    Fish Passage Assessments

Series: Forest Investment Account (FIA) - Land Base Investment Program
Description:
Forsite Consultants Ltd. is currently working on a fish passage assessment project within the Mid-Coast TSA. This project is focusing on high value fisheries watersheds, as identified by the provincial government, including the Bella Coola, Sheemahant, Machmell, Kilbella, and Chuckwalla Rivers. The intention of this work is to assess culverts located within these watersheds that may be acting as barriers to fish passage. In order to identify potential structures to be assessed we conducted a GIS analysis where known fish presence information, as documented in the provincial Fisheries Information Summary System (FISS) and other databases, was overlayed upon the road networks associated with each of the river systems outlined above. We also included suspected fish streams where no known information was available (using slope threshold values which are species specific 20-30%). We also used road data provided by International Forest products to aid in sampling of priority road networks.
