U.S. Orders Major Colorado River Cuts For California, Nevada, Arizona
On Friday, August 21, 2026, the Bureau of Reclamation announced two years of cuts that reduce Colorado River deliveries by 1.25 million acre-feet annually to California, Nevada and Arizona.[1]
Arizona will shoulder the largest share of the reductions, while Colorado, Utah, Wyoming and New Mexico face no new cuts under the plan.[1] Mexico will cut its Colorado River use by 250,000 acre-feet per year under a bilateral treaty.[1]
Lake Mead and Lake Powell recently fell to their lowest levels since their initial filling. A projected further 33-foot drop at Lake Powell could stop hydropower generation through Glen Canyon Dam. Existing Colorado River operating rules expire in October 2026, and the seven basin states have not reached a long-term allocation agreement.
