Summary
Built in 2011 by THE UPCHURCH GROUP, INC., this earth dam stands at a height of 13.65 feet and has a length of 2002 feet, providing a storage capacity of 69 acre-feet. The primary purpose of this dam is to mitigate flooding along the TRIB KICKAPOO CREEK, serving as a vital component in the region's water resource management.
Managed by the local government and regulated by the Illinois Department of Natural Resources (IDNR), South Side Detention Basin Berm 2 Dam has a low hazard potential and a moderate risk assessment rating. While its condition assessment is currently unavailable, the dam undergoes inspections every 5 years to ensure its structural integrity and operational efficiency. Despite being a relatively new structure, the dam plays a crucial role in safeguarding the community against potential flood events, highlighting the importance of proactive water resource management in the face of changing climate patterns.
With its uncontrolled spillway type and lack of outlet gates, South Side Detention Basin Berm 2 Dam represents a key piece of infrastructure in the region's flood protection system. As climate change continues to impact water resources, the maintenance and upkeep of structures like Berm 2 are essential for ensuring the safety and well-being of local residents. By staying vigilant and proactive in monitoring and managing these critical assets, communities can better adapt to the evolving challenges posed by a changing climate.

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.
