>>The topography is flat.A breach in this dam would send a 200 foot high wall of water down US 99
Let’s dial down the fear and realize that dams don’t simply evaporate instantaneously when they fail. Instead, they fail by degrees, they do not send 200’ walls of water down the valley. This image is designed to create hysteria and is the mental process that underlies “fake news”. There will be flooding, but no 200’ wall of water. (rolls eyes, smacks forehead, walks off muttering)
At 10:39 p.m., a massive landslide of about 260,000,000 cubic metres (340,000,000 cu yd) of forest, earth, and rock fell into the reservoir at up to 110 kilometres per hour (68 mph), completely filling the narrow reservoir behind the dam. The landslide was complete in just 45 seconds, much faster than predicted, and the resulting displacement of water caused 50,000,000 cubic metres (65,000,000 cu yd) of water to overtop the dam in a 250-metre (820 ft) high wave.[1][2]Hopefully, that won't happen here. Byrne's book was written with the local geography around Sacramento in mind, and described the result of a failure like this in pretty graphic detail. (He was an engineer by trade, and researched all of his books very thoroughly.)
Ever see the movie “Dam Busters”? :)
