High good, low bad: Mead in December 2010
The good news in the last hour of 2010 was that Lake Mead was 4.36 feet higher than the closing elevation for November. The bad news is that a winter bump is not unusual and, at ten feet lower than the closing December elevation for 2009 and at 40% capacity, the main storage reservoir on the Colorado River is 11.3 feet above a level that will trigger cuts for Arizona and Nevada.
Nerves are bad enough in the Grand Canyon State that the Arizona Republic reported this week that water managers are considering leaving part of their 2011 Colorado River allocation in Mead to forestall mandatory cuts. Larry Dozier, deputy general manager of the Central Arizona Project, told the Republic: “If we leave a little water this year, we won’t take the bigger hit the next year. Then we can take another spin on …

The Nevada water community chatter yesterday was about a new report ranking the Las Vegas economy as one of the worst in the world. It’s the first and hopefully the last time that I will see Las Vegas compared to Barcelona. However, the story that interested me was this one, in Monday’s Las Vegas Sun, about the suicide danger of the new Hoover Dam Bypass Bridge. It’s notable for two reasons. First is the stunning image by Sun staff photographer Sam Morris, who may be the most talented snapper working in the Western press. Second, I was struck by what wasn’t there. Why wasn’t there more concern about who will jump?
Anyone who has visited Las Vegas will know that …
High good, low bad: Lake Mead in October 2010
“The advice given to boaters here these days – ‘If you haven’t been to Lake Mead lately, you haven’t been to Lake Mead’ – sounds like a marketing slogan dreamed up to lure return business,” writes Shaun McKinnon in the Arizona Republic. “Except in this case the advice is true. The drought on the Colorado River has reshaped the huge reservoir so dramatically in the past 11 years that it bears little resemblance to the lake captured in snapshots just a few years ago. Water levels have dropped 133 feet. Islands have emerged and grown. Rocky outcroppings push through the surface, creating watery obstacle courses whose paths shift almost daily.”

High good, low bad: Mead in September 2010
Seventy five years ago, President Franklin Delano Roosevelt dedicated Hoover Dam. The concrete is looking good. The thing showing its age is the Colorado River water impounded behind it. The elevation of Lake Mead, the storage reservoir serving California, Arizona, Nevada and the Republic of Mexico, dropped last night to 1,083.83 feet, the lowest closing elevation for September since 1937. That year, the world’s then largest reservoir was still filling. Now its over-allocated water is steadily disappearing. Elsewhere in the Bad News Department, the river serving it is unlikely to be flush this coming winter according to a new study comparing drought stress evident from tree rings and ocean currents. Rather, in Long-Term Relationships Between Ocean Variability and Water Resources in Northeastern Utah, RAND Corp researcher Abbie Tingstad and UCLA geographer Glen MacDonald suggest…
High good, low bad: Mead in August 2010
There may be a plan in place to keep the West in water in the face of climate change, population growth and sluggishness to conserve. Or there may simply be plans for plans. The image above comes from a federal Bureau of Reclamation May 2010 Tribal outreach PowerPoint to do with supply and demand on the Colorado River.
To quote retired General Stanley A. McChrystal’s remark about another PowerPoint, “When we understand that slide, we’ll have won the war.”
As for the current state of our shrinking Colorado River reserves, with apologies for the lateness of what should have been a September 1 posting, after the jump are the last 10 closing August elevations for the reservoir serving Arizona, Nevada, California and the Republic of Mexico as reported by the master of the river. The closing August 2010 elevation of Lake Mead was 1,086.91, the lowest since 1956. Click here…
