Hopefully "lessons will be learned" and dam designs include means of
drainage for maintenance or emergency. A bloody big tap at the bottom?

This dam was last drained in order to maintain that very facility. The
question is: why aren't they using it?

Or perhaps it is being used and the civilians writing in the press
haven't noticed.
