I am guessing that in a court battle, it's likely that the stream I live on would be deemed navigable in fact, at least near its mouth, which as I understand would then mean all the way to its headwaters.
If it were deemed navigable in fact, you'd be correct on the all the way to the headwaters part. Any part of it that carries the same official stream name.
I would posit that even if you think you are legally in the right, the fair and ethical thing to do if you are going to fish your way through posted property would be to ask the landowner for permission or at least to inform them you plan to fish through feet wet.
Disagree.
IF you owned the streambed and didn't post, then I'd agree, the ethical thing would be to ask the landowner, even though I could legally fish (in PA) without doing so. It's still ethical to ask here, and in other state's it's required, even if you don't post.
And IF you owned the streambed and do post, the ethical thing is just to stay away. I'm assuming, of course, that the signs say "No Trespassing" and not "Ask permission before entry." Your responsibility is to accurately express your intent through signage. My responsibility is to adhere to what the signs say. If I just read "no trespassing", I'd assume you also do not want someone knocking on your door all the time. Besides, I'd have to trespass to get to your door....
But if it's navigable, you don't own the streambed. YOU ARE NOT THE LANDOWNER. And there's no ethical requirement for me to ask you before entering land that is owned by the public. That's utterly ridiculous.
Of course, I have to be sure not to leave public land and enter yours.
(and I say this having no idea what stream it is and whether it is navigable, so I'm not saying it is).
Since it's an open question on whether it's navigable, even though you may own both banks without question, you don't know whether you own the streambed itself. And you should have as much risk in "assuming" ownership as a fishermen has in "assuming" ownership and trespassing. If you were taken to court and lost, the situation is exactly the same as if you had put "No trespassing" signs up around your deer stand in the middle of State Forest, as you tried to exclude the public from public land.
Spring Creek? Navigable, in my opinion. Are parts of it posted by private citizens? If so, have at it.
Yes.
1. City of Bellefonte posts it in town. Not sure on legalities here, I assume it's with permission of the PFBC, or maybe even officially BY the PFBC.
2. On the upper end of this section, there's a few landowners who post.
3. Right below Paradise, there's a VERY short posted stretch, cables and fences and all.
4. There's some posted ground up in Houserville and Lemont.
5. Right at the source, there's a Quarry who posts.
