Updating my Colorado River reservoir storage spreadsheet today to make a graph for a friend was a pretty discouraging exercise. Lake Mead and Lake Powell, the system’s two massive reservoirs on which 9 states and a gazillion people and farm acres depend, are at their lowest combined level since 1967, when they were filling Powell …

We need to create a #WestWaterSyllabus. Mark Hertsgaard at the Daily Beast got a lot of traction this weekend with a piece suggesting this: If You Only Read One Book About the Water Crisis: ‘Cadillac Desert’.

There are seven states in the U.S. and two more in Mexico that depend on the Colorado River’s water. Here, from Sandra Dibble, is a reminder that when shortage descends, it is not just Arizona (as I have been guilty of saying) that takes the first hit: In Mexico, the first impact of cutbacks on …
