We’re entering the end-of-year water accounting phase of the Rio Grande hydrograph in central New Mexico, with big flows coming out of the Rio Chama, the largest tributary in this stretch of our “big” river. As I’ve written before, relatively higher December flows are a weird artifact of water management rules, which do accounting on …

Daniel Rothberg yesterday published a very helpful Q and A with John Entsminger of the Southern Nevada Water Authority that gets to the heart of one of the really important discussions now underway in the Colorado River Basin: Rothberg: You mentioned not that long ago, testifying in Congress, that “the river community is far from …
FYI all, I’ve deleted the post with the soil moisture map. It was dated 2020, not this year. That’s what get for enthusiastically curling up in my comfy chair with my new laptop and blogging while still on first cup of coffee.
One of the conceptual riddles Bob Berrens and I are working through in the new book we’re pursuing on New Mexico’s Middle Rio Grande, and the work surrounding it, is the ecosystem goods and services across our valley floor provided by the Middle Rio Grande Conservancy District’s web of irrigation ditches. Where once we had …

I’ve been spending an inordinate amount of time the last few weeks pointing and clicking on the new OpenET project’s “data explorer”. Using satellite data and magical algorithms, OpenET allows me to look at an arbitrary bit of land and retrieve an estimate of the amount of “evapotranspiration” – essentially outdoor water use – for …

With the ink barely dry on the ill-named Colorado River “Drought Contingency Plan”, the Lower Basin states (Nevada, Arizona, and California) are already cooking up a Plan C for even deeper reductions. Joanna Allhands at the Arizona Republic has a nice look at what we know about the details: Arizona, California and Nevada are moving …

Peña Blanca, NM – The Cochiti Main, winding through the village of Peña Blanca, was still flowing Saturday morning with some of the last of this year’s irrigation water destined for farms to the south. I’m a bit jammed up in my effort to return to writing (see below for the “some personal news” portion …
Heather Sackett did a good story this week on new data Brad Udall has been sharing that geographically parses the declines in streamflow across the Colorado River Basin. For folks like us down here in New Mexico, dependent on the San Juan as a critical source of supply, the news is not good: This month, …
