Shortage Impacts
Shortage Impacts
The Colorado River Basin continues to experience drought and the impacts of hotter and drier conditions. The Colorado River Basin is in a Tier 1 shortage for 2024. This represents a 512,000 acre-foot reduction to Arizona’s Colorado River water supply, constituting 30% of CAP’s normal supply, about 18% of Arizona’s Colorado River supply, and just under 8% of Arizona’s total water use. Nearly all the reductions within Arizona will be borne by Central Arizona Project (CAP) water users.
