I`ve been told conflicting things on this issue, Some folks have told me it`s the high water mark, and that as long as you stayed below that, or if need be, wade through the stream to stay below the hm. Others have said if it flows through someones property you could float through but not get in the water because the property owner owned the land under the stream/river.

I`ve never been able to find a law that definitively states either way. It would be nice if they made a law that clearl defined it.
