A new paper by Megan Miller and Manoochehr Shirzaei at Arizona State describing subsidence in the Phoenix area offers some interesting new data for thinking about the implications of groundwater management. Subsidence is bad, and groundwater pumping is what causes it. Having the ground surface drop is bad all around, cracking building foundations, messing up roads, and such. …

Pulling together some New Mexico water use numbers today for one of my University of New Mexico colleagues, I was reminded of a cool paper from a few years back by Peter H. Gleick and Meena Palaniappan of the Pacific Institute that contained this striking graph: It’s two times series – U.S. gross domestic product and …

I’ve got a piece over at Water Deeply on Arizona’s latest latest self-destructive Colorado River Basin outburst and the clash between state-by-state domestic politics and the realities of management at the Colorado River Basin scale.
“Regulatory arbitrage” is the business practice of shifting one’s operations to exploit differences in regulatory regimes. This often involves a geographical change, such as moving a factory to a place where environmental regulations are less stringent. That seems to be what’s going on in southeastern Arizona, where California nut farmers are moving into the San …

Importantly, he’s looking at it not just as a problem, but as an example of what the solution space can look like. The stuff from Kathryn Sorensen, Phoenix’s water …

In this morning’s Arizona Star, Tucson journalist Tony Davis asks, “Is California trying to take our water?” In journalism, there’s a joke known as “Betteridge’s Law“: “Any headline that ends in a question mark can be answered by the word no.” As Tony’s story strongly suggests, the notion making the rounds these days in some Arizona political …
Our big wet May looks to have all but eliminated the possibility of a Lower Colorado River Basin shortage in 2016, and it now looks like a better than 50-50 chance we won’t have one in 2017 either, according to the U.S. Bureau of Reclamation’s monthly outlook, published this afternoon (pdf). A shortage is triggered if …

Tony Davis asked Arizona officials if they had any actual evidence that California was trying to steal their water. Their official statement: “ADWR is not aware of any California efforts intended to take a portion of Arizona’s water supply directly. However, any changes to Colorado River operations could affect everyone who relies on the River. …
In the fall of 1934, Arizona Gov. Benjamin Moeur dispatched the Arizona National Guard to the banks of the Colorado River near its junction with the Bill Williams to try to block efforts to build what would eventually become Parker Dam. Their fear: that the Colorado River Aqueduct, which would tap into the new reservoir, …

As Lake Mead drops toward a Lower Colorado River Basin shortage declaration, a group of UC Santa Barbara students have done an excellent analysis (pdf of their summary results) that shows where the real vulnerabilities are. They conclude that Las Vegas and the municipal areas of Central Arizona are on solid ground. Arizona farmers won’t …
