Big Bar Landslide Incident

Fish wheel down stream of slide

In late June, a landslide was discovered at a very remote and narrow part of the Fraser River near Big Bar, north of Lillooet, British Columbia. Huge pieces of rock from the cliffs above created a five-metre waterfall in the river, preventing salmon from progressing upstream to their spawning grounds. This poses a very serious threat to key Fraser River salmon runs.

Within a week of discovering the blockage, a Unified Incident Management Team was established to lead ongoing response operations. The Unified Incident Management Team is comprised of First Nations, Federal, and Provincial governments. The incident response team is comprised of approximately 100 people who have deep scientific, technical and industry expertise. A First Nations Leadership Panel has also been formed to provide guidance and decision-making via consensus related to the incident.

The Unified Incident Management Team is working to evaluate and respond to the changing conditions that this dynamic situation presents. The team regularly engages with external experts to ensure all feasible options are assessed. Furthermore, no strategy is completely off-the-table and we continue to reevaluate new and past options. For more information view Big Bar Landslide daily response updates.
