Phoenix Faces Colorado River Water Cuts Amid State Dispute

New restrictions on water use from the Colorado River, anticipated later this year, are poised to significantly impact seven states, with the rapidly growing suburbs of Phoenix facing a particularly challenging situation. The federal government's forthcoming plan aims to resolve a long-standing dispute among these states by updating the century-old legal framework governing water allocation in the Southwest. This framework operates on a "first-come, first-served" priority system for entities holding rights to the river's water, including states, Native American tribes, and municipalities in Mexico. Arizona's water rights are designated as "junior" compared to those of states like Colorado and Nevada, placing it at a disadvantage in the allocation process. Arizona leaders have voiced strong opposition to the proposed plans, which, according to reports, could mandate up to a 20% reduction in water usage for Arizona and other "lower basin" states. These reductions are necessitated by the dwindling water levels in Lake Powell and Lake Mead, critical reservoirs for the region. Phoenix Mayor Kate Gallego stated that while Phoenix has prepared for such a scenario and is capable of reducing its Colorado River water consumption, it is inequitable to impose a disproportionately large share of the burden on Arizona. In contrast, "upper basin" states, which primarily draw water from the Colorado River's headwaters and tributaries, may not experience such stringent restrictions. Tom Buschatzke, director of Arizona's Department of Water Resources, indicated in June that cities within Arizona have been planning for potential water reductions for years and will have some flexibility in managing their water use. However, he acknowledged that cities will inevitably need to decrease their water consumption. Buschatzke does not foresee widespread restrictions on the use of tap water but highlighted the possibility of outdoor water use limitations. The state is also intensifying its scrutiny of water-intensive developments, such as data centers. He warned that "pretty serious action" is required, which will involve "additional reductions" as a certain measure. The economic implications of water scarcity on housing markets have been studied by Benji Edelstein, an assistant professor of economics at Loyola University Chicago, who has examined how such scarcity affects home prices and development patterns in water-stressed regions.
