Summary
Completed in 2011, this earth-type dam stands at a height of 11.5 feet and stretches over 2,103 feet in length. With a storage capacity of 73 acre-feet, the dam plays a crucial role in mitigating the impact of flooding in the area, particularly along the TRIB KICKAPOO CREEK.
Managed by the local government and designed by THE UPCHURCH GROUP, INC., South Side Detention Basin Berm 1 Dam is under the regulatory oversight of the Illinois Department of Natural Resources. The dam's hazard potential is categorized as high, reflecting its importance in safeguarding the surrounding community from potential flooding risks. While the condition assessment is currently not available, regular inspections are conducted to ensure the dam's structural integrity and effectiveness in flood control measures.
For water resource and climate enthusiasts, South Side Detention Basin Berm 1 Dam serves as a testament to proactive flood risk reduction efforts in Illinois. With its strategic location and design, this dam represents a vital infrastructure component in the region's resilience against natural disasters. As climate change continues to pose challenges, the presence of such structures underscores the importance of sustainable water management practices to protect communities and ecosystems from the impacts of extreme weather events.

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.
