Windfall Lake Dam dam
Windfall Lake Dam
Windfall Lake Dam, located in Catlin, Illinois, is a privately-owned structure built in 1964 for recreational purposes along Windfall Creek. This earth dam stands at a height of 14 feet and has a length of 300 feet, with a storage capacity of 189 acre-feet. The dam is regulated by the Illinois Department of Natural Resources and is inspected regularly to ensure its safety.
With a low hazard potential and a moderate risk assessment rating, Windfall Lake Dam is considered a relatively safe structure. The dam features an uncontrolled spillway and outlet gates, with a spillway width of 79 feet. While the condition assessment is not available, the dam is inspected every five years to monitor its integrity. Despite its age, the dam continues to serve its primary purpose for recreation in the area, offering a picturesque backdrop for water resource and climate enthusiasts to enjoy.
Overall, Windfall Lake Dam is a vital part of the local landscape in Vermilion County, Illinois, providing both recreational opportunities and a source of water storage. With its controlled state jurisdiction and regular inspections, the dam remains a reliable structure for the community. As a key feature along Windfall Creek, the dam symbolizes the intersection of human engineering and natural resources, making it a fascinating site for those interested in water management 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 Windfall Lake Dam
Where does the data for Windfall Lake 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.
