That's good, since it sounds like there's less water available than there was in the 50s. Still, it strikes me that even if Arizona isn't itself a disproportionate consumer, being between the water source and even larger consumers (i.e. Southern California) it's set up to be in a tough position.

Also, regardless of water availability, the other concerns of climate change are going to affect people living there. There are substantial wildfires every year, and not all that far from (expanding) communities in the Phoenix area, for example.
