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 …
The Imperial Irrigation District earlier this month threw down a significant marker in the ongoing struggle to deal back overuse of Colorado River water with a petition to the California State Water Resources Control Board demanding action on restoration of the Salton Sea. The sea’s decline is one of the knock-on effects of efforts to …

I tend to hear the term “water buffalo” as pejorative – the old, lumbering water managers of a bygone era of dam-building and overconsumption. Not so, say the folks at the Central Arizona Project: Just what is a water buffalo? In Arizona, they are those iconic figures who had the foresight to plan ahead to …

We’re about 20 percent of the way into the fall-winter-spring snow accumulation season in the Colorado River Basin, and the current snowpack upstream of Lake Powell as estimated by the CBRFC is 61 percent of average: It is worth remembering, as the Bureau of Reclamation notes in its weekly water supply report (pdf), that “values …

I was wrong when I wrote in April that Lake Mead would continue to set “lowest ever for this point in the year” records for all of 2014. As I write this, with a few hours left in October, Mead’s surface elevation is 1,082.79 feet above seal level. That is more than five whole inches above …

Yesterday was the 78th anniversary of the first electric generator go into full operation at Boulder Dam. EDN has the story: Electricity from the dam’s powerhouse was originally sold pursuant to a 50-year contract, authorized by Congress in 1934, which ran from 1937 to 1987. In 1984, Congress passed a new statute which set power …
It’s generally more complicated than I think: A member of the Inkstain brain trust points out two catches in my “why can’t Phoenix just leave its unused apportionment in Lake Mead” post last week. The first has to do with Arizona’s application of the doctrine of prior appropriation with respect to its allocation of Colorado …
