Idaho river access laws

[idahoron]

The snake river has a lot of private owned islands. The no trespassing signs are normally posted right on the waters edge in late summer. I would think that the high water water mark would be much higher. I don't go on the islands at all. I was standing in the water and my boat was pushed so the front was touching the sand. I had a guy yell at me for getting off. I told him to call the sheriff I would wait. No cops ever showed up. Ron
