ARIZONA - STRONGER TOGETHER

The Colorado River Basin continues to experience drought exacerbated by the impacts of climate change. For 2022, the U.S. Secretary of the Interior declared the first-ever Tier 1 shortage for Colorado River operations. This Tier 1 shortage has resulted 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 have been taken by Central Arizona Project (CAP) water users. These reductions were determined by the CAP priority system – the result being less available Colorado River water for central Arizona agricultural users. Current projections point to Tier 2 shortage operations in 2023, which will equate to reductions in the supplies available to municipal/industrial and tribal water users.
