Water is Arizona's most precious resource and the Colorado River satisfies much of the demand. The 335-mile-long Central Arizona Project (CAP) canal continually conveys Colorado River water to Maricopa, Pinal, and Pima counties in central Arizona. While delivering water is a core element of CAP's mission, CAP also ensures all of Arizona's entitlement is put to beneficial use in Arizona. Water that is not directly used can be stored underground to offset groundwater overdraft or stored to be recovered at a later date, according to Arizona's groundwater code.
