AP is reporting this evening that a state judge in California has thrown out the 2003 deal by which California agreed to stop using so damn much Colorado River water: A California judge has tentatively invalidated a landmark pact to curtail the state’s overuse of water and allow other Western states to claim their fair …

In Dead Pool, James Powell sketches out an apocalyptic scenario facing the hydraulic society we’ve built in the West on Colorado River water. (It’s a great read. If you’re interested in western water, you daren’t miss it.) After building up the history, science, politics and policy that have developed over the last century, Powell lays …

From yesterday’s newspaper, a slightly sheepish ode to my fascination with really, really big water engineering projects (sub/ad req.): From the time I first toured Hoover Dam as a kid — “enough concrete to pave a strip 16 feet wide and 8 inches thick from San Francisco to New York,” as the Bureau of Reclamation …

The first review of my book is in, and it’s a good one (albeit less than 140 characters long): great for us non-youths too. Highly recommended. The Tree Rings’ Tale, available now.
If we can all avert our eyes for a moment from the CRU emails, the inexorable momentum of climate science hurtles down the track with a new paper in today’s Science using paleo records to suggest (among many interesting things) that a warming world is, for the southwestern US, a drier world. Mike Mann and …

It’s early days yet in terms of a forecast for 2009-10 flow on the Colorado River. Because it depends on the amount of snow that falls on the Colorado Basin’s mountains, there is great uncertainty this early in the year. But the map below can give us some hint about the probabilities: What you can …
When I was a little kid, I thought John Wesley Powell was the coolest, the one-armed adventurer daring the unknown as he ran the rapids of the Grand Canyon – the “Great Unknown” – for the first time. Standing on the Grand Canyon’s south rim, I would stare down at those little glimpses you get …
Given the sturm und drang over Lake Mead’s dropping levels and their implications for the water future of Las Vegas, the preliminary numbers in the U.S. Bureau of Reclamation’s 2010 Annual Operating Plan are worthy of note. The latest posted version of the plan is marked “final draft”, but I’m told it’s essentially complete, and …

It’s worth noting that the current conversation about Atlanta’s water future has not arisen because of questions about sustainability of water supplies for the various users in Apalachicola-Chattahoochee-Flint River Basin. It’s instead the result of a legal issue: Atlanta’s primary source of supply, Lake Lanier, was never authorized by Congress to serve as a water …

Pasadena, CA, blogger Wayne Lusvardi, who sometimes writes about that city’s water problems, had a post recently suggesting that global warming might lead to increased flows in the Colorado River. This would, of course, be excellent news for Pasadena and others who use Colorado River water (thought it does conflict with some of the literature …
