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 …

A guest post by David Rosenberg. David E. Rosenberg Utah State University | david.rosenberg@usu.edu | @WaterModeler The term buy-and-dry plays to the fears of farm and ranch communities. Wealthy urban water providers buy up water rights, dry out farms and ranches, encourage people to retire to Hawaii or other locales, and export the purchased water …

Preparing for climate change on the Colorado River is hard. But we will make it harder, and narrow the scope of our options for dealing with it, if we don’t incorporate realistic flow reduction scenarios in our planning efforts. That’s the thrust of an editorial Brad Udall and I have in this week’s issue of …

The latest US Bureau of Reclamation “24-month study” – the monthly update to projected reservoir storage on the Colorado River – shows the bottom dropping out of Lake Powell inflows after a starkly dry April. With inflows down a million acre feet from the April version of the study, the Bureau is now projecting total …
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 …

Ima give this a fancy sciency-sounding patina: I walked a transect today across the ribbon of green the Rio Grande provides through the heart of Albuquerque. I’m trying to think through what I have come to understand as the fundamental choice we face as climate change depletes the river. We will have less green: Which …
tl;dr I’m stepping down as director of the UNM Water Resources Program at the end of summer semester to write another book. longer When I was happily toiling those many years as an inkstained wretch, I had secret fantasies of leaving newspaper work to spend my waning years on the campus of the University of …

It’s been more than a year since I’ve been able to update my Lake Mead bathtub ring pictures, but perhaps this graph, updated with the new Bureau of Reclamation projects into fall 2022, will help us visualize what we’re up against.
By Eric Kuhn The release of last week’s Bureau of Reclamation 24-month study felt like very bad news for the Colorado River (See Tony Davis for details.). But a careful reading of the numbers, and an understanding of the process through which they are developed, suggests things are likely even worse than the top-line numbers …
