CTH.B / N.Br.Suamico

To have a chance to explore the steepest gradient apparent on this river, the nearest available access point is on the North Branch of the Suamico.

Unfortunately, the final 1.25 miles of the North Branch meanders though heavily wooded area and may be more portaging than paddling.

However, once you reach the confluence with the main Suamico, it should be less prone to wood, and you will be on the ~1.5 miles leading into the put-in listed below. From aerial views, it is not apparent whether the river actually has any good features in this stretch ... it could fritter away the gradient without encountering any true rapids.
