Fraser Landslides Research Project Webinar & Dialogue Session

In 2018, the Big Bar Slide event on the Fraser River created a blockage that significantly and negatively affected migrating salmon and cost millions of dollars in ongoing mitigation costs.

The impacts of another event, like the Big Bar Slide could be catastrophic. Migrating Fraser River salmon populations are at dangerously low numbers, and another significant slide blocking migration could spell disaster for these already stressed and vulnerable salmon populations.

Through a 3-year, BC Salmon Restoration and Innovation Fund(ed) project, “Landslide impact on flow dynamics, fish migration and genetics of Fraser River salmon”, analysis of past slide dynamics were used to develop a predictive model of potential future slide activity, and we now have an opportunity with the data to inform potential future slide response and possibly mitigate impacts to salmon migration. Key research findings include:

• 13 sites of concern identified where a new landslide could have a significant impact on salmon migration success.
• Several locations identified as current barriers to adult salmon migration under high flow conditions.
• 279 landslide events identified in the Fraser River corridor since the last glacial retreat.

There is a strong need for continued education and collaboration to determine the next steps in addressing the risk of landslides in the Fraser River Canyon.

On November 27th, the project team members will hold an online ‘Fraser Landslides and Impact on Salmon: Webinar and Dialogue Session’. Participants will learn about the research method and findings, hear about the project’s engagement process, and discuss future opportunities and participant involvement in next steps.

After registering, you will receive a confirmation email containing information about joining the meeting.

Thanks to the Pacific Salmon Foundation of British Columbia for sponsoring this important webinar and dialogue session.
