When we think today about Arizona’s water problems, we imagine large lawns in sprawling suburbs in and around Phoenix, golf courses, and “misters”—those devices that fritter away water into the hot desert air to cool the customers eating at outdoor restaurants in the Valley of the Sun. Me, in Water is For Fighting Over Lissa …
Forecast flow through the Azotea Tunnel, which provides New Mexico’s San Juan-Chama Project supplies of Colorado River water to Albuquerque and central New Mexico, are forecast to be 152,000 acre feet for the 2016-17 water year, the highest flows of the 21st century.
Audubon has an excellent new report on risks to birds, and all that go with them, along the rivers and arid landscape lakes across western North America. Lots there, but I think this bit is especially important: Without reform, today’s water management framework could lead to severe water shortages to large numbers of people and …
One suggested short term tool to deal with the shrinking Salton Sea is to continue putting in more water. New research suggests that, for fish and birds, it won’t help. “Mitigation water” is jargon for extra water currently diverted to the Salton Sea to make up for reduced agricultural runoff as efficiency improvements. (It’s hairy …

Speaking earlier this month at the University of Colorado’s Martz Conference, Brad Udall offered what amounted to a bibliography, both helpful and deeply unnerving, of recent scientific literature documenting what we have learned in recent years about climate change and water in the Western United States, and what it tells us about our future prospects. …

One of the main focuses of the class I help teach in the fall, “Contemporary Issues in Water Management“, is the nature and function of “coupled human and natural systems”. (In fact, might say it’s the main focus of the entire UNM Water Resources Program, come to think of it.) One of the biggest difficulties …
Chuck Cullom, the Central Arizona Project’s Colorado River Programs Manager, asked a great question during my lunch talk last week at the Universities Council on Water Resources annual meeting. It was a panel with me and Bill and Rosemarie Alley, who’ve written a new book on groundwater that you should click on this link and …
The Bureau of Reclamation’s June Colorado River forecast projects Lake Mead ending 2018 at elevation 1,076.5 feet above sea level, three feet higher than the Bureau’s January projection of 1,073.5. If the forecast holds, that’s enough of an increase in Mead storage, thanks to a larger-than average snowpack in the Rockies, to avoid a shortage …

Eric Kuhn points out that the Colorado River in Glenwood Canyon on Colorado’s West Slope, and its major tributary here the Roaring Fork, peaked last Friday, right around the time I was up there gawking at all the water: Flows on the Colorado River at Dotsero and the Roaring Fork River at Glenwood Springs …
The Phoenix City Council today agreed to pay the Gila River Indian Communities $2 million as part of a deal to leave 40,000 acre feet of the Indian Communities’ Colorado River water in Lake Mead this year. The state of Arizona, the federal government, and the Walton Family Foundation also are contributing. From the city …
