The one time I'll actually say thank God I live in Minnesota... lol. Here unless the body of water is completely on your property, it's wide open for all too use as long as there is an access too it from somewhere public. If not, say a pond for example, those with land connected to the body of water have access. In the case of this specific river, I drop in at a kayak access point, and as I go up river the public that is land locked is still on the East side of the water where it's still accessible by water, but is no longer accessible on foot. I think in the case of this river, any state should be safe because you're always within arms reach of the public land from the water.
