Arizona, Nevada and Mexico will again get less Colorado River water in 2026

Arizona, Nevada and Mexico will again live with less water from the Colorado River as drought lingers in the West, federal officials announced Friday.

The Colorado River is a critical lifeline to seven U.S. states, 30 Native American tribes, and two Mexican states. The cuts are based on projections for levels at federal reservoirs — chief among them Lake Powell and Lake Mead — released every August by the U.S. Bureau of Reclamation.

Arizona will again go without 18% of its total Colorado River allocation, while Mexico loses 5%. The reduction for Nevada — which receives far less water than Arizona, California or Mexico — will stay at 7%. California won’t face any cuts because it has senior water rights and is the last to lose in times of shortage.
