Construction and operation of 40 miles of aqueduct from the terminus of the Salt-Gila Aqueduct in southcentral Pinal County to the vicinity of Rillito in northern Pima County, Arizona are proposed. The project, which would constitute Phase A of the Tuscon Aqueduct Project would involve three pumping plants; 40 miles of open, concrete-lined canal; two miles of discharge pipeline; and 29 miles of 115-kilovolt overhead transmission line. Approximately 185,000 acres of farmland in Pinal and Pima counties could receive water via Phase A of the Tuscon Aqueduct. As a result, the amount of water pumped from the groundwater aquifer in this area would decrease. Lowering of the aquifer level that results in increased pumping costs and damaging land subsidence would be mitigated by importation of water via the aqueduct.Rights-of-way requirements would displace pecan orchards, desert grazing land, and wildlife habitat, and the canal would obstruct wildlife movements and would constitute a drowning hazard for wildlife. Structures and rock cuts would mar visual aesthetics. Historic and prehistoric archaeological sites would be affected. The aqueduct would interfere with some small surfacewater drainages and water would be lost due to evaporation. Recreational access to the west side of the Picacho Mountains would be hampered somewhat.
