Great new stuff from the Colorado River Wilburys – Jack Schmidt, Anne Castle, Eric Kuhn, Kathryn Sorensen, and Rin Tara*: Reductions in Lower Basin water use during the last four years, including forecast use in 2026, are similar to the initial targets for Lower Basin shortages described in the Final Environmental Impact Statement for Post-2026 …

At 2 p.m. Monday (Aug 31, 2026) the Albuquerque Bernalillo County Water Utility Authority, along with the Middle Rio Grande Conservancy District and Audubon Southwest, began releasing a pulse of water from Abiquiu Reservoir on the Rio Chama in Northern New Mexico as an experiment – what might a several day pulse of water do …
Of possible relevance to the current bosque dieback in New Mexico’s Middle Rio Grande? From PNAS: Predicting forest resilience requires knowing whether trees can physiologically acclimate to drought. Drawing on global in-situ field experiments, we find a pervasive lack of functional adjustment in forest trees. Trees maintain stable hydraulic and photosynthetic capacities, enabling maximum carbon …

It was 96F (35.5C) when I rode my bike home after class at 6:15 p.m. last night. “3.91 standard deviations above the long term record” is not terribly intuitive to me, the graphs above helped me visualize how extraordinarily unusual 2026 has been in Albuquerque. By all three normal measures – daily maximum, mean, …

I spent an unhappy evening yesterday staring at data, trying to make sense of the inevitability of change. I slept poorly. The Rio Grande through Albuquerque is dry, the Colorado River’s reservoirs are rapidly emptying and, unable to come to grips with this reality we have thrown up our hands and tossed the future of …
A guest post from longtime friend of Inkstain (and friend of the Colorado River) Karl Flessa. By Karl Flessa In the classic Monty Python sketch, a customer returns to the pet shop where, just 30 minutes ago, he purchased a parrot. He complains that the parrot is dead. The shopkeeper tries to convince the customer …

My Rio Grande thinking is almost entirely about the bits in New Mexico, but this, happening now at Big Bend, on the US-Mexico border, is worthy of note: Bulldozers have begun plowing up ground at the mouth of Big Bend national park’s famed Santa Elena Canyon as part of the Trump administration’s multibillion-dollar “smart wall” …
Albuquerque’s bosque has been suffering a rapid dieback, as shallow aquifers drop away from the roots of the community’s beloved cottonwood gallery forest. This is uncharted territory for our modern bosque, which grew into its present state after Bureau of Reclamation channeling in the 1950s created the modern river corridor, and flood control and water …

By Jack Schmidt and John Fleck John C. Page, Commissioner of Reclamation, reported to Secretary of the Interior Harold L. Ickes, in announcing the growth of Lake Mead, that the indications are enough water will be caught and stored by Boulder Dam this spring to put the operations of the Boulder Dam plant on a …
