Range DescriptionFound only in the eastern Pacific, from Monterey Bay, California, to Nushagak River and Pribilof Islands, Bering Sea, Alaska (Lee et al. 1980, Page and Burr 1991). Distribution coincides closely with coastal temperate rainforest, although there may not be a functional linkage (Hay and McCarter 2000). Historically spawned in the Sacramento River system and farther south along the California and Baja California coast but have been extirpated from those locations, occurring now only as far south as Monterey Bay (one record from this location) and in the Klamath River in California, rivers in Oregon and the Columbia River in Washington (Hay and McCarter 2000, Mecklenburg et al. 2002, Willson et al. 2003). In Alaska, seasonally abundant in most major drainages from Southeast Alaska west to Cook Inlet and become less abundant westward toward the Aleutian Islands and the Pribilof Islands in the Bering Sea (Fritz et al. 1993, Willson et al. 2003).
