Restoring connectivity on tributaries throughout Western NL; addressing hanging culverts
In 2019/20 ACAP Humber Arm was contracted by Fisheries and Oceans Canada to survey Atlantic salmon rivers and their tributaries throughout the Bay of Islands and Humber River watershed (Humber River and tributaries, Hughes Brook and tributaries, Goose Arm River, Serpentine River, Cooks Brook) with a specific focus on culverts. All culverts observed were photo-documented and georeferenced. Culverts that could pose an obstruction to fish passage (collapsed, hanging, etc.) were surveyed in greater detail, with length, slope, drop, etc recorded. This data is currently being analysed.
The project will use data acquired through the 2019/20 surveys to identify hanging culverts that disrupt the connectivity of the river system. Using a weighted matrix that considers the culvert drop, area of upstream habitat to be made assessible, etc. culverts will be prioritized for the installation of 20 chutes to facilitate the passage for Atlantic salmon and other species.
