OtPR today offers a list of generally poor rural communities that have seen domestic wells go dry as relatively affluent almond farms pump down regional aquifers to keep their orchards alive during the drought. It’s not hard to see why this is wrong: This economic model, in which powerful outsiders come in, displace the natives …

update: Jeff Lukas, in the comments, notes that I missed something important, which is the distinction between statewide averages and the east-west precip divide. As he correctly points out, that statewide blob of wet-looking Colorado hides the fact that it’s been extremely wet to the east, and relatively dry west of the continental divide. Here’s …

One of my happy new discoveries among people writing about water in this time of drought is a guy named Dan Macon, who raises grass-fed lambs in the Sierra Nevada foothills of California. Mason’s one of those people who depend on water from the sky rather than irrigation water from a canal or groundwater pump, …
March – July snowmelt runoff on central New Mexico’s Rio Grande, which provides the bulk of the river’s water, is forecast to be 44 percent of the 1981-2010 average, according to a federal forecast out this morning. The measurement point for that number is the Otowi Bridge, which is on the road from Santa Fe to …

Today it’s a deep dive into water markets, which includes this great explanation of why they’re so hard in practice: It’s tricky to show that the water you’re selling is …

Arizona lawyer Grady Gammage, a member of that state’s water establishment, opened a conference I attended last week with an explanation of why he became so engrossed in trying to understand “the Law of the River,” that bundle of laws and customs that govern the management and distribution of the waters of the Colorado River. …

The National Park Service with a warning for Lake Mead boaters as the big reservoir, a recreational favorite outside Las Vegas, drops to record lows: From the Park Service’s Lake Mead facebook page
Tina Shields, the Colorado River Resources Manager for California’s big Imperial Irrigation District, joked Friday about the newfound celebrity of the California almond. Used to be, alfalfa was the alleged water waster that got all the attention. “The best thing for alfalfa growers is almonds,” Shields quipped at one point during a Las Vegas Colorado …

I sent Lissa a picture from the Arizona side overlook of Hoover Dam this evening. Her response: “You can almost see its feet.” I drove out from Las Vegas to see Lake Mead and Hoover Dam this evening after a two-day Colorado River law and policy conference in a windowless hotel meeting room. Speaker after …
While we’ve all been obsessing over the elevation of Lake Mead, there’s a second looming lake elevation problem that could really complicate Colorado River management and increases the risk of a 2016 Arizona shortage declaration beyond the current estimates. Depending on how things play out over the next couple of months, this second problem could …
