Summary
Built in 1959 by Rochester & Goodell, this private earth dam stands at a height of 22 feet and spans a length of 490 feet, with a storage capacity of 160 acre-feet. The dam is situated on the Trib Jims Creek, providing a picturesque backdrop for outdoor activities such as boating, fishing, and picnicking.
Managed by the Illinois Department of Natural Resources, the dam is regulated and inspected regularly to ensure its safety and functionality. With a low hazard potential and moderate risk assessment, the Rochester-Goodell Reservoir Dam is deemed to be in stable condition. In the event of an emergency, the dam has an uncontrolled spillway and outlet gates in place, with updated emergency action plans to mitigate potential risks.
Enthusiasts of water resources and climate in the region can appreciate the Rochester-Goodell Reservoir Dam for its contribution to the local ecosystem and recreational opportunities. As a well-maintained structure with a focus on safety and environmental impact, the dam continues to play a significant role in providing enjoyment and conservation benefits to the community of Carlyle and beyond.

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.
