"Thanks for your thoughts. I've read that venomous snakes swim with most of their body ON the water and non venomous snakes will swim with just their head out of the water. Everything that I saw today was with most of their body on TOP of the water."

Every snake I've killed in the water was swimming on top. The only one I've ever seen whose entire body was on top was a rattler. If a water moccasin was 4' long, I doubt seriously he would be running off. I dont think they get that long. 3'...occasionally....maybe, but I've never seen one much over 30". One of my best friends in high school was killed when his water-ski hit a breeding ball of moccasins. They never saw the first snake until he fell into them.
