I am voting "No" as well because of the land ownership deal. But perhaps there is a middle ground here somewhere. How about grandfather rights to use power boats if you are a landowner? Make it drift only but include that one exception. I don't know, it is an issue that could open a can of worms.
I know of no cabins above the cabin on the north side of the river accross from where the Killey comes in.
I will look at borough maps and double check though, but the area in question would then be from the fist cabin private land below Skilak lake..
here is the link to the borough property ownership map, it clearly shows that the last cabin/ home going up river at the Keys, and directly accross from it is where personel property ends.
so the area in question would of course be from that point on up stream to the skilak out areas.
