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.
They should tear it down and start over with a concrete dam if they get through this season.
Concrete is actually less safe than a earth dam. The problem with Oroville is poor maintenance and poor design of the secondary spillway.

I would open it up to the free market to compete in ways to fix these types of problems. Get the government out of it.
On the bidding side, maybe. But, dam safety is one place where I actually believe in some type of centralized oversight.
It is like New Orleans. If it might flood, don't build there.
I agree.
