If you have a pond around here you will have snakes. Water Moccasins are our only poisonous snake and pretty common. The small pond is only 30 feet from our front door and I spent a lot of time out there mowing, feeding fish, or just loafing. I would occasionally see a snake and killed them because we have small grandkids that play out front and didn't want them bit by any snakes in the grass. When the pond got low last year as I was draining it, I killed 3 water moccasins, 2 brown water snakes, and a red snake of some sort. I had no idea the moccasins were there. I only shoot moccasins in the pond across the road.
