Summary
With a height of 27 feet and a length of 280 feet, the dam holds a maximum storage capacity of 38 acre-feet and a normal storage capacity of 27 acre-feet. The dam, situated on the tributary stream of Court Creek, serves as a popular spot for outdoor enthusiasts seeking recreational activities such as fishing, boating, and wildlife observation.
Managed by the Illinois Department of Natural Resources, Shebb Oaks Lake Dam has a low hazard potential and a moderate risk assessment rating of 3. The dam features an uncontrolled spillway with a width of 59 feet and outlet gates that are also uncontrolled. Despite its age, the dam has not undergone any recent condition assessments, and its emergency action plan status and risk management measures are not available. With its scenic location and recreational offerings, Shebb Oaks Lake Dam continues to attract visitors and contribute to the local ecosystem in Elmore, Illinois.
As an integral part of the Rock Island District, Shebb Oaks Lake Dam stands as a testament to the importance of water resource management and climate resilience. While its condition assessment and emergency preparedness could be improved, the dam remains a valuable asset for both recreational enjoyment and environmental conservation. With its peaceful surroundings and diverse wildlife habitats, Shebb Oaks Lake Dam serves as a reminder of the crucial role that sustainable water infrastructure plays in supporting communities and fostering a healthy ecosystem for future generations to enjoy.

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.
