High Good, Low Bad: May Elevations on Mead
Lake Mead is the Colorado River Reservoir holding water supplies for California, Arizona, Nevada and Mexico. The maximum elevation is 1,229 feet. Below, gleaned from US Bureau of Reclamation records, are year-on-year May elevation reports going back to 2004. Also borrowed from Reclamation is a nifty graphic published on Friday, May 8, 2009 showing April and May 2009 elevations. The May elevations were largely estimates (in yellow). Kudos to the graphic artist. The actual closing elevation for May 31, 2009 was 1,096.92.

Vegas Draws Line on Mead Lakeside as Trigger Point to Build Pipeline to Great Basin Ground Water
JUST in case any of the board members of the Southern Nevada Water Authority have become squeamish lately about mining the Great Basin Aquifer to sustain growth in Las Vegas, they have been given a deadline to approve building the 300-mile-long pipeline that they will need to pump the Great Basin’s ground water water south. The deadline will come when the elevation of Lake Mead, the Colorado River reservoir that currently supplies roughly 90% of Las Vegas’s water, drops another 23 feet or reaches 1,075 feet.
From today’s story by Henry Brean in the Las Vegas Review Journal:
- Board members have already approved the pipeline concept and signed off on ongoing efforts to secure water rights and environmental permits, but they have never actually voted to build the project
- That decision will come if, or perhaps when, the surface of Lake Mead sinks to elevation 1,075, a low-water mark

“Huge Signal” of Change from Columbia River Salmon

BONNEVILLE DAM – Run of small salmon on the Columbia River baffles anglers, scientists, Seattle Times. ”Just looking at the Bonneville Dam count, it’s extraordinary,” says Brian Beckman, a National Marine Fisheries Service biologist in Seattle. “It’s just kind of jaw-dropping … There is a huge signal from the fish that something has changed.”…
Nevada Supreme Court to Judge State Engineer
ASK any of the rural Nevadans who stand to lose their water to Las Vegas and its proposed 300-mile pipeline into central Nevada if the proceedings were fair, and they will laugh at your naivete. For them, Las Vegas gamed the table before the rural communities even knew that a game was on. One of their last recourses to stop the pipeline is a suit coming before the Nevada Supreme Court on Monday at 10.30am.
The court’s summary of Great Basin Water Network versus the State Engineer of Nevada reads: “In 1989, the predecessor to the Southern Nevada Water Authority filed applications for unappropriated water rights from rural Nevada for use in Las Vegas. More than 800 interested persons filed protests. In 2005, the State Engineer notified roughly 300 of the interested persons that a prehearing conference would be held to discuss the water rights applications. Some organizations and individuals …
