Dam Noise
To/From: REDACTED
What's that sound coming from under the dam? Did you guys start up some new machinery I'm not aware of?
We don't know. It's halfway between us and we only hear it at random intervals.
What do you mean "we don't know?" This could be a structural concern.
Yeah. Maybe. Look, I don't really want to talk about it over e-mail. I'll come up to your office.
