As the coho salmon pass through these waters, many will show symptoms of lethargy, loss of equilibrium and disorientation and die within a few hours of showing these symptoms.
Rigorous effectiveness monitoring has not been performed, but a few dozen coho and chum salmon are known to spawn there annually in a sustaining population.
Among the thirty-four natural and experimental secondary hosts found in scientific literature are the coastal cutthroat trout, rainbow trout, coho salmon, chum salmon, and kokanee salmon.
