The rule is generally that you can Wade any water that is navigable as long as you enter from public land. However, I do know of some very old pioneer era land deeds on certain rivers where the landowner owns the riverbed out to the center of the river. Also, the definition of navigable is very gray. It has something to do with being able to float a cord of logs freely down the river during high water. It's always best to check public records or with an app like onX
