The subject Arizona Department of Water Resources (ADWR) report is a thorough preliminary effort at determining how much water is needed to irrigate all practicably irrigable acreages (PIA) on the Gila River Indian Reservation (GRIR). ADWR identified 178,880 acres suitable for irrigation. An existing Gila River Indian Community (GRIC) Master Plan previously identified 146,330 acres suitable for irrigation (requiring 771 ,600 acre-feet of water per year). ADWR compared the two sets of acreages, and identified 129,030 acres common to both.
