Salmon Habitat Enhancement

This image shows a portion of the existing 12' penstock where a new branch was tied in to support a fish ladder, reopening upstream habitat to spawning salmon. The original penstock was scanned after concrete removal where the new section was to connect. The scan data allowed accurate design and pre-fabrication of the new piece, reducing costly field fit up requirements.
