Designation of Critical Habitat for Snake River Spring/Summer Chinook Salmon


Endangered Species Act
Action Status
Final Rule
Affected Species


Through this rule, NMFS revises critical habitat for Snake River spring/summer chinook salmon (Oncorhynchus tshawytscha), pursuant to the Endangered Species Act (ESA) of 1973. After a review of the best available scientific information, NMFS determines that Napias Creek Falls constitutes a naturally impassable barrier for Snake River spring/summer chinook salmon. NMFS, therefore, excludes areas above Napias Creek Falls from designated critical habitat for this species.
