Completed in 1972, this earth dam stands at a height of 26 feet and stretches 1,110 feet across the West Branch DuPage River. With a primary purpose of flood risk reduction, Fawell Dam has a maximum storage capacity of 3,172 acre-feet and can discharge up to 23,577 cubic feet per second through its controlled spillway.
The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections, with a hazard potential rated as high. Despite its age, the condition assessment of Fawell Dam is currently not available, indicating a need for further evaluation and potential maintenance. The Emergency Action Plan (EAP) for the dam was last revised in 1999, highlighting the importance of ensuring the readiness and effectiveness of emergency response measures in the event of a dam failure.
Given its location and the significant risk it poses, Fawell Dam has been assigned a very high risk assessment rating. With Sean Casten representing the area in Congress, stakeholders and water resource enthusiasts should monitor developments related to the dam's safety and management measures to mitigate the potential impacts of a catastrophic failure on the surrounding communities and the environment.
