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 …

Popular activities at the Salton Sea State Recreation Area include boating, water-skiing, fishing, jet-skiing, hiking, birdwatching, and sailboarding. It is estimated that over 1 million visitors spend time at …
From a June 13 appearance on KNPR in Las Vegas, NV, with Pat Mulroy and Robert Glennon: States have resorted to lawsuits, and even military action to protect water sources in the past. Lawsuits have a huge downside, and can cost municipalities access to water if they lose. “What we’ve seen going back to the …

Lake Powell, the large Upper Colorado River Basin Reservoir sitting behind Glen Canyon Dam, ended May with a surface elevation of 3,599.44 feet above sea level, 3 feet higher than projected a month ago, thanks to greater-than-anticipated runoff during the month. Some of that’s just time-shifting – an early melt bringing water down sooner than …

update: Michael Cohen at the Pacific Institute emailed with a subtle clarification. If Lake Mead, as the USBR analysis reported below suggests, drops below elevation 1,075 feet above sea level during 2015, the actual shortage declaration on the lower Colorado would then apply to the following year’s water allocation. More specifically, during August the Bureau …
