Yeah I had the same problem at the power plant..........there are or were last time I was there big white cans that tell you to p*ss off. I would guess they are about 1/4 mile out surrounding the power plant........you can still fish beyond those though.........I remember the guy with the machine gun waving me off while trolling. It was about 1 minute before I hooked onto a 35" keepa!!
