Hoover Dam from above

I believe that anyone who flies in an airplane and doesn’t spend most of his time looking out the window wastes his money. – Marc Reisner When your vantage point spans a sufficient chunk of landscape, Hoover Dam doesn’t look so big. Is this really the right scale at which to think of it?

Stuff I wrote elsewhere: Kirtland jet fuel spill

I dashed out of town early Wednesday and failed to share with Inkstain readers the latest in the Kirtland Air Force Base jet fuel saga: As much as 24 million gallons of jet fuel might have escaped from a decades-long leak in an underground Kirtland Air Force Base pipe, three times more than previously estimated, …

Time-of-day watering restrictions in Tucson

From Douglas Kupel’s history of Arizona water, the story of Tucson’s efforts to conserve supply against rapidly rising demand. One thought – regulating outdoor watering: [T]he city council discussed a plan to limit all such irrigation to between six o’clock in the evening and four o’clock in the morning. The year was 1893.

Perhaps, then, the word “drought” is not …

The US Bureau of Reclamation this afternoon released its latest pass at quantifying water demand in the Colorado River Basin. Recognizing that there’s no one answer for what the demand curves might look like in the future, the agency looked at a range of six scenarios, based on input from the seven basin states on …

Groundwater mining in Saudi Arabia

NASA’s Earth Observatory folks posted a remarkable series of Landsat images today of the growth of groundwater pumping in Saudi Arabia’s Wadi As-Sirhan Basin. They’re drilling deep, and the NASA folks report it’ll be economical to continue pumping for about 50 years.        

Another take on Colorado Basin failure mode concludes that Arizona and Nevada are the trouble spots

Wildman and Forde make my last post on this subject look smart, arguing that the supply-demand imbalance on the Colorado River will hit Arizona and Nevada first: We find that initial shortages will be borne only by the cities of Arizona and Nevada and farms in Arizona whereas the other Basin states have no incentive …
