:Okay....but first, you gotta work with us just a leeetle bit. www stands for world wide web. Got that? Now...snakes all have certain ranges...that is, parts of the world, or the country or the state that they live in. They very seldom go far outside these ranges. So....the very first thing we have to know is where in the flippin' world your lake is.
Now, once you've done that for us, perhaps you might give us a little more detail on the snake, such as length & girth. Then I'll betcha somebody here can tell you exactly what it is.
