Looks like the spillway’s about 150’ wide.
I wonder how practical it would be to pack the hole full of quick-set cement and bolt a lot of steel plates over it.
Then, seal the edges of the plates with some sort of asphalt, and put an aererator pipe upstream of it to minimize the cavitation/erosion of the water flowing over it.
You have some good suggestions but considering that this is in California the environmental impact studies prior to any repair work would probably take at least 15 years.
Great questions: They have to use the emergency spillway, to get to and dry out the main spillway.
Apparently, this isn’t a new problem and funding was supposedly made available a couple of years ago.
However, apparently, in typical Moonbeam/Rat legislature, they funded the bullet train from nowhere to nowhere and of course illegal health care and other goodies.
We have a respite from big storms until later next week. That could be a mother of a storm with tons of rain and no place for it to go.
Apparently, the expensive aka good long range weather predictors are saying we will have an excess of rain until the end of March.
