Concrete is actually less safe than a earth dam. The problem with Oroville is poor maintenance and poor design of the secondary spillway.

Hoover is less safe than Oroville?

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.
