Require streams with clean gravel, complex habitat, and cool temperatures for spawning and rearing. Require access for anadromous migration. 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.
Data gaps
Continued monitoring of recolonization of Upper Klamath River and Basin following restored fish passage in 2024. Evaluation of thermal regimes in Upper Klamath Basin and evaluation of spawning success in newly accessed habitats. Evaluation of outmigration patterns and predation on juvenile salmon. Mechanisms affecting marine survival and spatial, temporal utilization of nearshore marine waters.
Conservation actions
Maintain and restore aquatic and riparian habitat in Upper Klamath Basin to facilitate expansion of recolonizing salmon following restored fish passage in 2024. Identify and address any fish passage issues at Keno Dam and Link River Dam. Identify and address any screening needs in the Upper Klamath Basin that impact salmon.
