Summary
Built in 1994 by MCCLURE ENGINEERING ASSOCIATES, INC, this Earth dam stands at a height of 62 feet and spans a length of 575 feet, providing a storage capacity of 365 acre-feet. With a surface area of 15 acres and a drainage area of 0.09 square miles, the dam plays a crucial role in managing water resources for the local ecosystem.
The dam, regulated by the Illinois Department of Natural Resources, has a high hazard potential due to its proximity to the TRIB LITTLE MILL CREEK. Despite its condition assessment not being available, regular inspections are conducted to ensure its integrity. The spillway, with a width of 95 feet, is uncontrolled, allowing for a maximum discharge of 1030 cfs. With a risk assessment rating of moderate, the dam is equipped to handle potential emergencies, although specific risk management measures are not detailed in the data.
For water resource and climate enthusiasts, Doyle Lake Dam presents an intriguing case study in dam infrastructure and management. Its role in supporting fish and wildlife habitats, recreation, and water storage highlights the importance of sustainable water resource practices. As climate change continues to impact water availability and quality, understanding the design, operation, and regulation of dams like Doyle Lake Dam is essential for ensuring the resilience of our water systems in the face of evolving environmental challenges.

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.
