A hundred years ago, a million adult chum salmon would return each autumn to spawn in tributaries and creeks along the Columbia River. But, like other varieties of salmon, overfishing, dams and loss of habitat decimated their numbers in Oregon and Washington. Columbia River chum salmon were listed as threatened nearly 25 years ago under the Endangered Species Act.  

A team of biologists at the Oregon Department of Fish and Wildlife has been leading efforts to reintroduce chum salmon in the Columbia River basin. They include operating a hatchery near Astoria, relocating returning adults and juvenile fry to historic spawning sites and tracking their movement using DNA sampling in waterways. Kelcee Smith is the chum salmon reintroduction coordinator at the Oregon Department of Fish and Wildlife. The Astorian recently profiled her work and partnerships with nonprofits and landowners to recover chum salmon. Smith joins us to talk about those recovery efforts and the threats the fish face today, including climate change.
