Summary
Standing at a height of 25 feet and spanning 230 feet in length, the dam has a storage capacity of 64 acre-feet, with a normal storage level of 38 acre-feet. Situated along the tributary of Walnut Creek, the dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and safety.
With a low hazard potential and a moderate risk assessment rating of 3, Kepler Lake Dam is deemed to pose minimal risk to downstream communities in case of a breach. The dam features an uncontrolled spillway with a width of 10 feet and outlet gates that are also uncontrolled. Despite its low hazard potential, the dam's emergency action plan status and risk management measures are not available, highlighting a potential area for improvement in emergency preparedness and response should the need arise. Overall, Kepler Lake Dam serves as a vital recreational asset in the region while also being closely monitored for safety and compliance with regulatory standards.
Managed by private owners, Kepler Lake Dam offers a picturesque setting for outdoor enthusiasts and nature lovers to enjoy. Its location in the city of Elmore, Illinois, makes it easily accessible for visitors seeking recreational activities such as fishing, boating, and hiking around the scenic lake. With its tranquil surroundings and well-maintained facilities, Kepler Lake Dam remains a popular destination for those seeking a peaceful escape in the heart of Stark County.

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.
