Greenstone Acquisitions, which holds a Colorado River diversion water entitlement of 2,913.30 acre-feet per year (AFY) for irrigation use in the name of GSC, proposed to permanently assign and transfer to Queen Creek, GSC’s estimated consumptive use of its Colorado River water entitlement of 2,083.01 AFY. Queen Creek has a Central Arizona Project (CAP) municipal and industrial water subcontract for 495 AFY with the United States and the Central Arizona Water Conservation District (CAWCD) and would need a CAP wheeling agreement to convey the transferred non-project water to its service area. The proposed water transfer would entail a change in the place of use, type of use, and change in the present point of diversion from the Cibola Valley Irrigation and Drainage District where the GSC lands are located, to a diversion at the Mark Wilmer Pumping Plant for conveyance through the CAP to Queen Creek.
