Lake Of The Woods Dam dam
Lake Of The Woods Dam
Lake of The Woods Dam, located in Peoria, Illinois, was completed in 1964 and stands at a height of 58 feet, with a length of 507 feet. The dam's primary purpose is recreation, providing a storage capacity of 378 acre-feet and a normal storage level of 233 acre-feet. The dam is privately owned and maintained, with state regulations and inspections in place to ensure its safety and compliance with standards.
The dam's design, by Austin Engineering Co., incorporates an earth core with buttress foundations. It features an uncontrolled spillway and outlet gates, with a significant hazard potential. The dam is located on the Trib Dickinson Run river, in the Mossville-Offstream area, within the Chicago District of the US Army Corps of Engineers. Despite moderate risk assessment, the dam's condition assessment is currently not available, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality for water resource and climate enthusiasts who frequent the Lake of The Woods area.
With its picturesque setting and recreational opportunities, Lake of The Woods Dam serves as a vital structure for the local community and visitors alike. While facing certain risks and challenges, the dam's role in providing water storage and recreational activities underscores its importance in the region. Continued oversight and management are essential to preserve the dam's integrity and ensure a safe and sustainable environment for all who enjoy the beauty of Lake of The Woods and its surrounding area.

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 Lake Of The Woods Dam
Where does the data for Lake Of The Woods 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.
