Here in the southwestern United States, we’re gearing up for a big blast of El Nino weather, with some areas in California expecting a pounding. But as we desert dwellers dig through closets looking for our underused umbrellas, it’s worth remembering how dry it’s been. That’s percent of normal precip since Oct. 1, courtesy NOAA:
The folks at the U.S. Bureau of Reclamation have crunched the numbers on how the latest 2010 Colorado River runoff forecast will affect the river’s major storage reservoirs, and the news is not good for Lake Mead. At this point, according to the Bureau of Reclamation, there is just a one in five chance that …

Tony Davis reports in this morning’s Arizona Daily Star that the Central Arizona Project could see a shortage in its Colorado River allocation by 2012: For decades, most water experts have expected the Central Arizona Project to eventually run short, as population growth outstripped the supply of the Colorado River that long ago was over-allocated …

The January Colorado River forecast for 2009-10, out last Friday, is the lowest at this point in the year since 2002-03: The range of uncertainty right now is enormous. In an average year, about 8 million acre feet flows into Lake Powell in the April-July period, which is the peak of the runoff season. This …
Tramway (Not So) Wetlands Originally uploaded by heinemanfleck. January’s a time of quiet and anticipation. What water there is in our rivers is mostly what they call “base flow”, which is really just the surface manifestation of groundwater leaking into the river channel. Or they’re just dry. The runoff to come is frozen in the …
About five seconds with the google is enough to make one question the old alleged Twain chestnut: “Whiskey’s for drinking, water’s for fighting about.” Is that too much to ask, Mark Strassman? Especially given how not only factually wrong but conceptually misleading the reference is? Whiskey, yes, but water is frequently not for fighting about, …
Southwest Hydrology, the invaluable University of Arizona publication that is a frequent starting point when I’m researching an unfamiliar water topic, has lost its National Science Foundation funding and will be closed, Shaun McKinnon reports: The magazine’s demise was announced in notes written by founding editor, Betsy Woodhouse and Gary Woodard, associate director of the …
It has long been apparent that the water supply of the Colorado is inadequate for all the demands that will be made upon it, as is the case with many other streams in the West. That is G.E.P. Smith of the University of Arizona, writing in the Proceedings of the American Society of Civil Engineers …
As an addendum to Emily Green’s year-end look at Lake Mead (High good, low bad) I’d like to extend the analysis back a bit farther in time. Emily points out that, while population has risen over the past decade in the region served by Mead (one of the two large storage reservoirs on the Colorado), …
David Zetland posted on the Salton Sea today, arguing that we should just give it up: Today’s Salton “Sea” is NOT natural. It’s replenished by irrigation runoff, of dubious quality. As water evaporates, it leaves behind higher concentrations of salts and other nasty stuff. Time to dry out the Salton Toilet, clean up the mess …
