PRI conducted Fish Passage Culvert Inspections (FPCI) throughout their operating areas in the Skeena-Stikine Forest District from 1999 to 2006 as part of PIR's ongoing commitment to mainting and restore environmental values. The round metal culvert at Site 607 was a partial barrier to fish passage due to the water velocity through the non-embedded culvert at low flows. The measured velocity at moderate flows was 0.65 m/sec exceeding the burst swimming speed of juvenile salmonids less than 50 mm fork length. Ninety-five 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 8.4km of important upstrean habitat. This site received a Parker score of 45, ranking it as a high priority site for fish passage restoration.
