Three subspecies of cutthroat trout are found in Washington. The coastal and westslope are native to Washington, while the Lahontan cutthroat is native to the Great Basin of California, Oregon, and western Nevada, and is the largest of the cutthroat subspecies.
Among coastal cutthroat trout, some populations around the Salish Sea (including Puget Sound), Washington Coast and lower Columbia River tributaries are anadromous.
