Tŝilhqot’in Nation Takes Action to Save Chilko Salmon from Catastrophic Risk

Today, the Tŝilhqot’in National Government (TNG) announced its commitment to protect Chilko salmon runs by advancing – and funding – urgent mitigation measures to prevent imminent rockfall at Nagwentled (Farwell Canyon) on the Tŝilhqox (Chilcotin River), a critical corridor for Fraser River salmon migration.

TNG leads the Emergency Salmon Task Force, established in response to the Tŝilhqox Landslide in 2024. TNG raised the alarm when a geotechnical report commissioned by BC after the landslide found an “imminent risk” of rockfall into the Tŝilhqox at Nagwentled, the gateway for several critical salmon species to return to their spawning grounds. The Task Force has warned that further rockslides during the salmon migration period could be catastrophic and long-lasting, creating migration delays similar to the 2019 Big Bar landslide, with devastating impacts on already threatened salmon populations.

Nagwentled is a critical migration corridor for salmon stocks of local, regional, and international importance. This includes the iconic Chilko sockeye run, which regularly accounts for more than half of the total Fraser River sockeye return and plays a vital role for all First Nations along the Fraser River and marine approach fisheries including Vancouver Island, Canadian commercial fisheries, and southern US commercial and subsistence fisheries, making the consequences of disrupted passage at Nagwentled far-reaching and international in scale.

Facing this imminent risk, the Task Force has developed a proactive slope stabilization plan that includes manual scaling and targeted trim blasting – a well established and common approach for stabilizing slopes for infrastructure projects. This plan was collaboratively designed, assessed and supported for urgent action by all Task Force partners, which include technical representatives of TNG, BC and the federal Department of Fisheries and Oceans (DFO) and the Upper Fraser Fisheries Conservation Alliance.

However, the Tŝilhqot’in Nation was alarmed by recent indications from both Canada and BC that funding will not be made available to support this proactive mitigation plan before the 2026 migration, putting these critical salmon populations at dire risk.

In response, TNG is announcing its commitment to fund this mitigation work itself, if government will not step up to prevent this potential catastrophe, rather than risk devastating impacts for salmon runs that the Tŝilhqot’in have protected and stewarded for generations. Costs are estimated at $2.5M – $3M (in contrast to more than $200M spent by DFO in response to the Big Bar Slide).

TNG has proactively engaged provincial and federal authorities to initiate permitting and is fully committed to consulting all impacted First Nations along the Fraser River who depend on these salmon for their sustenance and way of life.
