Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
North America: Pacific Slope drainages from Snohomish River and Puget Sound in Washington to Rogue River system in Oregon and California, USA.
Inhabits rubble and gravel-bottomed pools and riffles of headwaters, creeks and small rivers. Where the Cottus rhotheus and C. aleuticus do not occur, this species occupies riffles ; at localities where all occur together, it shifts to pools.

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01097 (-0.17964 - 0.20159), b=3.03 (2.92 - 3.13), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=432).
Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100) .
