In drought years and when marine heat waves warm the Pacific Ocean, late-migrating juvenile spring-run Chinook salmon of California’s Central Valley are the ultimate survivors. They are among the few salmon that survive in those difficult years and return to spawning rivers to keep their populations alive.
The Sacramento River system is home to the only winter-run Chinook salmon in the world. This unique population is cut off from its historical spawning and rearing habitat, and faces many other threats, but efforts are underway to help it recover.

Overlooking capacity of large females may lead to overharvest.
