This reach contains a good number of marked, named rapids. The majority would appear to be low-grade (class I-II) boulder-bed type rapids.
The Flambeau has a long stretch of mild whitewater, allowing multi-day runs. To accommodate this, there are numerous streamside 'canoe campgrounds'. One such campground (apparently also accessible by roads) may be used to divide this section into two shorter sections.

Drainage area at our listed put in is about 1,000 square miles (as calculated by USGS StreamStats beta software). By the listed take-out of this long section, drainage has increased to 1,800 square miles (an 80% increase ... nearly double).

Listed on the topo maps at this location is a 'canoe campsite', which appears to be accessible by road as well. It appears this could serve as an alternate put-in/take-out, making an 'upper' section of ~8.1 miles (consisting of the three Porcupine Rapids) and/or a 'lower' section of ~6.1 miles (consisting of the three Wannigan Rapids plus Flambeau Falls Rapids).

Just past Dodes Island (a pretty fair sized island in the river), you encounter Flambeau Falls Rapids. The confluence with the S.Fk.Flambeau lies not far downstream. The listed take-out for this reach will be about 2 miles downstream from that confluence.
