Deer Park Lake Dam dam
Deer Park Lake Dam
Deer Park Lake Dam, located in LaSalle, Illinois, is a private-owned structure completed in 1910 primarily for recreational purposes. Situated along the TRIB Vermillion River, this arch-type dam stands at a height of 55 feet and spans 125 feet in length, with a storage capacity of 314 acre-feet. Despite being privately owned, the dam is regulated by the Illinois Department of Natural Resources, ensuring that it meets state inspection and enforcement standards.
With a hazard potential categorized as "significant" and a moderate risk assessment rating, Deer Park Lake Dam poses potential risks that need to be managed effectively. The dam's spillway type is uncontrolled, with a width of 57 feet, and it has uncontrolled outlet gates. The last inspection was conducted in July 2018, with a frequency of every three years. While the condition assessment is not available, the dam's risk management measures and emergency action plan status are also unspecified.
This historic dam not only serves as a recreational spot but also contributes to water supply needs in the area. As water resource and climate enthusiasts, monitoring and ensuring the safety and structural integrity of Deer Park Lake Dam is crucial to prevent any potential risks and protect the surrounding community and environment.

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 Deer Park Lake Dam
Where does the data for Deer Park 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 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.
