Warm It Up: Balancing the Needs of Sturgeon, Salmon, and Humans
The historic Sacramento River once flowed unobstructed from rocky Sierra Nevada headwaters to expansive Delta wetlands, providing a diversity of interconnected aquatic habitats. Fish species evolved Read More…
Flashback Friday: Winter-Run Salmon and Temperature
In today's Flashback Friday, we explore the delicate dance required to keep water cool enough for winter-run Chinook salmon in the Sacramento River. These endangered fish are Read More…
Hot and Cold: Dialing in on Temperatures for Winter-Run Salmon
Of the four runs of Chinook salmon that inhabit the Central Valley, winter-run historically had the most daunting journey to reach their spawning grounds. These cold-loving fish Read More…
Stay Cool, Babies – Growth and Temperature Tradeoffs for Juvenile Chinook
Although they spend their lives hidden beneath the surface, fish are directly affected by the weather happening outside their aquatic world. This is particularly true of species Read More…
Winter-Run Salmon and the Delicate Dance of Temperature
Winter-run Chinook salmon (Oncorhynchus tshawytscha) are the most endangered of California’s four salmon runs. These salmon return to freshwater in the winter, and historically sought refuge in Read More…
