I’m not sure if this is going to work. If it does you should see a link to a FaceBook album of some photos of the dam under construction. I’m not sure if it’ll work if you are not a member of that FaceBook group. Hint: click on the link under “12 – Cod Beck Reservoir|22 Photos”.
I could look for hours at these old photographs. Trying to identify landmarks and features I know well or features that have now disappeared.
