Abstract: In 1996, the Courtney Fish and Game Protective Association constructed 2 wooden weirs and 1 rock weir in a channelized portion of Arden Creek, Vancouver Island, B.C. The Association added an additional wooden weir in 1997. Volunteers from the Association, students from Puntledge Park and Lake Trail schools, and Urban Salmon Habitat Program staff conducted fish assessments at weir (treated) and control (untreated) sites in 1996 and 1997. We found more fish at treated sites in both years. In 1996, 66% of the fish sampled were associated with weirs, and in 1997, 80%. The density of fish at treated sites was 0.67 fish/m2, compared to 0.35 fish/m2 at control sites in 1996, and 0.29 fish/m2 at treated sites compared to 0.07 fish/m2 at control sites in 1997. We estimated the biomass to be 3.32 g/m2 at treated sites and 2.4 g/m2 at control sites in 1996. In 1997, we estimated the biomass at 3.87 g/m2 at treated sites and 0.35g/m2 at control sites...
