Number of salmon heading up B.C.’s Fraser and Chilcotin rivers has slowed since landslide, report says

Title: Salmon Migration Disrupted by Landslide on Chilcotin River, Threatening Reproduction Cycle
In a recent report shedding light on the aftermath of last month’s landslide into the Chilcotin River, concerns have arisen regarding the impact on the annual salmon migration. These salmon swim up the Chilcotin and Fraser rivers each year to reproduce, but their journey is currently facing obstacles.
Monitoring efforts indicate a slowdown in the number of salmon heading upstream during August, with uncertainty regarding the full extent of the disruption. Scott Hinch, a salmon ecologist at the University of British Columbia, highlighted the significant role the landslide played in impeding the migration, raising concerns about the fish’s ability to complete their journey to Chilko Lake.
Updates from the Pacific Salmon Commission revealed a stark contrast in expected salmon numbers, with only a fraction of sockeye salmon reaching upstream of the slide location. The landslide, which occurred near Farwell Canyon, has physically obstructed the salmon’s passage, while debris in the river could further hinder their navigation.
The Tŝilhqot’in National Government has issued a temporary halt on fishing the affected runs to prevent further harm to the Chilcotin River chinook and sockeye populations at risk of dying out. The Federal Department of Fisheries and Oceans has deployed monitoring tools upstream of the slide area, although no significant salmon migration has been observed yet.
Jeff Grout from the DFO emphasized that while this year’s sockeye run is expected to be smaller due to previous challenges faced by the salmon population, the fish have demonstrated resilience in overcoming obstacles in the past.
With approximately 117,000 sockeye expected to make the trek to Chilko Lake this summer, the full impact of the landslide on the salmon population will become clearer as more fish are anticipated to navigate through the disrupted river system in the coming weeks.
As researchers and officials track the evolving situation, the hope remains that these resilient salmon will manage to navigate the obstacles and ensure the continuation of their crucial reproduction cycle.
