If I was trying to manage water in California, these maps would give me the heebie-jeebies. It’s from a new paper (AGU-walled) by Zion Klos and colleagues extending our knowledge of the shift from snow to rain in the high country of the western United States as a result of warming temperatures. Here’s why this …

The state’s first protracted drought occurred in 1868 and lingered on until 1872 or 1873. The west side of the San Joaquin Valley suffered most. There the wheat crop was a total loss in 1870 and 1871, and by the fall of the latter year the parched valley had turned to dust…. [B]anks foreclosed on …
It seems like a no brainer. Stop wasting that water! Put it to good use! But when we’re talking about things like lining irrigation canals (see for exmample the All-American Canal saga, pdf here) or cleaning up and re-using sewage, it’s critical to ask the question: If we don’t do this, where will that water …

Simply put, no environmental law has had as much impact on western rivers–or created as much controversy–as section 7 of the ESA. – Reed Benson I’m on record as arguing that the Endangered Species Act is a terrible water management tool, while simultaneously being not terribly effective as an environmental tool. But you manage water …

Driving up through the Imperial Valley in March, I chanced upon this example of the fading hopes of the town of Brawley. In his maddeningly intriguing book Imperial, William Vollman briefly slips out of the obtuse into this rare moment of clarity: When I began to study the history of the period, my mind remained …

But man has in measure changed the desert conditions by storing the waste waters of the mountains and reclaiming the valleys by irrigation. His success has been phenomenal. Out of the wilderness there have sprung farms, houses, towns, cities with their wealth and luxury. But the cultivated conditions are maintained only at the price of …
One of the fundamental propositions of date culture is that the palm requires a large supply of water for irrigation. This rule is apparently subject to some striking exceptions and future experiments will probably change our ideas on the subject still more, though they can hardly shake the fact that the palm is a water …
The AP’s Jason Dearen has an update on California communities at risk of running out of water: In February, the California Department of Public Health listed 17 mostly rural water systems as having less than two months water supply in storage. But in recent weeks that number has fallen to three. In February, as media …
