BLYTHE, CALIF. – It’s not quite the way I remember it. I suppose it never is. I’m on a reporting trip. I had some meetings in Phoenix today, then made a freeway dash out to the Colorado River for a few days of journalism-by-wandering-around. I ended up this evening near sundown in Blythe, Calif., dumped …
On the road, I made it to greater Phoenix this evening in time to catch the five o’clock show at Fountain Hills, a suburban enclave on the northeast edge of the metro area.
While the current snowpack numbers look lousy for Colorado River Basin runoff, a glimmer of hope for a late-season uptick in the latest Climate Prediction Center seasonal outlook. Green means “odd tipped toward wet”: I prefer to ignore, then the cognitive dissonance caused by this:
The new paper by Ben Cook and colleagues clarifying our understanding the risk of megadrought in the southwestern United States has rightly gotten a lot of attention. Combining paleo records and modeling of a changing climate under rising greenhouse gas scenarios, Cook and his colleagues have created some scary reading: [F]uture drought risk will likely …

Last year, I began experimenting with a sort-of-weekly (except when it’s not) emailed water newsletter. I’ve got a few reasons for doing it: Some people read blogs, some people do twitter, some like email, I’m trying to reach folks where they’re most comfortable. Marketing! I’m going to have a book to sell soon, and a …
January was bad for snowpack and therefore spring runoff in the Colorado and Rio Grande basins. February has been worse. But we don’t use water at the basin scale, we use it one irrigation district and city at the time. Here I will attempt to sum up the current snowpack and water supply situation and …

Getting mentally packed for a reporting trip later this month to southern Nevada, I ran across this delightful bit of business, from (I think) 1904: William R. Clark, a U.S. Senator from Montana, had bought an old ranch in the valley in 1902, land that became the staging area for the Union Pacific’s construction of …

The Colorado Basin’s two primary reservoirs lost, on paper, a million acre feet of water because of January’s dry snowpack, according to the latest numbers from the U.S. Bureau of Reclamation. That’s the difference between what we expected to end the current water year with based on the January forecast, versus what the forecast looks …

We have a mismatch between 20th century plumbing and a 21st century climate. USGS hydrologist Paul Milly and colleagues in 2008 threw down a marker in a Science paper arguing that human interventions (intentional and not) have rendered a basic premise of human water operations invalid. The premise is “stationarity”, the idea that with data …

Let’s talk about “polycentric governance” and the problem of regional water institutions, shall we? Because here in New Mexico, we seem to have this a bit messed up, and my book research is leading me into some compare-and-contrast exercises that might be useful in thinking our dilemma through in more detail. Dennis Domrzalski, writing in …
