Summary
The dam stands at 15 feet high and stretches 325 feet in length, with a storage capacity of 80 acre-feet. Its spillway, with a width of 7 feet, is uncontrolled, and the dam is regulated by the Illinois Department of Natural Resources, undergoing regular inspections.
Situated on TRIB SUGAR CREEK, Eads Lake Dam poses a significant hazard potential, with a moderate risk assessment rating. Despite its age, the condition assessment is not available, and the emergency action plan status is unknown. The dam has a drainage area of 0.2 square miles and a maximum discharge capacity of 75 cubic feet per second, serving as a vital water resource in the region.
Water resource and climate enthusiasts will find Eads Lake Dam a fascinating structure that contributes to the recreational landscape of Edgar County, Illinois. With its earth core and buttress design, the dam's impact on the surrounding environment and its potential risk management measures make it a noteworthy site for further study and monitoring.

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.
