On October 16, 2026, the states of Arizona and Nevada filed a joint lawsuit to block proposed federal reductions in Colorado River water deliveries.
The states contend that the cuts could dramatically lower water supplies for Phoenix, Tucson, farms and businesses throughout the region.
The legal action follows a federal plan to lower Colorado River allocations.
