Summary
Built in 1941 by FOTH & VAN DYKE, this earth dam stands at a height of 36 feet and stretches 365 feet in length. With a storage capacity of 240 acre-feet, the dam serves as a recreational hub for the surrounding area, offering a serene escape for water resource and climate enthusiasts.
Managed by the Illinois Department of Natural Resources (IDNR), Fox Ridge Lake Dam is regulated, permitted, and inspected by the state to ensure its safety and functionality. The dam's spillway, of uncontrolled type, has a width of 81 feet and a low hazard potential. Despite its moderate risk assessment, the dam has not undergone a condition assessment and is labeled as "Not Available" in terms of its current condition status.
Situated along the tributary Embarras River, Fox Ridge Lake Dam presents both environmental and recreational opportunities for visitors. With its picturesque setting and historical significance, the dam continues to be a vital part of the local community and a focal point for water resource and climate enthusiasts to explore and appreciate.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
