Summary

Built in 1993 by ROBERT H. ANDERSON & ASSOC., this earth dam stands at a height of 9 feet and stretches 500 feet in length, with a maximum storage capacity of 60 acre-feet. The primary purpose of this dam is for recreation, offering a surface area of 10 acres for water enthusiasts to enjoy.

Managed by the Illinois Department of Natural Resources (IDNR), the Meridian Campus Liberty Road Dam has a low hazard potential and is inspected every five years to ensure its safety and integrity. While it has a moderate risk assessment rating, the dam has not had a recent condition assessment available. With an uncontrolled spillway and no outlet gates, this dam serves as a peaceful recreational spot for locals and visitors alike, nestled in the scenic DuPage County. Whether you're interested in water resource management or climate science, this dam is worth a visit to appreciate the intersection of human engineering and natural beauty.

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. 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

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, 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.
