Water and Power

The California Report has a great series on the relationship between Water and Power.

While much is uncertain about California’s warming climate, there is little doubt that it’s already changing the fundamentals of how most of us get our water. In fact, the Bureau of Reclamation has estimated that the Sierra snowpack could be reduced by half as soon as a decade from now.

And that has some far-reaching implications that could even show up on your electric bill.

“When you hear people talk about a depleted snowpack, it’s because of warmer temperatures and the snow just cannot stay in the hills,” says Robert Shibatani, a hydrologist and consultant to numerous government agencies. He says the “hydrograph” for California — the “usual” pattern of precipitation and runoff — is already changing. “There’s no question about it,” he told me in a recent interview. “That’s not an if. It’s not even a when, because I can tell you the when. It’s happening now.”
