Fisheries biologists this week downgraded two Columbia River fish return forecasts, dropping the fall Chinook forecast 9 percent and also predicting a return of A- and B-Index summer steelhead that would be the worst return of the fish since Bonneville Dam was built in 1938.
Less than two years ago, four dams on the Klamath River were removed. This week, the first peer-reviewed science is out — published in Scientific Reports– confirming that Chinook salmon reoccupied 88% of their historical range within just two migratory seasons. Chinook salmon didn’t just trickle back into reconnected habitat in the upper Klamath Basin….
Water birds in the Columbia River basin consume large numbers of out-migrating juvenile salmon and steelhead every year. Three government management plans targeting four avian predator breeding colonies have met with mixed results, according to a recent report by Northwest experts.
The tributary of the Scott River in Northern California’s Klamath Basin once supported coho salmon, but as it diminished, so did they.
The Washington Department of Fish and Wildlife, in coordination with the Cowlitz Indian Tribe, U.S. Forest Service, and conservation partners, have reintroduced spring Chinook salmon into the upper North Fork Toutle River watershed within the Mount St. Helens National Volcanic Monument for the first time since the 1980 volcanic eruption. In June, WDFW and project…

The Washington Department of Ecology has issued an administrative notice to Nippon Dynawave Packaging documenting environmental violations stemming from the May 26 storage tank failure at the pulp and paper mill at Longview. The tank collapse released 900,000 gallons of highly caustic white liquor that flooded the industrial site and led to the deaths of […]
