Summary
The dam is classified as an Earth type structure, standing at a height of 175 feet and spanning a length of 9700 feet. With a storage capacity of 15,942 acre-feet, the dam is regulated by the Illinois Department of Natural Resources and is subject to regular inspections and enforcement measures to ensure its safety and compliance with state regulations.
Despite its significant hazard potential, the current condition assessment of the Refuse Disposal Area is not available. However, the dam has not had any Emergency Action Plan (EAP) prepared or updated, raising concerns about its readiness in case of an emergency. Furthermore, risk assessment and management measures for the dam are also not specified, leaving room for improvement in terms of ensuring the safety and effectiveness of the structure. As a key water resource in the area, it is crucial for stakeholders to prioritize the monitoring and maintenance of the Refuse Disposal Area to prevent any potential risks or hazards to the surrounding environment and community.

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.
