Before we abandon LA because of water shortages, we’ll do this

Posted by on

From Juliet McKenna, another example of the lengths to which southwestern municipalities will go to adapt to shrinking water supply: LA’s plan calls for building one of the country’s largest groundwater treatment systems at one of its largest Superfund sites. Groundwater in the San Fernando basin has elevated levels of chromium, perchlorate, nitrates, and trichloroethylene …

the irrigation efficiency dilemma

Posted by on

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 …

Via Henry Brean, Pat Mulroy shares her views of the Imperial Irrigation District’s efforts to funnel water into the Salton Sea: Mulroy is definitely worried about Lake Mead, which supplies about 90 percent of the Las Vegas Valley’s drinking water. But she also voiced broader concerns about river water being used to prop up a …

Water’s for not fighting over?

Posted by on

If men will fight over water, they will also cooperate to conserve it and the history of water controversies is that, in the long run, the rule of cooperation prevails. Yet another nugget from my current favorite book, Carey McWilliams’ California: The Great Exception. Do you think he’s right? (The quote’s the opening of a 1949 …
