Old Tom Creek Ws Str 24
Old Tom Creek WS Str 24 is a vital water structure located in Henderson, Illinois, designed by USDA NRCS to primarily reduce flood risks in the area. This earth dam, completed in 1955, stands at a height of 25 feet and spans 364 feet in length, providing a storage capacity of 57 acre-feet to manage the flow of the TR- HENDERSON S and TR- MISS rivers. With a low hazard potential and moderate risk assessment, this dam is state-regulated by IDNR and undergoes regular inspections by the Natural Resources Conservation Service.
Situated in Biggsville, Old Tom Creek WS Str 24 plays a crucial role in protecting the surrounding areas from potential flooding events. Despite its uncontrolled spillway and outlet gates, this structure has been deemed to meet regulatory guidelines and poses a low risk to its immediate vicinity. The presence of a drainage area of 0.17 square miles and a maximum discharge capacity of 238 cubic feet per second further highlight the importance of this dam in managing water resources and enhancing climate resilience in the region.
The construction, maintenance, and inspection of Old Tom Creek WS Str 24 are carried out by the Natural Resources Conservation Service, ensuring its operational efficiency and safety. With a history dating back to the mid-20th century, this earth dam continues to serve as a critical infrastructure for flood risk reduction in Henderson County, Illinois, under the jurisdiction of the state regulatory agency. For water resource and climate enthusiasts, Old Tom Creek WS Str 24 stands as a testament to the importance of sustainable water management practices in mitigating natural disasters and safeguarding communities against the impacts of changing climate patterns.

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 24
Where does the data for Old Tom Creek Ws Str 24 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.
