Arizona’s superwaterwonk Sharon Megdal on the Colorado River’s “structural deficit”: We have a problem. Arizona, California and Nevada together use more water than normally flows to us. This is called structural deficit. It’s like living on a budget that regularly exceeds your income. The piece has lots more in it, a good lay primer on …

The standard Bureau of Reclamation map of the Colorado River Basin has a series of red-dashed slivers beyond the physical boundaries of the basin itself, the places where we’ve chosen to artificially extend the watershed’s boundaries. In the process, we have created entire communities dependent on the success or failure of the basin’s water management …

With just a few days left, it looks like Lake Mead will end 2014 down 19 feet, which would be the second biggest one-year drop of the “modern era” (the years since completion of Glen Canyon Dam upstream damped down the river’s ups and downs). With inflow largely regulated by Glen Canyon Dam and outflow largely …

Annie Snider left an excellent summary in our Christmas stocking of the state of play on the Colorado River. Lake Mead approaches the end of the Calendar year at elevation 1,087 feet above sea level, which is nearly 20 feet below last year at this time, as basin water managers scramble to build new institutional widgets …

Even with the release of extra water from upstream reservoirs, Lake Mead outside Las Vegas is forecast to continue dropping in 2015 and into 2016, according to the U.S. Bureau of Reclamation’s latest monthly “24-Month Study” (pdf). At this point, as Lake Mead drifts deeper into record emptiness, it goes without saying that the big …

So the folks at Island Press will be publishing my book, tentatively titled Beyond the Water Wars, about the problems facing the Colorado River Basin and how we might fix them. I couldn’t be happier. Its basic themes will be familiar to readers of this blog – the end of the age of fat reservoirs and full …

The International Boundary and Water Commission today released its initial science report (pdf) on this spring’s Colorado River pulse flow. A few key bits: When you add water, stuff grows. Satellite imagery in June ’14 compared to a year earlier showed a 36 percent increase in the Normalized Difference Vegetation Index. The NDVI increased in all …

tl;dr Everyone on the Colorado River has a legitimate argument that they’ve already sacrificed, and that they have a legal entitlement to what’s left. If everyone digs in their heels on these points, the system will crash. We need to be willing to share the pain. But (scroll to the bottom) there is hope on that …

The people of Arizona have come to look upon the officials of California, and particularly those of the Imperial Irrigation District and the Metropolitan Water District of Los Angeles as diabolical schemers who are dedicated to the robbery of Arizona’s birthright. That’s sometime Arizona political scientist Dean Mann, talking about the 20th century California-Arizona tussle …
A new collaboration among some of the serious names in Colorado River Basin water science and policy today launched a new project, the Colorado River Research Group. If you follow Colorado River issues and western water science policy, it’s a list of names (pdf) you’ll be familiar with and, more importantly, that you’ll want to …
