I was reminded at a talk last night that farmers in the Elephant Butte Irrigation District in southern New Mexico got less than 10 percent of a full irrigation allotment last year. I say that by way of a preface to noting Juliet McKenna’s observation that there’s a 50-50 chance of a formal shortage declaration in …
I suppose it’s a sign of the times on the Colorado River that a January forecast of 95 percent of average flow into Lake Powell counts as good news. Since green on the Colorado Basin River Forecast Center map runs from 90 to 110 percent, we get green. It’s only a little bit below average! …

From the U.S. Bureau of Labor Statistics: Yuma, Ariz., and El Centro, Calif., had the highest unemployment rates in October, 31.9 percent and 25.2 percent, respectively. These folks are getting a lot of Colorado River water. There’s seasonality to the resulting ag work economies, but really, this is a graph of economic suckage:
According to the U.S. Bureau of Reclamation’s new Consumptive Uses and Losses Report (pdf), consumptive use of Colorado River water in the states of the upper basin (Colorado, New Mexico, Utah, Wyoming and a sliver of Arizona) reached 4.281 million acre feet in 2011, the highest on record. The previous high was 4.245 million acre …

From Jonathan Overpeck last month in Nature (gated): The complexity of these megadroughts still defies complete explanation and yet it implies that unusually persistent anomalies of sea surface temperature can combine with amplifying changes in vegetation and soil to drive droughts that — if they happened today — would outstrip many of our institutional capacities …
On this holiday, we can give thanks that the snowpack in the Upper Colorado River Basin is more than twice as big as last year at this time. It’s actually (#dontjinx) above average:
In Scottsdale, AZ, there’s a business called Desert Cadillac. It sells cars, apparently without irony.
tl;dr – In 1960, U.S. Supreme Court Special Master Simon Rifkind made a fundamental mistake in calculating how much water was then available in the Colorado River Basin, and how much might be available in the future. The court, in its ruling in the case of Arizona v. California, accepted Rifkind’s math. The consequence is …

Does this simply represent hardening of demand – the result of low-hanging conservation fruit being mostly all plucked? Or does this suggest arid Arizona is not headed toward the big water-driven economic collapse some people fear?
Circa 1958, a unique argument in favor of the development of the next wave of dams in the Colorado River Basin. At the time, the Eisenhower administration had failed to include any “new starts” for U.S. Bureau of Reclamation projects in its Fiscal Year 1959 budget. Sen. James E. Murray, D-Montana, was alarmed: Your attention …
