I have broken dams to hunt them. Don't shoot the first one that is the scout. It will go back and get some buddies to help then you shoot.
I caught a big female in a trap one time in a river and.she wasn't drowned. I ended up shooting 2 of her kits and a couple of grown ones when I ran the boat up to her. I didn't recover them but They just popped up and I kept shooting them in the head close by. I guess she was in heat. Never had that happen again.
