Stuff I Wrote Elsewhere: Dry Times Ahead in the West
From this morning’s newspaper (sub/ad req), a story about the new paper in today’s Science by Jonathan Overpeck and Brad Udall about climate change in the West. Udall and Overpeck have become fixtures on the western water meeting circuit over the last several years delivering this message, and the paper contains no real surprises. But …

River Beat: Chances of Mead Hitting 1075
I’ve written in the past about the remarkable fact that, despite the 10 driest years on record on the Colorado River, no one’s had their allocation reduced or cut off. The first plausible scenario under which that would change happens when the surface of Lake Mead drops to 1,075 feet above sea level. Under the …

River Beat: The Conversation About Limits
The suddenly ubiquitous Bureau of Reclamation Colorado River supply-demand graph showed up today in a helpful Bruce Finley story in today’s Denver Post about the conversation in Colorado regarding the disconnect between shrinking Colorado River supply and growing Colorado River demand: Colorado River water consumed yearly for agriculture and by the 30 million Westerners who …

River Beat: Up to Driest 11 years on the Colorado
This observation from the first draft of next year’s U.S. Bureau of Reclamation Colorado River Annual Operating Plan should come as no surprise: Inflow to Lake Powell has been below average in nine of the past eleven years (2000-2010). Although slightly above average inflows occurred in 2005 and 2008, drought conditions in the Colorado River Basin persist. …

River Beat: Water Level Update
At the end of the beneficent water year of 1983, Lake Mead, the giant reservoir behind Hoover Dam that manages water for the benefit of Nevada, Arizona and California, held 25.7 million acre feet of water. At the end of water year 2010, according to the latest forecast, there will be less water than that …
River Beat: Huntington Beach, CA, Poseidon Desal
David Zetland calls the cost of desalination the “backstop price” for water. Once the cost of other sources rises sufficiently, coastal residents will just build desal plants because it’s cheaper. While the fungibility is not complete (i.e. we don’t all live on coasts), water trades could allow people who live inland to play too. This …

LDS Church Protests Vegas Water Deal
Given the remarkable role of the Church of Jesus Christ of Latter Day Saints in western U.S. water history, it’s at least of symbolic importance that the church is among those who have filed protests against Las Vegas, Nevada’s proposal to build a pipeline to pump water from the Snake Valley to the growing gambling …
Colorado River Forecast in a Nutshell
River Beat: 2010 snow season all over save the melting
The June 1 Colorado Basin forecasts are out, and, as expected, there’s been no miracle. The inflow into Lake Powell looks pretty much exactly like it did a month ago, minus the chance of a miraculous late snow rescue or the flip side chance of some sort of terrible collapse: The blue bar is average, …
