Lower Basin States Brace for Major Colorado River Water Cuts

Under the federal framework, the three Lower Basin states could face water share reductions of up to 3 million acre-feet annually through 2036. This volume is roughly equivalent to the combined annual amount currently received by Nevada and Arizona. The Colorado River provides vital water resources to 40 million people across seven U.S. states, multiple Native American tribes, and Mexico. The proposed allocation cuts are scheduled to take effect next year, with provisions to review and adjust figures every two years based on hydrological conditions across the entire basin. Elected officials from the affected states raised immediate objections. Arizona Governor Katie Hobbs stated that while upcoming water cuts will be difficult, she hopes federal authorities will instead implement a two-year transitional plan crafted jointly by the Lower Basin states, which calls for less drastic reductions through 2028.

Meanwhile, Arizona Senate President Warren Petersen and President Pro Tem T.J.
