Craig Miller at KQED has a useful roundup of what sort of shortfalls California water users might see this summer as a result of drought: Ag: “More than 400,000 acres of farmland were fallowed last year because of scarce water.

California farmers by now have a pretty clear picture of what their water supply situation is going to be this year, whether it’s reservoir and irrigation system surface delivery, or groundwater pumping. The U.S. Department of Agriculture today released projected acreage for the state’s major field crops (pdf) that reflects farmers’ resulting choices: corn: 430,000 …

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:
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 …

The little town of Huron, California (Fresno County, population 7,000) is on the brink of running out of water. Its plight to illustrates a broader point about “running out of water”. First, its story courtesy of the Central Valley News, which reports that Huron could run out of water by July: Huron, a rural farming …
