With flows in the Rio Grande dropping rapidly, Albuquerque will stop diverting drinking water from the river Friday, switching to its groundwater wells for municipal supply. This is the second year in a row that dry conditions have so depleted the river’s flow that the Albuquerque Bernalillo County Water Utility Authority had to shut down …

I got an email this morning from a friend watching as the bottom begins to drop out of the Rio Grande’s flow at a place called Otowi, north of Albuquerque. When Otowi drops, the river here in Albuquerque soon follows – one of those upstream/downstream things. It’s been a weird year on our river – …

The 1928 report they call “Burkholder’s Bible” – more formally “A Plan For Flood Control, Drainage and Irrigation of the Middle Rio Grande Conservancy Project” – must be treated as one of modern Albuquerque’s founding texts. Like any such text, it rewards careful reading. Also in the manner of such texts, the more you read …

Following what NRCS forecaster Angus Goodbody describes as “an exceptionally dry April”, our anticipated Rio Grande runoff into New Mexico’s Middle Rio Grande valley (meaning the flow at the Otowi gauge) is down 100,000 acre feet from a month ago. That’s about 44 percent of the 30-year mean. Importantly, April was really our last chance …

I mostly hate log scale in graphs I use for broad communication purposes. It’s just not intuitive. But I’ve made the switch for this year’s Rio Grande, because the flows are so low that we need the log scale, because at really low flows small changes become big, if that makes any sense. The difference …

My friend and colleague Becky Bixby (UNM biologist, associate director of the UNM Water Resources Program) gave a great talk recently about her work on the diatoms – little light-eating algae – on the margins of our river. (first 10-ish minutes is Becky)
An email exchange with a friend who helps manage New Mexico’s water led to the graph above, my first stab at a visualization to try to show the accumulation of two bad years’ flow on the Rio Grande. Not quite sure this does all the work yet that I need of it, but perhaps worth …

No sooner did my spring break begin a week ago (quite literally within a couple of hours of the end of my last class before break) than I got sick. This has led to much laying around, and resting, which I think was the point? I’m finally on the mend, and a friend got me …

We stopped on Saturday’s bike ride for one of my favorite views of the Rio Grande, looking north from the Gail Ryba Bridge (the bike bridge that parallels Interstate 40). The Rio Grande looks great right now, but looks can be deceiving. This time of year there’s always “base flow” – the basic winter flow …
