Summary

Built in 1993 by ROBERT H. ANDERSON & ASSOC., this recreational dam stands at a height of 9 feet and stretches 750 feet in length. Situated on the Waubansee Creek, it serves as a picturesque spot for outdoor enthusiasts to enjoy activities like fishing, boating, and birdwatching. With a maximum storage capacity of 70 acre-feet and a normal storage level of 6 feet, the dam offers a serene setting for visitors to relax and unwind.

Managed by the Illinois Department of Natural Resources (IDNR), the Meridian Campus Lake 7 Dam has a low hazard potential and is inspected every 5 years to ensure its safety and structural integrity. Despite its moderate risk assessment rating, the dam has no documented condition assessment available. The spillway, with a width of 20 feet, is uncontrolled, providing a scenic overflow for excess water during periods of heavy rainfall. The dam's location in Aurora, Illinois, makes it easily accessible for locals and tourists looking to appreciate the beauty of nature while also appreciating the engineering marvel of the structure.

While the Meridian Campus Lake 7 Dam may not be widely recognized, its role in providing recreational opportunities and maintaining the water levels in Waubansee Creek is significant. With its tranquil surroundings and well-maintained facilities, this earth dam stands as a testament to the harmonious coexistence of human infrastructure and natural beauty in the heart of Illinois. For water resource and climate enthusiasts, a visit to this hidden gem offers a chance to appreciate the delicate balance between man-made structures and the environment they inhabit.

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.
