Severe drought and mandatory water cuts are pitting communities against each other in Arizona:

As the climate crisis intensifies, battle lines are beginning to form over water. In Arizona -- amid a decades-long megadrought -- some communities are facing the very real possibility of losing access to the precious water that remains.

Outside the city limits of Scottsdale, where the asphalt ends and the dirt road begins, is the Rio Verde Foothills community. Hundreds of homes here get water trucked in from Scottsdale, but those deliveries will end on January 1, 2023.

That's because last summer, for the first time ever, drought conditions forced the federal government to declare a tier 1 water shortage in the Colorado River, reducing how much Arizona can use.

[...] "We are what I call the 'sacrificial lamb' for the bigger areas," Irwin told CNN. "In my opinion, look somewhere else -- we need to be able to sustain ourselves."

The scarcity of water in the state is pitting small towns against fast-growing metropolitan communities.

[...] Arizona's population growth and extreme drought have increased demand for water in limited supply. Kathleen Ferris, a senior research fellow with the Kyl Center for Water Policy in Arizona, says water scarcity in the state has resulted in the "haves" and the "have nots," and likened the coming water battles to the days of the Wild West. "Once you have your water rights, you defend it," Ferris said. "That's the way it works."

    From https://en.wikipedia.org/wiki/Colorado_River_Compact [wikipedia.org]

    Specifically, the amount of water allocated was based on an expectation that the river's average flow was 16,400,000 acre-feet (20.2 km3) per year (641 m³/s). Subsequent tree ring studies, however, have concluded that the long-term average water flow of the Colorado is significantly less. Estimates have included 13,200,000 acre-feet (16.3 km3) per year (516 m³/s),[15] 13,500,000 acre-feet (16.7 km3) per year (528 m3/s),[16] and 14,300,000 acre-feet (17.6 km3) per year (559 m3/s).[17] Many analysts have concluded that when the compact was negotiated, the period used as the basis for "average" flow of the river (1905–1922) included periods of abnormally high precipitation,[18] and that the recent drought in the region is in fact a return to historically typical patterns.
