Funny you bring that up, the west side was not posted well and the east side looked very well used and partied upon two weeks ago when I was up driving around looking at places I used to fish 30 years ago. There is a cable across the stream about 100yds below the bridge.
In my county, I can't press trespass charges for a game cam pic clearly showing a vehicle and license plate with a driver, .3 mile down a private lane past 2 clear "No Trespassing" signs approaching a dead end at a home. My response, no law against driving down a road???
But, I can shoot them if I feel my life is in danger and need to protect myself, property, or family.
