I currently have a Northern Water snake in my pond. Very neat looking snake. Worried me at first as I thought water moccasin till I looked it up. He's about 3" long and been in there for a couple months now. Earlier in the year I found hundreds of Mud Puppies all no more than a 1" long. Never seen these in the wild, only know of dissecting them in Biology class as a kid. I think they are still there but not seen them. The odd is that I don’t have one frog this year and not had any turtles. If I find a turtle and put him in do you think he will stay?
