I would like to have a pond but am afraid of the cotton mouth snakes. I have a friend who was working on her water lilies and one huge snake chased her all the way to her house. Her husband finally shot it. And I found a huge fat one curled up in my overturned kayak. I put Pvc posts in ground hanging my kayak off the ground. When we turned it over it slid to the bottom of kayak and we just dropped it and ran. We have canals that drain storm water to Lake Washington in melbourne. I'm sure that's where it came from. I am not scared of snakes, love my black racer, but the cotton mouth is another story.
