I posted a note about this recently, but I want to revisit it today. BRT Insights - Whitewater Kayaking has posted additional information about the proposed Auburn Dam on California’s American River. Let’s start with this concise overview of the risk to downstream residents of a new dam on the American. Professors Tony Finnery and Jimmy L. Spearow, in their article, note the following:
An even worse man-made disaster would threaten Sacramento if an Auburn Dam is built. Because there are no more good dam sites in the region, the original Auburn Dam was being built at a risky location within the Bear Mountain fault zone. When the northward extension of this fault ruptured near Oroville in 1975, causing a magnitude 5.7 earthquake, construction was halted in Auburn.
The U.S. Bureau of Reclamation, which builds and operates many large dams, concluded that the 685-foot high, thin-arch concrete dam they had started to build would not withstand an earthquake of the size predicted by these studies. So, they abandoned that dam and proposed a new, massive and terribly expensive concrete gravity dam instead.
Some people will make a lot of money if an Auburn Dam is built, not only from the construction project, but also by selling water and hydro-electric power, and building housing developments. Because of these special interests, the issue of restarting an Auburn Dam never dies.
And note this as well:
A Bureau of Reclamation study in 1980 confirmed this scenario, predicting that a failure of an Auburn Dam, when full, would send a nightmare wave surging across the Sacramento metropolitan area, topping the Folsom Dam within five minutes, then sweeping 70 feet over the Nimbus Dam. It would hit the federal building on Cottage Way in one hour and 40 minutes, peaking at 46-feet deep. The flood would hit the Capitol building in two hours and six minutes, peaking at 40 feet. Such deep and turbulent flood waters likely would overtop and destroy many houses, lowering chances of rooftop survival.
Rivers are critical for our environment, wildlife habitat, recreation, drinking water, irrigation water and flood control. Water development projects should be scrutinized carefully to minimize environmental impacts and use taxpayer dollars efficiently.
Why is that so hard for some folks to comprehend?
Because, as BRT Insights notes:
An Auburn Dam porkbarrel project would enrich a few contractors who would build it, a few landowners whose property would be along the shore of a new reservoir, and a few more landowners who could develop housing subdivisions based on water from a new reservoir. These few powerful people will continue to fight for their porkbarrel project forever with the help of local politicians who are willing to work against the greater public good.
