I'd be willing to bet Arizona is also one of them. Doctrine of Prior Appropriation rules in most western states. Somebody 100 years ago filed for water rights on a stream that the runoff from your roof feeds. If you store it, you've appropriated someone else's water for your use. Rain barrels are common and, by and large, ignored under the "deminimis" principle. But a pond might be a different matter and get attention as an illegal impoundment.
