Boulder gardens and a couple ledges make a fun run at high water. Mostly, action is pretty sparse
until the river takes a big bend near Hwy.73 (where Jack Creek / Cunningham Creek meets this
reach). At this point a significant ledge can provide some play. A fine dells/rapids (rocky
walls) finishes the reach just below Hwy 95.
(Note: Observations and 'minimums' based on only one run at 1290cfs.)
Following is a YouTube video which (I'm quite certain) shows someone canoeing down the most
significant ledge/drop on this reach.
Listed minimum is for 'experienced' whitewater boaters. The reach is floatable much lower, but will generally be (again, for experienced whitewater boaters) a tame 'rock-dodge' run. (This may cause canoeists who are not experienced in whitewater, or boaters who do not have appropriate whitewater craft, to consider this reach very difficult and near scary at most water levels!)

can be tricky/frustrating but definitely runnable. Between 750 and 1200 seems best with lots of
"textbook" features developing. 1250 is mostly washout haystacks. I have never run it above 1250
nor beyond hwy 95.
