Old Tom Creek Ws Str 29 dam
Old Tom Creek Ws Str 29
Old Tom Creek WS Str 29 is a crucial flood risk reduction structure located in Henderson, Illinois. Built in 1956 by USDA NRCS, this earth dam stands at a height of 22 feet and has a length of 391 feet, providing a maximum storage capacity of 107 acre-feet. Situated on the TR- OLD TOM CREEK N stream, this structure is regulated by the IDNR and inspected by the Natural Resources Conservation Service, with a significant hazard potential and a moderate risk assessment.
Despite its age, Old Tom Creek WS Str 29 remains a vital component of the area's flood risk management system, with a drainage area of 0.62 square miles and a maximum discharge capacity of 472 cubic feet per second. The dam's uncontrolled spillway and outlet gates are designed to handle potential flooding events, ensuring the safety of nearby communities such as Biggsville. With its primary purpose being flood risk reduction, this structure plays a crucial role in protecting the region from potential water-related disasters.
As a structure owned and maintained by the local government, Old Tom Creek WS Str 29 represents a collaborative effort between various agencies and organizations to safeguard water resources and mitigate the impacts of climate change in the region. Its continued operation and maintenance are essential for ensuring the safety and resilience of the community in the face of evolving environmental challenges.

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 Old Tom Creek Ws Str 29
Where does the data for Old Tom Creek Ws Str 29 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.
