In that case if you could "float" on the water's surface, without touching the land on the bottom, you would be within your legal rights. You could be inches from private property shoreline and as long as you don't touch the underwater channel, you're good. It is navigable waters.
There is a spot near Seven Oaks where this little "battle" takes place all the time. I don't if this is where the OP is talking about, but in this instance the landowner is in the right. It private property within the National Forest. You can't avoid the land since the water is not navigable. Fish and Game and the SBSO are usually called when the "battle" get's a bit heated.
Bottom line; just remember the navigable waters stuff. Even if water flows over PP you can't trespass on it-but you can float over it! Hope this helps.
