Colorado River study means it’s time to cut water use now, outside experts say
Less water for the Central Arizona Project — but not zero water. Even more competition between farms and cities for dwindling Colorado River supplies than there is now. More urgency to cut water use rather than wait for seven river basin states to approve new guidelines in 2025 for operating the river’s reservoirs. That’s where Arizona and the Southwest are heading with water, say experts and environmental advocates following publication of a dire new academic study on the Colorado River’s future. The study warned that the river’s Upper and Lower basin states must sustain severe cuts in river water use to keep its reservoir system from collapsing due to lack of water. That’s due to continued warming weather and other symptoms of human-caused climate change, the study said.
