Water Supply

As the Sacramento Bee reports, this is going to be a very bad drought year and conservation is only one of the tools for adequate water in California, the other is storage and the plans for storage have been available since the 1960’s.

Along with the obvious solution for our area, the building of Auburn Dam which would double our storage capacity—but now appears to be off the table though congressional action can restore it—there is another that would solve the water problems for the larger region and that is the raising of Shasta Dam to its originally engineered height of 200 feet higher than it now is, tripling its water supply, which an article from the Los Angeles Times describes.

“From an engineering standpoint, it's a piece of cake. The dam, built between 1938 and 1945, was originally planned to be 200 feet taller. At 800 feet, it would have been the highest and biggest in the world.

“Sheri Harral, public affairs officer at the dam, said World War II and materials shortages associated with the war effort led to a decision to stop construction at 602 feet.

"The thinking was to come back and add on to it if ever there was a need to," Harral said. "They started looking at raising it in 1978."

“If Shasta Dam had been built up to its engineering limit in 1945, it is arguable that Northern and Central California would not be facing a critical water shortage now.

“According to a 1999 Bureau of Reclamation study, a dam 200 feet taller would be able to triple storage to 13.89 million acre-feet of water.”

An excerpt from the Sacramento Bee article.

“Water experts are having a hard time finding the right words to describe what lies ahead, after recording a dismally dry January in California.

"Scary," "grim," and possible "conservation mandates" are offered up.

“Yet it's easy for the experts to sound out a clear warning: This may become, simply, the worst drought California has ever seen.

"Our worst fears appear to be materializing," said Wendy Martin, drought coordinator at the state Department of Water Resources. "It's going to be a huge challenge."

“The bottom line, water officials said, is that right now, everyone must start using less water. The public can expect higher water bills and fines if they don't, because the alternative is a real water shortage – one that is threatening tens of thousands of Valley jobs.

"It's pretty scary," said Tim Quinn, executive director of the Association of California Water Agencies, who has more than three decades in the water-supply business. "The public needs to tighten their belts. You have to rearrange all the molecules in your brain to think about using water differently."
