Juan deserves some kind of journalism award for his work on the Oroville Dam. Just the facts and no BS with a great delivery.
He does a good job.
One thing seemed a little vague. He asked about the RCC in the canyon having retaining walls on the left side (7:10). The answer was “the design has training walls on both sides”. This sounds like there is an intention to use the canyon, that the canyon will be filled with RCC to an already determined level, that it will have walls, and that it will be used. I thought the plan was to reconstruct the lower spillway and join it to the upper spillway, that the canyon would be used if they were behind schedule. Also, that the RCC was to establish a competent foundation for the reinforced concrete spillway, to fill the plunge at the break, not to completely fill the canyon.
Then again, maybe I misunderstand the plan.
