I don't really see any other choice other than to get a better water bowl. I have some larger snakes that won't dump my little souffle bowls I use for the babies, but some babies will dump them. If you have a dollar store, or a dollar tree in your area go get one of the glass heart shaped water bowels, none of the snakes can dump those. Otherwise maybe you can find a dog bowl that gets larger towards the bottom, that keeps it from getting flipped. You can't keep using the bowl the snake is dumping, eventually you are going to end up with health problems.
