Lol....
My brother was an electrical engineer on the three Columbia dams. I remember him telling me that one got poured ....backwards. That is....mirror image. Big snafu. I imagine a lot of drillin’, fillin, and whatelse was needed to wire and plumb it. I’m just guessin’.....but I’d say it’s the prime suspect for going boink. Wonder if that little error ever got out of the office trailor??
Or was that Snake River?? D’oh!
NEVER live downhill from any damn(for the ELF’s) dam. Or too close to any riverbank either.
