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 …

From my conversation last week with Drew Kann at CNN: To Fleck, all of this signals that the reduced flows in recent years are likely not an aberration, but rather a glimpse of the challenges posed by a hotter, drier climate. “We’re now seeing the model for what the future of Colorado River Basin water …
I’m choosing my words carefully here. The “likely” in this blog’s post’s title means “based on my analysis of the Bureau of Reclamation’s current ‘most probable forecast’ Colorado River water supply model runs.” The Bureau’s current “most probable” modeling suggests that in both 2022 and 2023, the annual release from Lake Powell will only be …

Cleaning out some old files this morning, I ran across this great quote from Pat Mulroy some years back from a talk about the problems of the Sacramento-San Joaquin Delta. Via’s Maven’s Notebook: We are very, very good at saying no. We are very, very good at blocking. Anybody can stop anything. What we can’t …

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)
