Salmon are also indicators of healthy river and marine ecosystems — as habitats degrade and disappear, so do salmon, and as salmon disappear, the quality of the ecosystem decreases as well, since salmon are an important source of nutrients. Damming of rivers has caused the collapse and extirpation of many salmon runs throughout the west.
The river supported species including chinook salmon, coho salmon, and sockeye salmon, as well as steelhead, white sturgeon, and Pacific lamprey.
