    This is the town of Klamath (pop. ), a community predicated on Chinook salmon and steelhead trout. Above Klamath, the river loops between high bluffs thick with young redwoods and madrones.   The pre-season numbers unveiled by Dr. Michael O’Farrell of the National Marine Fisheries Service estimate only , Sacramento River fall .

    The Klamath River is one of only three rivers that bisect the Cascade Mountain Range. Beginning in Oregon's high desert interior, it cuts through the Cascades and the Klamath Mountains before entering the Pacific Ocean in northern California. This creates a wide diversity of habitats supporting an abundance of fish and wildlife.   Klamath Riversport anglers have nearly reached the 3, quota of adult fall-run Chinook salmon, triggering a size restriction on the lower river on Thursday, Sept. As of Thursday, anglers along the river’s lower 40 miles may no longer keep adult fall-run Chinook that are 22 .

It is estimated that Klamath River migrations of fall- and spring-run Chinook salmon have been reduced by over 90 percent from those in the early twentieth century Managers have attributed the losses to hydraulicFile Size: KB.The Klamath River fish kill occurred on the Klamath River in California in September According to the official estimate of mortality, ab fish died.

Though some counts may estimate o adult chinook salmon (Oncorhynchus tshawytscha) were killed when returning to the river to spawn, making it the largest salmon kill in the history of the Western United States. The Klamath River tribes—the Yurok, Hupa, Shasta, and Karuk—harvested salmon by raising weirs across the river for ten-day periods that were coordinated with sacred Fixing the World ceremonies.

This fishing method provided abundant salmon for all the tribes while leaving enough spawners in the river to produce the runs in future years.
