When you think of water canals, you might think of Venice, Italy, Amsterdam in the Netherlands or even Venice, California. You probably don’t think about Phoenix. But metro Phoenix actually has more miles of canals than all three of those places combined.The city's canal systems are operated by the Salt River Project and the Central Arizona Project for the U.S. Bureau of Reclamation.
