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.

Federal officials are expected to project next year's water shortage on Aug. 15. Arizona doesn't expect to lose more until at least 2027.
