Big Bar Landslide Incident

In response to a significant landslide discovered between June 21 and 23, 2019 in a narrow portion of the Fraser River near Big Bar, just north of Lillooet, B.C., a unified command incident management team has been established. 

Officials learned of the Big Bar Landslide in late June. After examining satellite imagery, data indicates the slide may have occurred in late October or early November.

The unified command incident management team is comprised of individuals from the Government of British Columbia, the Government of Canada, and First Nations. A First Nations Leadership Panel has also been formed to provide guidance and decision-making via consensus related to the incident. Together, the incident management team is working to mitigate the landslide and its effects on salmon migration.  For more information view Big Bar Landslide daily response updates.
