Colorado River Negotiations Turn on Who Bears the Shortfall
Colorado River demand has exceeded natural supply for roughly 26 years, drawing down Lakes Mead and Powell as warming reduces runoff even in years of average precipitation, according to Anne Castle and Arizona water director Tom Buschatzke. With current operating rules expiring and no seven-state agreement in place, the basin must decide how to bring use closer to supply—and the article argues that decision cannot be treated as an acre-foot accounting exercise alone. It also bears on tribal access to water rights that have not been developed and on how communities can withstand the economic transition where agricultural use is permanently retired.
