It is telling that I got excited when I noticed inflow into New Mexico’s Middle Rio Grande Valley approaching “normal”, which I now define as the median of 21st century flow. Our climate-altered world, y’all. A note on the evolution of the graph: I’ve added the “max” and “min” lines back. I dropped them because …
Inspired by Jack Schmidt’s monthly “how much water is in Colorado River storage” posts (see here for last month’s), I’ve been playing with a similar tool to help me think about the status of our reservoirs on the Rio Grande system here in New Mexico. The graph above helps me with two important intuitions about …

A guest post from my Utton Center colleague and Colorado River research collaborator Rin Tara, staff attorney and water policy and governance analyst at the Utton Center, University of New Mexico School of Law. By Rin Tara Over the last year, I had the joy of working with John on a law review article …
The U.S. Supreme Court will hear oral arguments tomorrow (Wed. March 20, 2024) about the fate of ongoing litigation between Texas and New Mexico about how to share the waters of the Rio Grande. The two states (Colorado is technically a party two, but this is really Texas v. New Mexico) have what they think …

Six days later, Lázaro Quintana, the mayordomo, opened the headgate and sent the first water of the new season down the five-mile long ditch, empty since the November before. When the brown water finally arrived four hours later at the bridge, the tip of its foamy tongue was bearing along a small plum branch that …

It’s hard to tell this morning what yesterday’s howling dry winds did to our snowpack. It’s the sort of thing that can cause sublimation, which means the loss of snow straight to atmospheric drying without ever having a chance to melt and make it to the rivers. It looks like some snow may have fallen …

The Middle Rio Grande Conservancy District’s crews will usher the first water into the ditches of New Mexico’s middle valley Feb. 26, district Water Distribution Division Manager Matt Martinez told the district’s board at yesterday afternoon’s meeting. The early water doesn’t go to irrigators right away. It’s needed to “charge” the system, wetting earthen ditches …
Folks in Colorado’s San Luis Valley are engaged in a bold experiment in western water management – charging farmers for the water they use. Jerd Smith explains: A new rule approved by the area’s largest irrigation district, known as Subdistrict 1, and the Alamosa-based Rio Grande Water Conservation District, sets fees charged to pump water …

I’ve been updating the crufty old code I use to generate graphs to help me (and colleagues) think about river flows. This one’s a little busy, so maybe for specific nerd colleagues’ use, and not general consumption? It’s based on a request from a friend who uses these, and asked for a visualization of the …

This Rio Grande crossing, just south of Belen, 30-plus miles downstream from Albuquerque, has changed dramatically since Jack Delano took the picture above in spring 1943. The Bosque I’ve stared at Delano’s picture often, because of the story it tells – a broad open river valley. It’s nothing like that today. I pieced together …
