Wild salmon have splashed their way up the Klamath River and its tributaries — including the largest of those tributaries, the Trinity River — for at least 12,000 years. Owing to a geological peculiarity, the Klamath Basin was a refuge for countless forms of wildlife at the time. Located just south of the glacial formations that covered much of the western hemisphere’s lands, but just west of the volcanoes that rendered much of Northern California uninhabitable, the Klamath hosted an enormous diversity of wildlife that eventually spread across much of the American West.
Nowadays, the Klamath-Trinity have an altogether bleaker distinction: They are California’s greatest remain refuge for wild salmon. During the Arcadian time that endured prior to Euro-American arrival, the salmon lashed rivers into whiteness throughout Northern and Central California. People could walk across rivers on the back of the migrating fish. Now, the Klamath-Trinity — which courses through the wildest corners of California and Southern Oregon — stands as the only river system in the Golden State where runs of non-hatchery salmon still return most years by the tens of thousands.
