A proposed Colorado River drought plan that will cost well over $100 million is just the beginning of what’s needed to protect the over-allocated river, says Bruce Babbitt, the former governor who rammed through Arizona’s last big water legislation nearly four decades ago. After Gov. Doug Ducey urged legislators to “do the heavy lifting” and pass the proposed drought-contingency plan for the Colorado, Babbitt said Monday that authorities will have to start discussing a much longer-term plan immediately after it’s approved.
