing.

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 Deushane Slurry Impoundment 1 Dam
Where does the data for Deushane Slurry Impoundment 1 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 Low 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.
