I’ve written before about the possibility that we could view Australia’s struggles with long term drought, especially in the Murray-Darling Basin, as a model for how to deal with things here in the arid southwest. This version of the model is perhaps not quite so hopeful. From Australian Broadcasting: A guide for water allocations in …
“Water year” 2010 ends next week, making this a good time to take stock of our historic position on the Colorado River. And by a couple of different measures, things are truly historic: The latest forecast (and right now forecasting amounts to tiny fractions of in inch) puts Lake Mead’s surface elevation at 1084.14 feet …

In a debate between candidates for Colorado Congressional District 3 (the western part of the state, including the west slope and Colorado river), the two candidates are reported to have shown clear agreement on an important point: Both pledged heartily to fight all efforts to reopen the Colorado River Compact. Also, all efforts to switch …

With La Niña rapidly strengthening, it is reasonable to ask what can be said about the resulting effect on flows in the Colorado River. The short answer: not much. It is reasonable to guess otherwise, because so much of the southwest depends on the Colorado for its water supply, and because La Niña is so …
Lissa found a treasure for me at Sam Weller’s in Salt Lake City – the March 1956 issue of Arizona Highways: Among the gems within is Ak Akvik’s Servant of the People (tribute to Hoover Dam). An excerpt: Below, stilled forever the red rage of the angry river. Below, in blue serenity, as docile as …
Speaking at a symposium in Las Vegas in April, former Bureau of Reclamation Commissioner Bob Johnson made a critical point about the differences between water problems on the Colorado River and the current struggles in the southeast over the Apalachicola-Chattahoochee-Flint and Alabama-Coosa-Tallapoosa river basins. The ACT-ACF fights made the Economist this week, in an article …
I love this picture of what I can only assume are three rascals defying their mothers and swimming in the New River, in the Imperial Valley of Southern California in 1905. The New River, in the incarnation seen here, was formed when the Colorado River ate through a poorly built intake structure and chewed up …
Without pack animals and before fueled machinery, the ability of a human to carry food placed a fundamental constraint on economic integration across large distances. Over any significant distances, a human would have to eat all the food they could carry, leaving none left for trade. Trade of small, high value items could go on …
In an interview over at Grist, Brad Udall reminds us that, as we think about the effect of climate change on the West, it’s not just the thorny question of whether precipitation rises or falls that matters. Despite the uncertainties surrounding that question, as temperatures rise (a projection about which there is considerably less uncertainty), …
One of the central struggles in moving water out of the Colorado River a century ago was the silt. Moving water moves a lot of it, and when you slow the water down, the silt drops out. It was siltation that kept clogging Charles Rockwood’s Imperial Valley diversions, where he was taking water from the …
