The Klamath River’s outstandingly remarkable value is its anadromous fishery, featuring salmon and steelhead trout. The river supports several anadromous species during most of their in-river life stages. Species include Chinook salmon (spring- and fall-runs), coho salmon, steelhead trout (summer- and winter-runs), coastal cutthroat trout, green and white sturgeon and Pacific lamprey. The evolutionarily significant unit of coho salmon, the Southern Oregon/Northern California Coast coho, is federally listed as a threatened species under the Endangered Species Act. The Klamath River is designated critical habitat. The anadromous fishery supports the river’s sport fishing guide and resort industry, Native American subsistence and ceremonial culture and the ocean commercial and sport fishing industry.
