About that whole peripheral thingie…

Matt Weiser reports the Brown administration* is backing away from a giant “Peripheral Tunnel” option for solving California’s bay-delta mess, or at least backing away from the notion that the big tunnel is The Plan: Gov. Jerry Brown’s top water official revealed Tuesday that a giant tunnel diverting water from the Sacramento River is no …

Flood memory half-life

Given the current flooding on the Mississippi, this from the Public Policy Institute of California’s discussion of flood risk in that state seems relevant: Perception of risk directly changes pressure for improving flood management. Longer periods of time since a natural disaster reduce the perception of risk—a phenomenon referred to as the “flood memory half-life.” …

Thinking about the Sacramento-San Joaquin Delta: click your heels together three times…

In trying to understand California’s efforts to deal with its Bay-Delta water problems, I’ve been digging into the Delta Stewardship Council and Bay Delta Conservation Plan processes, and frankly have been left feeling a bit like Dorothy upon her descent into Oz – lots of familiar cues, but over and over again things weren’t quite …

An Intriguing Way to Save Water

How China’s surging manufacturing sector helps save water in California: Although California’s population has continued to grow rapidly, water conservation activities and changes in economic structure (notably, less water-consuming manufacturing) have reduced water use enough since the mid-1990s to keep total gross urban water use roughly constant. From the PPIC’s “Managing California’s Water“

California Water: Pricing the Externalities

Economists have a useful framework for thinking about effects of an economic transaction that extend beyond the actors involved in the transaction. They call them “externalities”.

On that giant watershed

Now that I’ve got this “largest artificial watershed in the world” hammer, everything’s beginning to look like a nail. The “hammer” involves the notion that the vast artificial plumbing system we’ve built across the west has linked our water management fates in a way that did not exist when water tended to spend its human- …

Mike Connor on Delta Pumping

Watching California’s water argument from afar, I can’t help but see what looks like a remarkable failure to develop a process for juggling competing interests in the management of a classic common pool resource. From yesterday’s political theater drama House field hearing, here’s Mike Connor’s explanation of why it’s not a simple matter of just …
