| Oregon Coast | |||||
| Coho salmon | not present or severely depressed | declining | |||
| in lower mainstem, depressed | |||||
| wild coho in mid and upper reaches, | |||||
| heavily influenced by hatchery fish | |||||
| ESA Listing: Threatened | |||||
| High conservation significance | |||||
| due to worse conditions in basins | |||||
| to the north and south | |||||
| Chum salmon | possible heavy predation by hatchery | possibly declining | |||
| coho, low recovery rates since the | |||||
| 1950's, poor ocean productivity | |||||
| conditions may be contributing | |||||
