Gebhardt Lake Dam dam
Gebhardt Lake Dam
Gebhardt Lake Dam, located in Swansea, Illinois, is a privately owned structure that serves primarily for recreation purposes. 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.

About Gebhardt Lake Dam
Where does the data for Gebhardt Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.
