Once tremendously abundant, California wild salmon are now on the brink of extinction

The State of Salmon in California

Chinook, coho and steelhead were once tremendously abundant in most of California’s major rivers and streams. As recently as the 1960s, salmon and steelhead were so plentiful in streams that horses would get spooked trying to cross.

Due to water damming and diversions, habitat degradation, climate change and drought, salmon and steelhead populations have declined dramatically. They have even completely disappeared from many streams.

But there is hope. Wildlife and river restoration groups throughout the state are working together to change this trajectory.

The State of Salmon in California presents the problems salmon are facing and their population trends in the state’s major rivers and streams, as well as the transformative solutions that could bring these species back from the edge.

Restoration From Headwaters to the Sea

Coho salmon, Chinook salmon and steelhead depend on all aspects of stream health during their lifecycle. From watershed headwaters to river’s mouth, salmon and steelhead rely on stream well-being for survival and reproduction.
