Other Status
LT - LT: Listed threatened - 2005-06-28 - NMFS (1995) did not identify on the southwest Washington coast any native populations of coho salmon that would qualify for protection under the Endangered Species Act. However, NMFS did not exclude the possibility that some native late-run coho salmon occur in the Chehalais River basin. NMFS (Federal Register, 3 November 2000) acknowledged receipt of a petition to list the lower Columbia River populations of coho salmon on an emergency basis and to designate critical habitat. NMFS determined that the petition contained substantial information

Global Range
The Lower Columbia River coho ESU includes all naturally spawned populations of coho salmon in the Columbia River and its tributaries from the mouth of the Columbia up to and including the Big White Salmon and Hood Rivers, and includes the Willamette River to Willamette Falls, Oregon. Twenty-five artificial propagation programs also are considered to be part of the ESU (NMFS 2005). Compared to adjacent ESUs, oceanic records are more frequently from Washington waters and less often from Oregon and British Columbia (National Marine Fisheries Service 1995).
