The alley behind Aldo Leopold’s house
There’s an alley off Albuquerque’s Central Avenue, old Route 66, between the Southwest Capital Bank and St. John’s Thrift Store. You can’t go down the alley on Google Street View. Google Street View mostly doesn’t go down alleys. Alleys mostly don’t have names. You have to go there for yourself. Down past the “Drug Free …
Tools for better environmental adaptation as we manage the Colorado River
I put up a slide for my University of New Mexico water resources graduate students during class yesterday afternoon with two pictures – the emerging canyons at the upper end of Lake Powell, and a smallmouth bass.

Jack’s Graph is Better Than Mine
This version of the Colorado River graph, courtesy of Jack Schmidt, more clearly illustrates the narrative of the talk I’m giving later this week: Early 20th century pluvial, when we built the institutions Mid-century baseline, when we built all the dams and farms and cities Millennium drought, when we emptied the reservoirs

The persistent decrease in runoff is severely challenging the quest to rebuild reservoir storage. Summary Reservoir storage in the Colorado River basin is now …

Federal Judge Cites Upper Colorado River Basin’s Compact Call Risk
A federal judge this week criticized the federal government for failing to consider the risk of a Colorado River Compact call in its environmental review of the planning for Denver Water’s expansion of Gross Reservoir in Boulder County.

Assigned Water on the Colorado River: Arizona Department of Water Resources response
The Arizona Department of Water Resources has published a thoughtful and also delightfully testy response to Enduring Solutions on the Colorado River, the white paper Kathryn Sorensen et al. (I’m one of the et alias) published in August. First a reminder of our core premise: As we work to reduce water use on the post-2026 …
Rubber Soul, the path to elevation 1,040, and the game of chicken on the Colorado River
Two years ago, when the level of Lake Mead was hovering near elevation 1,040, my artist wife Lissa Heineman and I drove out over UNM’s fall break to see it for ourselves. Out beyond the old Boulder Harbor, we walked a half mile across mud flats to get to the water. I could look out …
