Interesting topic , when I was younger two of my buddies and I were standing in a tributary of Lake Ontario that was before the first barrier impassable by fish however both steam banks were posted. We thought because we were in a navigable water way we were ok , the land owner saw us and called the state police. The officer came down to the water and walked us back to our car and had us follow him to the troopers barracks where the Encon officer was waiting. The Encon officer explained the someone had recently shot the land owners pet ducks while they were in the creek and left them so he was pressing charges on anyone who was fishing there. Everyone was very good about it and I still have a picture of my and the largest steelhead I have ever caught standing in front of the troopers car before the Encon officer confiscated it. We received tickets and had to appear in town court. The judge fined us $10.00 each . What I remember the most was both the judge and Encon officer told us not to let this discourage us from our love of the outdoors.
