proposed and candidate species likely to be found in the White Salmon River are listed
below.
Snake River Sockeye Salmon
Although the ESA listing status came under review, the listing as endangered was retained in
the final listing. Migrating adults and juveniles are expected to use the lower White Salmon
River for thermal refuge. Sockeye salmon are the Oncorhynchus species most vulnerable to
elevated water temperatures and are most dependent on thermal refuge sites along their
migratory corridors for survival.
Snake River Spring/Summer-Run Chinook Salmon
Although the ESA listing status came under review, the listing as threatened was retained in
the final listing. Migrating adults and juveniles are expected to use the lower White Salmon
River for thermal refuge.
Snake River Fall-Run Chinook Salmon
Although the ESA listing status came under review, the listing as threatened was retained in
the final listing.
