Writing in the latest Nature Geoscience, Reiner Grundmann of the University of Nottingham calls out a problem that I wish I’d understood years ago about our understanding of, and response to, climate change and the family of problems to which it is connected. (I hope that link works, let me know in the comments if it …
Climatic consequences of adopting drought tolerant vegetation over Los Angeles as a response to California drought, Vahmani and Ban-Weiss, GRL, July 2016 found that when you tear out lawns, it gets warmer during the day but that overnight cooling could more than balance things out: Transforming lawns to drought tolerant vegetation resulted in daytime warming of …

I wanna tell you the story of the time I met Sandra Postel in a dry riverbed in the deserts of Mexico. When I first started writing about water more than two decades ago, the work of the water scholar Postel was both informative and inspirational. As much as anything I came across, her work …

Laura Paskus writes: Almost 50 years ago, on June 14, 1967, four couples fired off a telegram from Las Cruces to Sen. Henry Jackson, a Democrat from Washington. Called “Scoop” by his pals, Jackson chaired the Senate committee looking at a bill to authorize the Central Arizona Project, a system of dams, canals and aqueducts …

I’m happy (nay enthusiastic!) to point out the way Lake Mead keeps dropping, but it’s worth nothing this as well: Colorado River water use in Arizona, Nevada, and California this year is currently forecast at 7.006 million acre feet (source: pdf), well below the three states’ nominal legal entitlement of 7.5 million acre feet. The …
On what is apparently Colorado River Day (who decides such things?) I made a little pilgrimage this afternoon to see the Shoshone hydro plant, just up river from the little town of Glenwood Springs on Colorado’s west slope. Shoshone has a unique place in the water management of the Colorado River Basin because of western …

Eric Kuhn, General Manager of the Colorado River District, took me for a walk along his river yesterday evening, pointing out the muddy flow of the Colorado, coming in from the left, at its confluence with the Roaring Fork River – the clear water coming in under the railroad bridge. This is on the state …

Reichenbach Falls: Frenchman Pierre Rolland and Swiss Sebastien Reichenbach were also among those who crashed on slippery roads.
Remarkable piece by UNM water professor emeritus Basia Irland: I flood. That is what I — and all my cousins — do from time to time. It is part of our rhythm. In their hubris, humans build cities and towns right on our banks, then get upset with us when our waters rise and destroy …
