Arizona actually has a lot of water because of several successful and ambitious irrigation projects in the last century.
So much so, that it has become an agricultural region for growing notoriously water intensive crops like alfalfa and pistachios.
It's notoriously unsustainable. Those water intensive crops would be wildly infeasible if the farmers had to pay anything close to a market price for the obscene amounts of limited water they consume.
