Gitanyow Fisheries Authority conducted Fish Passage Culvert Inspections (FPCI) throughout the Kitwanga River South watershed in Skeena-Stikine Forest Distict in 2007 as part of a watershed assessment. The elliptical metal culvert at Site 346 was a partial barrier to fish passage due to the water velocity through the non-embedded culvert at low flows. The measured velocity at relatively low flows was 1.57 m/sec, exceeding the burst swimming speed of juvenile salmonids. The GFA also felt that the veolcity in the culvert at high flows (23 cm high water mark) may be too high even for adult salmonids. Ninety-two percent of the stream is barred to juveniles. By restoring safe fish passage for all life stages of fish present in the stream, fish will gain access to approximately 4.7 km of important upstream habitat. This site received a Parker score of 42, ranking it as a high priority site for fish passage restoration.
