Summary
Constructed in 1940 by Midwest Coal Co., this earth dam stands at 37 feet tall and spans 570 feet in length. Its primary purpose is for recreation, with a storage capacity of 632 acre-feet and a normal storage level of 177 acre-feet.
Situated on Trib Prairie Dupont Creek, Davis Lake Dam is regulated by the Illinois Department of Natural Resources and undergoes state inspection and enforcement. With a high hazard potential and a moderate risk assessment rating, emergency action plans were last revised in 1990. The dam features an uncontrolled spillway with a width of 34 feet, and outlet gates are also uncontrolled.
Water resource and climate enthusiasts will find Davis Lake Dam an intriguing structure to study, given its historical significance and impact on the surrounding environment. With its high hazard potential and moderate risk assessment, understanding the safety and maintenance of this dam is crucial for ensuring the protection of both the local community and natural resources.

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.
