Southern Il Power Fly Ash Disp Pond B-3 Dam dam
Southern Il Power Fly Ash Disp Pond B-3 Dam
Located in Williamson County, Illinois, the Southern Il Power Fly Ash Disp Pond B-3 Dam, also known as Fly Ash Disposal Pond B-3, is a critical structure designed by BECHTEL to serve as a debris control system. Completed in 1986, this earth dam stands at a height of 36 feet and stretches 700 feet in length, with a storage capacity of 140 acre-feet. The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
The dam, situated near the TRIB LITTLE SALINE CREEK in the city of HUGDENS, plays a significant role in managing debris and controlling water flow in the area. With a low hazard potential and a moderate risk assessment rating, the Southern Il Power Fly Ash Disp Pond B-3 Dam is considered to be in good condition, although detailed condition assessment data is not currently available. Despite its uncontrolled spillway and outlet gates, the dam continues to effectively fulfill its primary purpose of debris control, providing a vital resource for water management in the region.
Water resource and climate enthusiasts will find the Southern Il Power Fly Ash Disp Pond B-3 Dam to be an intriguing example of engineering ingenuity in managing water flow and debris in the region. With its historical significance and ongoing regulatory oversight, this dam serves as a testament to the importance of infrastructure in protecting communities and the environment from potential hazards. As efforts continue to ensure the safety and functionality of the dam, it remains a key component of the water management system in Williamson County, Illinois.

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 Southern Il Power Fly Ash Disp Pond B-3 Dam
Where does the data for Southern Il Power Fly Ash Disp Pond B-3 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.
