BLYTHE, CALIF. – It’s not quite the way I remember it. I suppose it never is. I’m on a reporting trip. I had some meetings in Phoenix today, then made a freeway dash out to the Colorado River for a few days of journalism-by-wandering-around. I ended up this evening near sundown in Blythe, Calif., dumped …
While the current snowpack numbers look lousy for Colorado River Basin runoff, a glimmer of hope for a late-season uptick in the latest Climate Prediction Center seasonal outlook. Green means “odd tipped toward wet”: I prefer to ignore, then the cognitive dissonance caused by this:
The new paper by Ben Cook and colleagues clarifying our understanding the risk of megadrought in the southwestern United States has rightly gotten a lot of attention. Combining paleo records and modeling of a changing climate under rising greenhouse gas scenarios, Cook and his colleagues have created some scary reading: [F]uture drought risk will likely …

January was bad for snowpack and therefore spring runoff in the Colorado and Rio Grande basins. February has been worse. But we don’t use water at the basin scale, we use it one irrigation district and city at the time. Here I will attempt to sum up the current snowpack and water supply situation and …

The Colorado Basin’s two primary reservoirs lost, on paper, a million acre feet of water because of January’s dry snowpack, according to the latest numbers from the U.S. Bureau of Reclamation. That’s the difference between what we expected to end the current water year with based on the January forecast, versus what the forecast looks …

Albuquerque meteorologist Brian Guyer, who seems to be as obsessed as I am with the early snowmelt, plotted up the latest flow in the Azotea Tunnel* this year, compared with the long term median: * Azotea delivers New Mexico’s San Juan-Chama Project water from a trio of streams in southern Colorado.
From yesterday’s New York Times: The problem with using ocean water to replenish the lake is that current agricultural runoff adds three million to four million tons of salt per year, Mr. Shintaku said. The same amount of ocean water would add about 10 times as much salt. As the water evaporates, the salt would …

Today’s high in Durango was 59F (15C), 18 degrees above the 1981-2010 average for Feb. 8. In the mountains to the east – the mountains that provide Albuquerque’s San Juan-Chama drinking water – the snow has already begun to melt. The snowpack there is lousy to begin with – 62 percent of normal for this …

January was dry in the water-producing parts of the Colorado River Basin. The official Feb. 1 forecast for the Colorado River above Lake Powell (the part of the Basin where all the water comes from) calls for just 80 percent of median April-July inflow. That’s a big drop from the Jan. 1 forecast, which called …

As near as I can tell, the American Civil Liberties Union has no particular stake in water policy. But the venerable champion of free speech is wading into the rancorous New Mexico debate over the possible diversion of water from the Gila River. Lauren Villagran writes (behind surveywall): The American Civil Liberties Union said Wednesday …
