Today I stumbled upon a very interesting historical document in the clutter that is my office. It was written by a former Manager of Public Works in the City of Port Alberni in 1993, five years after he retired. It’s called City of Alberni Water Supply Systems 1890-1993. And Although Hole-in-the-Wall is not specifically mentioned dams upstream and downstream of it are. And three those dams are still there. The lowest one by the railway trestle is gone. I tried scanning the document into a PDF. But sadly my technical skills aren’t up to doing that. So here are 3 JPGs that I hope are legible.
