At flows below about 1500 cfs, this rapid has a sticky hole at the bottom wedged between the river left eddy and the rock wall on river right. It's easy enough to avoid by driving left, but if you get stuck in the hole, be prepared for a ride. At medium to high flows, this rapid is straightforward and the hole at the bottom disappears.
The name Dick's Overhang refers to kayak legend and surf ski wizard, Dick Wold, who must've taken a memorable ride in the hole back in the day.
