Basswood portages are all easy.....Upper Basswood portage is a mile long....but a flat walk.  Couple of places you can cut it off at 3/4 mi or 4/5 mi depending on water flowage and your desire to "shoot" some smaller rapids.  Careful....some have drowned here.  You have to side trip off the trail to see the upper falls.  IMO, the lower falls are more picturesque.

Wheelbarrow falls can be portaged, or you can paddle the N side of the isle (Canadian side) and take the easier portage back S to the river (check your map).

Man, I gotta do that Ranger bay--Kett trip sometime.
