When I was a kid a bunch of the old timer's would take boats upriver from New Lisbon and cut all the overhanging trees that were blocking the way upriver. I helped them for about 4 years, until enough of them quit doing it that we just gave up on it. You could take boats way up past your place, just as long as the water was high enough to float your rig. I'm not sure how passable those upper areas are anymore, I haven't been on the river for years.
