There are 22 federally recognized tribes in the state of Arizona. Of those tribes, fourteen (14) have either, fully resolved, adjudicated rights or partially resolved water right claims and of that group, a number of those tribes received a significant portion of their water through the CAP. Going forward, the 2004 Arizona Water Settlements Act set aside an additional 67,300 acre-feet of CAP water to address any remaining water rights settlement claims. In total, approximately 46% of the CAP water supply is or will be permanently allocated to Arizona Indian Tribes.  This makes CAP the largest single provider of Colorado River water to tribal water users in the Colorado River system.

As more tribes begin to take CAP water, the need to understand one another's operations will continue to grow. To meet this changing demand, CAWCD is proactively working with tribes and their communities to understand the different needs of each tribe and the unique challenges and opportunities impacting each tribe. The CAP was constructed out of a collaborative process and CAWCD believes it is through continued collaboration with the tribes that we can propel our desert communities forward.
