To be clear: I think the Bureau of Reclamation’s announcement today that it is curtailing releases from Lake Powell in 2014 is a big deal. But one of the members of my brain trust (journalism is a mashup – I just repackage the ideas of people much smarter than myself) points out that there’s an …

Via the Albuquerque Journal: BOULDER – With the Colorado River Basin gripped by extreme drought, federal water managers Friday announced historic water conservation measures. Supplies in New Mexico, one of seven states that depend on the river’s water, will be untouched by the moves. But experts said the move is a warning that demand is …

The Bureau of Reclamation is going to tell us Friday that there’s not very much water in Lake Powell, and that as a result releases from Powell will be curtailed in the coming year, which sets off a cascading set of effects downstream. I took a crack at explaining this here, but Brett Walton has …
From Jay Lund, a comment on my post last week about low flows into that is worth elevating: Perhaps a bigger issue is that average unimpaired flow appears to be < 11 maf, but total allocations are more than 16 maf/year (1.5 maf/yr for Mexico and 7.5 maf each for the upper-basin and lower-basin states). …

Here’s a striking graph distributed this week at the U.S. Bureau of Reclamation’s 2014 Colorado River Annual Operating Plan consultation meeting in Las Vegas: That’s annual unregulated* inflow into Lake Powell on the Colorado River. A couple of things worth noting: 2012 and 2013 are two of only four years since Glen Canyon Dam was completed with …

update: A helpful reader had a correction: Hub Moeur was Gov. Moeur’s, nephew, not his son. Rats. previously: This evening, I snapped to the fact that J.H. “Hub” Moeur, the Arizona attorney who as chief counsel for the Arizona Interstate Stream Commission filed the 1952 brief in the seminal Colorado River case Arizona V. California …
The latest monthly Colorado River water management report from the U.S. Bureau of Reclamation (pdf) takes a major step toward the river’s first ever shortage declaration. We’ll know more in a month, but the preliminary estimates now show drops in the level of Lake Powell by the end of this year could trigger provisions of …

The folks at the University of Colorado’s Colorado River Governance Initiative have a clever idea to keep the Upper Basin states from getting screwed by climate change. Their new Upper Basin Voluntary Demand Cap white paper (pdf) offers a solution path for one of the stickiest problems in future Colorado Basin water management under climate change. In …
From the 1923 US Geological Survey’s Birdseye Expedition of the Grand Canyon. The full caption: Sheer walls in Marble Canyon. The rate at which this canyon burrows its way into the earth never fails to astonish the traveler entering it for the first time. Twenty miles below its head, the walls are 2,000 feet above …

With “Chasing Water” and “Moving Water” taken, the current working title for my Colorado River book-in-progress is “The Great Mistake.” It doesn’t have enough action verbiness for the final cut, but it seems to nicely frame one of my central themes – that the folks who built the elaborate plumbing system in the Colorado River …
