I would agree with Neil on this one. Again, as long as you are in the vessel you are fine. There are a few landowners who own the stream bottom as part of their property. If you've done your research and know where those properties exist, kudos to you for doing the research, but don't get out of your boat. I'm not aware of too many situations where the property owner has come out and forced people out. Respect the landowners wishes and move on if they do confront you. Avoid confrontation. Also on a slightly different note, be mindful that a law was passed last year stating "on bodies of water with a 10 HP limit and between 1 hour before sunrise to 1 hour after sunset, no Safe Boating Certificate is required for a person operating a vessel with an electric motor (rated at 106 lbs of thrust or less) however the vessel must be registered.
