Here's something interesting that I read in the local company rag. It's not mentioned anywhere in any news or web site. They got the whole Canada-side pumped storage drained, and are doing extensive geotechnical investigation. Why is it ignored by the media? Why are they doing it?
This thing has a near-zero seismic capacity, which is ok if you don't believe in earthquakes. Are they secretly working on it because of Niagara Tunnel Contention #1:
The tunnel is useless without bumping up the pumped storage.
I know from the history of this thing, and from many earlier investigations that it is amazing that it stands up as it is, let alone trying to increase the capacity.
For our tame media I suggest a few tidbits for their headlines - "Nobody told us" "Clutching at geotechnical straws" "Can soupy walls hold more?" :)
