In late summer, I made two trips down the DuPage River, specifically the rapids section. Spanning from Hammel Woods to Channahon State Park, it is a 10 mile stretch with many twists and turns, and rapids. The height was pretty low, measured at 2.5-3 feet both times at the shorewood USGS gauge
Here's another video of the rapid section in full.
