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 …
Fourteen years after Hoover Dam’s gates were closed, U.S. Geological Survey scientists found earth’s crust beneath the dam had sunk 4 inches because of the weight of its impounded water: That’s from Geological Survey Circular 346, First Fourteen Years of Lake Mead, 1954 (pdf), ht Kyle House
The negotiation of the 1922 Colorado River Compact governing the allocation of water from the West’s great river, and the ratification process that followed, was a politically delicate process. Precisely how delicate is made clear in a fascinating exchange of letters 10 years after between Colorado attorney Delph Carpenter (the compact’s primary architect) and Norcutt …

Reed Benson has read the CRomnibus, the ginormous federal spending bill approved late last year as Congress was heading out the door, and helpfully digested some of the key water policy bits so the rest of us don’t have to. For the Colorado River, the bill… allows the Bureau to “fund or participate in pilot …

Lest our city shrivel and die, we must have more water, we must built a great new aqueduct to the Colorado. William Mulholland, Los Angeles, 1925, as quoted in Vincent Ostrom’s Water and Politics
