WOW! No words needed here and the guy riding the concrete bucket. OH my! And the concrete made with 6 inch rock. They didn't mess around!

To you Civil Engineers out there ... When the river backs up behind a new dam, where does all the topsoil, logs, leaves, branches, pinecones etc. go ??? Is that what is called "overburden"? I'm no Dam expert but it seems like there would be a few billion metric tons of slurry that would wash up against the backside of the Dam clogging the whole bit up.
