Global Range: (20,000-200,000 square km (about 8000-80,000 square miles)) Range includes the Coast, Cascade, Rocky, and Sierra Mountains northward as far as Yukon and British Columbia (Stewart and Oswood, 2006).

Habitat Type: Freshwater

Comments: It is common in creeks and rivers (Gaufin et al., 1972).

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Estimated Number of Occurrences: 81 - 300

Comments: Gaufin et al. (1972) cite Montana distribution as Broadwater, Cascade, Flathead, Gallatin, Granite, Jefferson, Madison, Mineral, Missoula, Park, Powell, Ravalli, Stillwater, and Sweet Grass Cos. Newell et al. (2006) report it from Glacier National Park and the Flathead River basin in western Montana. It has been documented in the Ohanapecosh region in Mount Rainier National Park, Washington (Kondratieff and Lechleitner, 2002). Call and Baumann (2002) cite southern Utah distribution as only Huntington Creek in Emery Co. (Wasatch Plateau).

Adults emerge from February into July (Gaufin et al., 1972).
