A massive marine heatwave warmed the eastern Pacific Ocean through much of 2025, but the wind-driven upwelling of cold, nutrient-rich water that drives the rich marine productivity of the West Coast kept the ecosystem healthy.
California’s Wildlife Conservation Board approved $59,642,096 in grants for 27 projects across 18 counties to protect biodiversity, restore important wildlife habitats and improve public access to nature.
Mainstem Columbia River basin water supply forecasts remained mostly steady or rose just slightly over the last month, with the March forecast at The Dalles Dam at 95 percent of the 30-year average, up 2 percentage points from February.
The Bureau of Reclamation has launched a new three-phase prize challenge to identify innovative solutions that prevent the spread of aquatic invasive species through watercraft ballast compartments.
A massive marine heatwave has dominated waters off the West Coast since last summer. This marks only the third time on record that such a large section of the coastal ocean has remained so warm for so long—particularly into winter months—without it being an El Niño, NOAA scientists report.
Researchers spent five years developing an AI-based model to protect freshwater fish worldwide from extinction, with a particular focus on identifying threats to fish before they become endangered.
A $1 million federal investment will jump-start critical engineering and design work on fish passage and alternative solutions at Oregon’s McKay Creek Reservoir Dam, laying the technical groundwork to eventually reconnect more than 100 miles of historic salmon and steelhead habitat.
