There are several rapids in this section. This description is based on running it at 920 cfs. At said level I would say this section is a CL3+, but I can see how at higher water this could become CL4.  The real fun begins at Denton falls where the character of the river changes for the next 1.5 - 2 miles. No real big holes to worry about at Denton falls. but you need to pick your way down. We scouted on river right when we saw the first horizon line, Denton Falls. Once you get to Denton Falls  the gradient picks up and the river will get more narrow in places causing the water to get deeper which creates bigger waves and holes. With exception to Denten Falls and High Falls what looked liked horrizon lines disappeared as we got closer so boat scouting sufficed until high falls. At high falls we scouted on river right and was easily able to see our left line. Scouting from the left may prove to be tricky and perhaps a poor choice. We chose a far river left boof. We followed this creeky line which is seperated from the the rest of the river (at least at 920 cfs). Following this creeky section it takes a hard right so we followed the flow around the right turn and driving right to not to get pushed to far left, and boofed into the meat that almost looks like a hole but is not. The trick is when pushing right don't point to much to the right and go over sideways. Two people on my 2nd trip down got stuck for a bit. As long as your kayak is pointed12 or 1 o'clock , you should be fine.  We would dive into the water, submerge, and it felt like a big hand pushed me out and upward. A lot of fun. After high falls, the River turns to it's previous character, tame in comparison.  

 The rest of the way down after High Falls is a lot of CL2, mabe two more CL3 rapids and some flat water.

 BTW, the first time down I parked at The hikers parking lot on Katrina Falls road. A bit of a hike in, a quarter mile I guess.  Take the blue trail to the first yellow trail on your left. It's worth it if it's icey since we were were able to sliegh ride some portions of the trail which was also fun. I don't know if I would put in this way on a hot day, but it sure cuts off a lot of flat water, mabe a mile and a half of mostly flat.
