Sacramento River Winter-Run Chinook Salmon

Oncorhynchus tshawytscha

LEVEL OF CONCERN: CRITICAL
Sacramento River winter-run Chinook salmon (winter-run) face immediate risk of extinction. The ESU has been extirpated from its native spawning range by dams and has been reduced to a single small spawning population, which is wholly dependent on artificially-created spawning habitat and cold water releases from Shasta Reservoir.
