Fish population trends in the Pacific Northwest and Yukon River regions show varying results for salmon and steelhead species. In the Yukon River, Chinook Salmon returns for the 2026 season have exceeded initial estimates. The Department of Fisheries and Oceans revised its projection to approximately 30,000 fish crossing into Canadian waters, up from an original expectation of 18,000. While recent counts at the Whitehorse fish ladder show a seasonal increase, experts caution that these smaller runs may represent a ‘new normal’ compared to historical levels. The population remains below the rebuilding target of 71,000 fish. In the Columbia River basin, fall Chinook runs at the Bonneville and Lower Granite dams are trending ahead of the 10-year pace, but steelhead numbers remain significantly low. In the Snake River, managers expect a return of approximately 21,000 hatchery fall Chinook but only about 5,000 wild fish. In Canada, sockeye salmon returns on the Fraser River have fallen significantly below expectations. While pre-season forecasts predicted a mid-point return of approximately 7.74 million fish, real-time data indicates an abundance of less than 2.8 million. Fisheries and Oceans Canada (DFO) attributed this decline to environmental factors such as wildfires, drought, low snowpack, and El Nino conditions. Consequently, recreational and commercial openings are highly unlikely for the 2026 season, with priority given to First Nations food, social, and ceremonial needs. DFO noted that fisheries may resume later in the season if abundance levels increase above specific thresholds. Regulatory responses continue to address abundance concerns.
