California’s water problems will never be solved Faith Kerns and Doug Parker argue, because cities and farms will always expand to the edge of available supply, overshoot, and then face trouble during the dry times: There are other arenas where this phenomenon is well understood. For example, when it comes to freeways, congestion leads to demand …
If you follow weather forecasts, you’ve heard about “relative humidity” (RH). But it’s one of those maddeningly less-than-useful measures of our weather that probably needs to be just retired. That’s wishful thinking, of course. But in an interesting introduction to their latest research into the increasing dryness of the air and the risk of fire …
The culture of federal water projects has trained state interests, like a puppy to a dog biscuit, to believe that the federal government has limitless federal largesse and that no contract term will ever be enforced against state water project interest. Robert Glennon, writing two decades ago, in Coattails of the Past: Using and Financing the …
Folks worried that Lake Mead might drop below elevation 1,075 and trigger a first-ever Lower Colorado River Basin shortage now have more to worry about.

The break between population, economic growth, and water use is something Peter Gleick has pointed out …

Alfalfa, which recently handed over its”Demon Crop” title to almonds, is really a far better crop in drought than common wisdom suggests, according to U.C. Davis’s Dan Putnam: Contrary to popular belief, alfalfa has several unique positive biological properties and advantages when it comes to water. Due to these properties, alfalfa is remarkably resilient when …
In Phoenix for a meeting, I had a couple of hours’ hole in my schedule and skipped out to the “Gilbert Water Ranch”. It’s an interesting example of what the water management solution space looks like in arid central Arizona. It’s a series of groundwater recharge basins in the Phoenix suburb – both treated municipal …
It’s a nuance, but of such subtleties are progress often made. In the Bureau of Reclamation’s new “Moving Forward” report on the future of the Colorado River Basin, a subtle change to the bureau’s canonical map: There, at the bottom.
