Over the past five weeks, we have described the wide range of water resources available to meet Arizona’s current and future needs. These resources include groundwater, in-state surface water, Colorado River water, long-term storage credits, and reclaimed water. We also discussed the latest developments on groundwater availability in the Phoenix Active Management Area. As these […]
On June 1, 2023, Arizona Governor Katie Hobbs revealed the results of a new groundwater model prepared by the Arizona Department of Water Resources (“ADWR”) that predicts the future availability of groundwater for pumping throughout most of the Phoenix Active Management Area (the “Phoenix AMA”) over the 100-year period mandated by ADWR’s Assured Water Supply […]
It seems that not a day goes by without another news story bringing Arizona to the forefront of a national dialogue about water security in a time of drought, changing climate, and growing population. This article is Part 6 of Snell & Wilmer’s series providing context for that dialogue as it applies to Arizona’s diverse […]
This article is Part 5 of Snell & Wilmer’s series on Arizona’s water supply and legal framework.

This article is Part 3 of a series providing information about the resilience of Arizona’s water supplies during a time in which the news is dominated by stories about drought and scarcity. As we noted in Part 1, Arizona has a very diverse water portfolio to draw on, including Colorado River water, in-state surface water, […]
While the local and national press inundate us with articles about the dire nature of Arizona’s water supplies and questions about why people are even allowed to live in a desert, careful planning by water leaders over decades has created resilient responses to these challenges that are unmatched in the Southwest and perhaps the nation.
