Summary

Constructed in 1972 by Boon Engineering, this earth dam stands at a height of 53 feet and spans a length of 1085 feet. With a maximum storage capacity of 3950 acre-feet and a normal storage of 2870 acre-feet, Fyre Lake Dam has a significant hazard potential and is classified as having a moderate risk level.

Managed by the Illinois Department of Natural Resources, the dam is state regulated and undergoes regular inspections to ensure its structural integrity and safety. The spillway, with a width of 180 feet, is uncontrolled, and the outlet gates are also uncontrolled. Despite the lack of available information on the current condition assessment, Fyre Lake Dam remains a key feature for recreational activities in the area, offering a surface area of 155 acres and attracting visitors for various water-based pursuits.

Fyre Lake Dam, situated on the Trib Camp Creek, is a vital component of the local ecosystem and provides essential water resources for the surrounding area. With its historical significance and continued importance for both recreation and water management, this dam serves as a focal point for water resource and climate enthusiasts interested in the sustainable utilization of natural resources in Illinois.

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. 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

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, 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.
