Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Coastal and mountain streams of Arctic, Pacific, and Missouri River drainages from extreme southern Yukon in Canada to headwaters of Columbia River drainage in northern Nevada, USA, and McCloud River drainage in northern California, USA.

Biology     Glossary (e.g. epibenthic)

Occurs in deep pools of large cold rivers and lakes (Ref. 5723). Most common in high mountainous areas where snowfields and glaciers are present (Ref. 5723). Rarely anadromous (Ref. 5723, Ref. 51243). Lacustrine form matures in lakes and spawns in tributaries, where young reside for one to three years (Ref. 10367).
