The decision to step back from cloud seeding could impact Arizona's water supply, as snowmelt from the Rockies is critical for replenishing the Colorado River. CAP board members expressed skepticism about the measurable benefits of the program, despite studies suggesting it could boost snowpack by up to 20%. The move also highlights tensions between Upper and Lower Basin states, with Arizona potentially losing leverage in water-sharing negotiations. Reduced snowpack could exacerbate water shortages in the region, affecting agriculture, urban water supplies, and reservoir levels.
