Southwest and Olympic Region Fish Passage Culvert Projects

As a member of a design team, NW Fish Passage performed geomorphic assessments for four culverts, three in the Southwest Region and one in the Olympic Region. We prepared the Watershed and Site Assessment of the Preliminary Hydraulic Design Reports. We worked closely with the design team to ensure fish passage is achieved. NW Fish Passage provided information on grain size, determining the representative reference reach, and calculating the vertical and horizontal channel profile.
