Thanks for filling me in on the concrete. No pun intended...
I don’t like that they’re going to remove and replace portions of the upper chute. I mean, for this year, maybe they can get by if it’s not suffered from the recent past releases, but in the long run, it ought to get replaced also. Maybe next year or 2019.
Note the RCC buttress for the ogee weir emergency spill way. Wonder if they got scared it may tip over?
