Yes, think of what failed at Oroville. It was not the dam; it was the concrete spillway. Also, in California, we have had three dam failures of arch-gravity dam similar to Hover. Earth dams are less susceptible to damage from earthquakes which is a big deal that in California. We have serval dams in SoCal that are concrete that haven’t been maintained and are considered high risk of failure.
