North River Consulting Ltd. performed 787 fish passage culvert inspections in the Willow, Tabor and Bowron watersheds from July to November, 2014. A large number of the office based mapped crossings did not exist, many were already deactivated, and the rest were inaccessible due to the washouts, and heavily brushed in roads. The results of the assessments in the Willow watershed found that for closed bottom culverts (302 sites) 69% of sites were barriers, 28% potential barriers, and 3% were passable. The results of the Tabor watershed assessments found that for closed bottom culverts (214 sites) 55% of sites were barriers, 36% potential barriers, and 9% were passable. The results of the assessments in the Bowron watershed found that for closed bottom culverts (74 sites) 78% of sites were barriers, 16% potential barriers, and 6% were passable. In total, 182 high/medium value habitat closed bottom crossing sites were found to be barriers. Of the high/medium value habitat sites in which closed bottom culverts were classified as barriers to fish passage, 15 priority sites (5 in each watershed) are recommended for immediate replacement or removal, with priority given to sites with high to medium value habitat, greater than 2m width streams, a high habitat gain index, and confirmed fish presence. In addition to the 15 identified priority removal sites, there are 167 remaining high/moderate value habitat closed bottom culvert sites that are classified as barriers or partial barriers which should be considered for future replacement/removal.
