Special needs

Require streams with clean gravel, complex habitat, and cool temperatures for spawning and rearing. Require access for anadromous migration. Spring/Summer Run require cool, deep resting holes for holding over summer. Productive nearshore marine habitat that provides high-quality prey in sufficient quantity for rapid growth at time of ocean entry.

Limiting factors

Water quality. Alterations of hydrology and watershed function. Fish passage. Riparian condition. Marine survival.

Conservation actions

Maintain or restore aquatic and riparian habitat. Continue ongoing restoration efforts involving landowners, tribes, and agency partners (NOAA, NMFS, ODFW, OWEB). Manage for sustainable harvest.
