Upper Klamath-Trinity Rivers Fall-Run Chinook Salmon

Oncorhynchus tshawytscha

LEVEL OF CONCERN: MODERATE
Upper Klamath-Trinity Rivers (UKTR) fall-run Chinook are not in immediate danger of extinction, although  their numbers have declined in recent decades. There appears to be an increasing reliance on hatcheries to maintain fisheries, and returns of hatchery-origin fish may be masking a decline of wild production in the Klamath-Trinity Basin.

How are wild UKTR fall-run Chinook doing?
