ARIZONA - STRONGER TOGETHER
The Colorado River Basin continues to experience drought exacerbated by the impacts of climate change. The Lower Basin has been in a Tier 1 shortage in 2022 and will be in a Tier 2a shortage for 2023. The 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.
