Bazzoni Lake Dam dam
Bazzoni Lake Dam
Bazzoni Lake Dam, located in Marseilles, Illinois, is a private dam primarily used for recreational purposes. Built in 1989 by McClure Engineering Associates, this earth dam stands at a height of 65 feet and spans 200 feet in length. Situated on the Tributary of Illinois River, this dam has a maximum storage capacity of 40 acre-feet and a normal storage capacity of 25 acre-feet.
Managed by the Illinois Department of Natural Resources, Bazzoni Lake Dam has a low hazard potential and a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 12 feet and outlet gates that are also uncontrolled. Inspected every 5 years, the dam's condition assessment is currently listed as "Not Available." While the dam meets state regulatory guidelines and undergoes regular inspections, there are no emergency action plans or inundation maps prepared for this structure.
Water resource and climate enthusiasts will find Bazzoni Lake Dam to be an interesting site for its recreational purpose and the engineering challenges it presents. With its proximity to the Illinois River and its low hazard potential, this dam serves as a key feature in the local landscape and contributes to the overall water infrastructure in LaSalle County, Illinois. Despite its risk assessment, ongoing management and inspection ensure the safety and integrity of this essential water resource structure.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Bazzoni Lake Dam
Where does the data for Bazzoni 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 below 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.

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.
