Decades of dry on the Rio Grande

Seventeen of the last 20 years have had below-average runoff at Otowi (north-central New Mexico) on the Rio Grande: That’s from the U.S. Bureau of Reclamation’s 2015 Annual Operating Plan presentation, done in Albuquerque last week. “Average” is the 1895-2014 mean.

On the Rio Grande drought, not exactly optimism, but not pessimism either

Michael Wines in Monday’s New York Times: The perils of drought are on ample display along the Rio Grande, where a rising thirst has tested farmers, fueled environmental battles over vanishing fish and pushed a water-rights dispute between Texas and New Mexico to the Supreme Court.

There is a natural desire in water-short communities to capture and use stormwater. But a brewing feud between the state of New Mexico and the U.S. Environmental Protection Agency is a reminder that tweaking the stormwater management system is not without consequences, because the water you’re capturing would otherwise be going somewhere and doing something. …
