From this morning’s newspaper, a look at the coming trouble among farming, fish, cities and water in the Rio Grande: [W]ith farms and cities diverting water from the river to meet their needs, leaving enough for the fish and the ecosystem on which it depends while at the same time meeting human needs has become …

If one allows mining of a nonrenewable source, it is disingenuous to argue that the source should never be polluted if the economic activity causing the pollution is necessary to sustain employment. Suppose that two individuals proposed to extract water from a nonrenewable aquifer. The first agreed he would farm and by doing so dry up the aquifer. …
From this morning’s Albuquerque Journal, my distillation of the Colorado River Basin Study’s key message: Towing icebergs from Alaska or building a giant pipeline from the Missouri River won’t bail out the western United States from its growing water supply crisis, federal officials said Wednesday. Instead, conservation by the region’s farms and cities offers the …

New Mexico’s 2012 weather feels increasingly like a teachable moment, though the lessons must be handled with care. As the folks in the local media-weather complex went into stormpocalypse mode over the possibility that it might actually snow this weekend, I took pause in Saturday’s paper to look back: The storm comes as New Mexico …
Regular readers will know of my obsession with pushing beyond the “OMG we’re running out of water!” story line to look in detail at who, specifically, gets shorted when supplies run low and what adaptive responses they have available. In New Mexico, water managers are using the occasion of our current drought to helpfully prepare …

Another episode in my effort to explore the meaning of “drought” by way of example. Up on Albuquerque’s north side is a spot the birders call the “Tramway wetland”*. It’s the spot where the main flood control channel for much of Albuquerque slows before entering the Rio Grande. The local flood control authority has designed …

From the work blog, some material from a discussion among drought researchers on the Sheffield Nature paper and the question of when the Palmer Drought Severity Index is or isn’t the right tool for the drought measurement job. Here’s Dave Gutzler: Despite its many limitations PDSI is still a meaningful indicator of short term climate …

From Saturday’s newspaper, my story about a state court ruling against a proposed groundwater transfer case in New Mexico: State officials made clear Friday that, while they ruled against this application because of its failure to specify where and how the water would be used, they do not in general oppose water transfers around the …

When the federal government and the seven US states that share the Colorado River signed their 2007 “Interim Guidelines for Lower Basin Shortages and the Coordinated Operations for Lake Powell and Lake Mead,” the final Record of Decision (pdf) included several chunks of legalese to the effect that the deal, while binding on the US …

Just the blog equivalent of thinking out loud here. It’s not that this data was surprising to me, so much as that I wasn’t sure what to expect. Four cities in the western United States with some similar characteristics – arid climate, water supply challenges, growing populations. Each of the four is the dominant population …
