Fish Passage

Road stream crossings on fish streams can be barriers to movement of juvenile and adult fish. Free movement of all life stages of fish is important as it allows access to the appropriate habitats for rearing and spawning. The greatest numbers of fish passage problems in British Columbia that have been identified are associated with closed bottom structures (culverts).

The federal and provincial government, along with the forest industry, developed the following guidance document to help plan, prescribe and implement sound fish-stream crossing practices associated with road infrastructure in B.C. The Fish-Stream Crossing Guidebook is intended to improve fish passage outcomes at new crossings and restorations. 

 Strategic Approach

Government has developed a strategic approach for remediating barriers to fish passage, from initial assessments of crossings, to the final design and installation of new structures. Improving fish passage involves determining highest priority watersheds and within those watersheds, setting priorities for restoration.
