Gebhardt Lake Dam Reservoir Report
Last Updated: February 6, 2026
Gebhardt Lake Dam, located in Swansea, Illinois, is a privately owned structure that serves primarily for recreation purposes.
Summary
Situated along TRIB RICHLAND CREEK, this dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance with state regulations. The dam has a high hazard potential, indicating the potential risks associated with its failure.
Although specific details such as dam height, volume, and completion year are not provided, the dam's hazard potential and moderate risk assessment highlight the importance of proper management and maintenance. The Emergency Action Plan (EAP) for Gebhardt Lake Dam was last revised in April 2021, emphasizing the need for preparedness and adherence to safety guidelines in case of emergencies. With a hazard potential rating of 'High' and a risk assessment of 'Moderate (3)', it is crucial for stakeholders and local authorities to stay vigilant and prioritize the safety of the surrounding area.
Despite the limited information available, Gebhardt Lake Dam's significance lies in its role in providing recreational opportunities while facing potential risks associated with its high hazard potential. By staying proactive in risk management measures, maintaining regular inspections, and ensuring that emergency protocols are up to date, the safety and integrity of Gebhardt Lake Dam can be preserved for water resource and climate enthusiasts to continue enjoying its benefits.

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.
