Klamath and Trinity River tributaries

Spring-run were once a primary component of the Klamath Basin Chinook salmon population. However, per Goodman, populations are now at a fraction of historical levels in the Klamath River Basin with a hatchery supporting thousands of returns but natural areas composed of a couple of hundred fish as indicated by multi-agency dive surveys in the Klamath and Trinity River tributaries (seen here) in 2019.
