Pima-Maricopa Irrigation Project (Gila Rivier Indian Community)

The Pima-Maricopa Irrigation Project (PMIP) is the agricultural component of the Gila River Indian Community's Master Plan for Land and Water Use. Under this Master Plan is the development of a large distribution system designed to convey 173,100 acre-feet of water annually to 146,300 acres if rehabilitated existing agricultural lands and new agricultural lands as part of a Indian Water Rights Settlement. This distribution system will consist of open channel conveyance, check structures, flow measurement structures, turnouts, settling basins, siphons, road crossings, pump systems, wells, and multiple other irrigation delivery components. This monumental project is currently the single largest agricultural development project in the United States and will take many years to complete.
