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 …

The Bureau of Reclamation today named Brent Rhees to head its Salt Lake City-based Upper Colorado office: As deputy regional director, Rhees managed several complex and high profile issues, including the Middle Rio Grande Endangered Species Collaborative Program, dam safety modifications, implementation of the Navajo-Gallup Water Supply Project, the Colorado River Salinity Control Program and …

Water journalist Brett Walton wrote a lovely piece about finally meeting the Colorado River for the first time: I have reported on the Colorado River for five years. I know it as a legal argument, as a topographic feature, as an obstacle, and as a matrix of charts, calculations, and grim projections. I’ve read its …

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 …

USDA estimates of revenue from California crop production (excluding horticulture) in recent years. I know just enough about this data to be misleading or dangerous, so I make no claims, but it sure seems interesting. Source: USDA NASS
Lea-Rachel Kosnick, in a paper a few years back, described the “tragedy of the anticommons”. In a classic “tragedy of the commons,” every pumper is sticking their straw into an aquifer and sucking it out, with no incentive to conserve because the other folks will just take the rest anyway. In the “anticommons” example, there …
