Salmon Habitat Enhancement
This image shows a portion of the existing 12' penstock where a new branch will tie in to support a fish ladder, reopening upstream habitat to spawning salmon. The existing penstock was scanned after concrete removal where the new section will connect. The scan data allows accurate design and pre-fabrication of the new piece, reducing costly field fit up requirements.
The original penstock (partially exposed) and surrounding area.
A closer view of the penstock showing the complex miters at the tie in location. Welds and reinforcing rings shown in orange and yellow.
