Biologists are going to great lengths to try and save a salmon run in danger of extinction. Before Shasta Dam was built, countless Winter-Run Chinook used to make the journey from the McCoud River to the ocean and back. They now must spawn in the Sacramento River below Keswick. Water is pumped from the bottom of Lake Shasta to try and keep temperatures low enough for the eggs to survive, but climate change is making that impossible. Grant funding is allowing California Fish and Game to launch a pilot program to reintroduce Chinook to the Upper McCloud. When hatchlings become juveniles and instinctively head downriver, they’ll be funneled by a boom and a net as the cold river water enters Lake Shasta. Then they’ll be trucked to the lower sac and swim to the sea from there. Once the system is fully tested, salmon will be introduced to begin the process. The salmon are sacred to the Winnemum Wintu, who lost most of their ancestral lands when the dam was built, and have been seeking a way to restore them for years.
