Inhabits a wide range of habitats, from rocky pools and riffles of headwaters to large lakes. Usually occurs in small, clear, cool creeks and small to medium rivers. May be found at a depth greater than 45 m (Ref. 1998). Moves to shallower water near sunrise and sunset to feed. Fry (1.2 cm in length) feed on plankton and other small invertebrates; bottom feeding commences upon reaching a length of 1.6-1.8 cm. Preyed upon by birds, fishes, lamprey, and mammals (Ref. 1998).
