This is why I fish water on publicly owned land almost exclusively, with a few well known as being open to fishing exceptions…generally bigger STW’s or stocked Class A’s. I haven’t run out of new public water I’m interested to try yet, and don’t imagine that I ever will.
I don’t want to deal with this kind of bologna while fishing. Everyone with a youknowwhat hole has an interpretation of the whole signage/navigable/public/private thing. It’s a calculated risk (of varying degree) any time you fish on privately owned land. The only time I’ve been run off a stream it was completely unposted, and prior to the purple paint rules. I’m not 100% convinced it wasn’t a tenant, and not the owner who ran us off too. Still, that was the last time I fished anywhere I wasn’t 100% sure of. 10 years ago probably.
Fishing is fun. Having philosophical access discussions with landowners and/or law enforcement, or on a fishing forum, is not.
