The coho salmon population in the Elwha River is considered relatively healthy. They are of mixed origin, from both wild and hatchery stock. Restoration of coho focuses on increasing the number of fish at all stages of their life cycle.
The current hatchery program for Elwha coho salmon is operated by the Lower Elwha Klallam Tribe as a harvest augmentation for commercial and recreational fishing. The annual release goal is 750,000 yearling smolts.
A summary of the Elwha River coho salmon restoration strategies includes:
- Release of smolts from hatchery
- Natural spawning of adults
- Planting of fertilized eggs
- Distribution of fry and smolts in various upstream locations
