Shortage Impacts

The Colorado River Basin continues to experience drought and the impacts of hotter and drier conditions. Based on the Jan. 1 projected level of Lake Mead at 1,065.85 feet above sea level, the U.S. Secretary of the Interior has declared the first-ever Tier 1 shortage for Colorado River operations in 2022. This Tier 1 shortage will result in a substantial cut to Arizona’s share of the Colorado River — about 30% of Central Arizona Project’s normal supply; nearly 18% of Arizona’s total Colorado River supply; and less than 8% of Arizona’s total water use. Nearly all the reductions within Arizona will be borne by Central Arizona Project (CAP) water users. In 2022, reductions will be determined by Arizona’s priority system – the result will be less available Colorado River water for central Arizona agricultural users.

A matter of priorities

To understand these impacts, see an “explainer” on the CAP Priority System.
