About 5-6 weeks back I had three water snakes on frogs on Lake Bastrop. None of them got the hook from what I could tell. I pulled all three a distance towards the boat trying to get them off. The one that reached the boat was definitely a cotton mouth. He was pissed and seemed to just be holding on to the plastic. Unfortunately for me he came off right at the boat. Fortunately for me he struck the decal(I think) on the side of my boat and headed back to the reeds after some tense moments. I had my dog with me and fortunately he was bored with fishing already and sleeping on the other side of my boat.
Each time I ripped my solid body frog off the hook with a pair of pliers. I wasn't sure if there was any venom in or on the plastic, but I figured if there was with the cuts in my hands from fish that it wouldn't be a good combination.
That was an odd day. There were snakes everywhere, and I didn't see one single duck (mud or otherwise) the entire day. Bastrop normally has hundreds of ducks on it.
