The U.S. Bureau of Reclamation imposed an additional 80,000 acre-feet of cutbacks to Arizona from Colorado River deliveries in 2023, to 592,000 acre-feet — more than 20% of the state’s annual apportionment of 2.8 million acre-feet. Under a Tier 2 shortage declaration, Arizona will see cutbacks along with Nevada and Mexico. California, which has senior rights among the three Lower Basin states, does not face a mandatory cutback next year. One acre-foot, or about 326,000 gallons, is typically enough water for six to eight persons’ annual needs.
