Nevada journalist George Knapp has a wacky suggestion for Pat Mulroy on her way out the door at the Southern Nevada Water Authority: [I]t is still possible for Mulroy to make a grand, parting gesture by starting the ball rolling on a plan to drain Lake Powell…. This’d make an excellent final chapter for my …

While much of the attention on the “ridiculously resilient ridge” has, rightly, focused on its effect on California’s drought, out here in the intermountain west we’ve been suffering too. Albuquerque is on the brink of its longest precip-free winter stretch on record (these records go back to 1920). And for the Colorado Basin? What had …

I’m on the hunt for the origins of the phrase “practicably irrigable”. If anyone has any insights, please jump in on the comments. Here’s what I know: The concept is central to water law in the western United States. The first reference I’m able to find in the U.S. legal canon is in the 1960 …
California’s remarkable, looming drought conditions are a test, and via OtPR we’re seeing some clues as to who will pass: Southern California prepared for this and has a sufficient buffer that it doesn’t need to ration this year. And how did Southern California prepare? In part by being audacious enough and rich enough, but also …
Back in the 1980s, a researcher named Lawrence Hamilton (gated JSTOR paper here) studied water use and conservation behavior among the residents of 431 homes in Concord, New Hampshire. Concord’s a classic case – a slow, steady population increase putting pressure on supply that’s manageable during wet times but that became a problem in 1980, …

In his book Border Oasis, Evan Ward tells the story of the transborder conflict between the United States and Mexico over salinity in the Colorado River. “Unfortunately,” Ward writes, “sometimes when one region solves its salinity problems, it creates new salinity problems for people downriver.” The conflict Ward describes began in 1961 when farmers on …
I was reminded at a talk last night that farmers in the Elephant Butte Irrigation District in southern New Mexico got less than 10 percent of a full irrigation allotment last year. I say that by way of a preface to noting Juliet McKenna’s observation that there’s a 50-50 chance of a formal shortage declaration in …
I suppose it’s a sign of the times on the Colorado River that a January forecast of 95 percent of average flow into Lake Powell counts as good news. Since green on the Colorado Basin River Forecast Center map runs from 90 to 110 percent, we get green. It’s only a little bit below average! …

From the U.S. Bureau of Labor Statistics: Yuma, Ariz., and El Centro, Calif., had the highest unemployment rates in October, 31.9 percent and 25.2 percent, respectively. These folks are getting a lot of Colorado River water. There’s seasonality to the resulting ag work economies, but really, this is a graph of economic suckage:
According to the U.S. Bureau of Reclamation’s new Consumptive Uses and Losses Report (pdf), consumptive use of Colorado River water in the states of the upper basin (Colorado, New Mexico, Utah, Wyoming and a sliver of Arizona) reached 4.281 million acre feet in 2011, the highest on record. The previous high was 4.245 million acre …
