Comments: Tends to inhabit strong currents around or under stones (Ref. 31730).  Occurs in streams with swift water in hilly, sub-alpine areas.  Preys on benthic invertebrates.  Spawns in areas with fast-flowing water on gravel bottom.  Still commonly found in suitable habitats, but number of spawning grounds has decline sharply (Ref. 59043).
