Arizona will take nearly a $3 trillion total economic hit and lose millions of jobs that would have come to the state by 2060 if Central Arizona Project deliveries are halted by the federal government, a new report from the project’s governing agency says. A CAP consultant’s report said the state’s total economic output would by 2060 be 11% to 14% lower than it otherwise would have been, under two proposed federal alternatives for managing the Colorado River. At worst, the state’s total jobs would shrink by 7.9% if the project’s supplies were eliminated, the report said. In addition, the state would see substantial declines in population and housing growth by then with massive CAP cuts, compared to what would have happened without them, said the report.
The three-county agency that runs the CAP’s canal system, stretching from Lake Havasu on the Colorado River to just south of Tucson, commissioned this report from the consulting firm WestWater Research, based in Boise, Idaho. The agency, known as the Central Arizona Water Conservation District, has managed daily operations for CAP since it was under construction in the 1970s. CAP submitted this report as part of its comments sharply criticizing the U.S. Bureau of Reclamation’s draft environmental impact statement on proposed alternatives aimed at curbing excessive water use by cities and farms in the seven-state Colorado River Basin. It comes out shortly after project officials released a video warning that such cuts would “flatten” Arizona’s economy. At the time the video came out, some outside water experts said it oversimplified and overestimated the impacts of CAP cuts, in part because the state and local governments have already stored huge amounts of CAP water underground to prepare for such emergencies. But the new report says those supplies will eventually be exhausted, forcing many cities to return to groundwater pumping, and that some shortages of groundwater supplies themselves also could begin in some regions as soon as the early 2030s.
