LEVEL OF CONCERN: CRITICAL
Central Valley (CV) spring-run Chinook are vulnerable to extinction in the next 50 years or less if present trends continue. Small, self-sustaining populations remain in only a few watersheds.
Populations of Central Valley spring-run Chinook plummeted during the drought (2012-2016), primarily as a result of high pre-spawn mortality of over-summering adults and eggs associated with reduced streamflows and high water temperatures. Straying of salmon from the Feather River Fish Hatchery to other watersheds, and hybridization with other populations, reducing the resilience of remaining natural-origin populations.
