Department of the Interior Imposes Deep Colorado River Water Cuts for California, Arizona, and Nevada

LAS VEGAS, NV — The U.S. Department of the Interior and the Bureau of Reclamation announced mandatory water allocation reductions Friday across the Lower Colorado River Basin, impacting agricultural irrigation and municipal water supplies in California, Arizona, and Nevada for 2027.

Hydrological Projections and Allocation Reductions

The 24-Month Study released by federal hydrologists confirmed that storage levels at Lake Mead and Lake Powell will remain in Tier 2 shortage conditions due to persistent drought and reduced snowpack runoff in the Upper Basin.

Under the revised schedule, Arizona will absorb a 21 percent reduction in its Central Arizona Project delivery, Nevada will see an 8 percent adjustment, and California will implement conservation reductions totaling over 400,000 acre-feet across agricultural irrigation districts in the Imperial Valley.

Regional Adaptation and Federal Mitigation Funds

Federal officials announced $250 million in supplemental Inflation Reduction Act grants for municipal water recycling projects and agricultural canal lining to offset local disruptions. State water authorities in Phoenix and Los Angeles reiterated that proactive water bank reserves will protect residential drinking water supplies throughout the adjustment period.
