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.
Upper Klamath-Trinity Rivers fall-run Chinook salmon abundance has varied widely throughout the Klamath Basin over the last decade, though the proportion of wild adults in the Trinity River has increased over that time.
