Illinois

Seeing as how the put-in for this run is less than an hour from my home I've managed to get on this run a no. of times, both raft supported and self-supported in my kayak but mostly self-support kayak trips. I favor lowish flows and all my trips have been made between 450cfs to 1,250cfs @ Kirby. 450cfs goes fine for kayaks, but rafts will have a tight time in the lead-in and rocky exit in 'Green Wall' and the narrow exit at 'Submarine Hole' at 700 or lower. At 500 and lower 'Sub Hole' becomes a steep 4+ boulder garden, starting on river right and ending on river left, don't miss the move as the sub hole rock (6'-8' above the water at this flow) has some scary logs trapped on the right side of it. It's worth a scout from river right before running at low flows. Also of note is the entrance to York Creek rapid gets narrow and very steep at 500cfs and lower with a sticky hole in the center, so pick a side of the pourover and paddle!
