According to the U.S. Bureau of Reclamation, warm February weather meant the earliest runoff in the 40-plus year history of the San Juan-Chama Project, which brings water from southern Colorado to the Rio Grande Valley of New Mexico. But “early” does not translate to “a lot of water”. San Juan-Chama Project contractors, the largest of …

Matt Weiser, who has ably served so many of us as a guide to the complexities of California water, is leaving the Sacramento Bee.
A guest post of sorts* from a group of prominent economists here in the western United States questioning the findings in a widely quoted report (pdf here) by a group from Arizona State about the potential economic impact if the Colorado River went dry: *********** A January 14th article in the Wall Street Journal reported …

As I empty the last of last month’s big snowstorm from my rain barrels onto the garden, I notice the water comes out more and more slowly. It’s a reminder of why power production drops as supply in our big reservoirs declines. Some tricky tradeoffs here:
Resilience is a system’s ability to absorb a shock and still retain its basic structure and function. Here, in one complicated table, is an example of the sort of institutional plumbing valves we need to build to increase resilience in the face of drought. It’s a table accounting for the Metropolitan Water District of Southern …

Parker Live, a news web site based in Parker, Arizona, seems to be engaging in a little bit of what Kathryn Sorensen calls “drought schadenfreude” here. Parker sits on the Colorado, at the head of a rich farming valley with some of the most senior rights on the river and big farming that has thus far …

The price California farmers can get for their almonds doubled between 2007 and last year, according to the U.S. Department of Agriculture. Strong incentive to plant more trees, drought notwithstanding:
Arizona’s state seal is a fascinating bit of iconography in light of the state’s uneasy relationship with aridity and developed water. A dam, a river and irrigated land are given center stage – water projects as state destiny. Today I learned the seal’s details are actually enshrined in the state constitution: In the background shall be …

Doug Obegi lays out an interesting argument about the implications of drought for the “Bay Delta Conservation Plan”, the California plan to build great water-carrying tunnels beneath the Sacramento-San Joaquin Delta for farms and cities to the south. On paper, the tunnels would be largely dry during drought years, to preserve salinity balance in the …
