Things like that, or killing it if it was near kids. Since the snake won't go after people I would just not let the kids play near the snake rather than killing it.
I just can't see a situation where the snake would be between you and a child and you would have to swoop in and kill the snake when you could much more safely remove the child than try to kill the snake risking both you and the child.
The exception being the person who lives by the lake, because that is a permanent problem.
