From Jay Lund, a comment on my post last week about low flows into that is worth elevating: Perhaps a bigger issue is that average unimpaired flow appears to be < 11 maf, but total allocations are more than 16 maf/year (1.5 maf/yr for Mexico and 7.5 maf each for the upper-basin and lower-basin states). …

I got what may be my all time favorite reader comment a couple of weeks back when I tried to explain that the summer rains New Mexico has been getting do not mean our drought is over: This article is miserablism at its absolute worst. How about looking at important progress in reservoirs like Conchas …

Emily Green: The cheapest source of new water is being less wasteful with old water.

Here’s a striking graph distributed this week at the U.S. Bureau of Reclamation’s 2014 Colorado River Annual Operating Plan consultation meeting in Las Vegas: That’s annual unregulated* inflow into Lake Powell on the Colorado River. A couple of things worth noting: 2012 and 2013 are two of only four years since Glen Canyon Dam was completed with …

In the arid west, increased irrigation efficiency is one of the most commonly suggested solutions to our water problems. But Jay Lund and Thomas Harter point out the dilemma: In many areas, drought-year groundwater supplies depend substantially on irrigation inefficiency in wetter years, when surface water is available and used by farmers. Ironically, local inefficiency …
There’s a little concrete check dam in Albuquerque’s riverside woods at the bottom of a pond built by humans as wildlife habitat. Among the wildlife that has taken up residence is a family of beavers, who have built a palatial home on the island in the middle of the pond. But they seem dissatisfied with …
As I learn about the development of large-scale water management institutions in regions other than my own (the southwestern United States), I’m increasingly convinced that our oft-discussed tradition of conflict – Marc Reisner famously described the Colorado as “the most legislated, most debated, and most litigated river in the entire world” – may really be viewed …

Here’s another look into the western water solution space – an agreement on the Lower Rio Grande under which willing farmers will have a chance to sell their water rights for use recreating lost riparian habitat (story behind survey wall for non-subscribers): To the list of the Lower Rio Grande’s famous crops, like Hatch’s chile …

The latest monthly Colorado River water management report from the U.S. Bureau of Reclamation (pdf) takes a major step toward the river’s first ever shortage declaration. We’ll know more in a month, but the preliminary estimates now show drops in the level of Lake Powell by the end of this year could trigger provisions of …
