What can be done about water damage created by a careless neighbor?

Again its going to depend on the law in you jurisdiction and exactly what the neighbor is done and what sort of damage it caused. If somebody has a stream across their property and they re-directed so that flows right into your back door you can expect that there is going to be liability on the neighbor who changed the flow the water. It's sort of general rule you just can't do unreasonable things like that. But it's going to depend on exactly what the law is in your state and what actions have been taken.
