Adults inhabis lake margins; backwaters, rocky riffles and sand or silt runs of creeks and small to medium rivers. They probably feed on algae and bottom invertebrates (Ref. 1998). Preyed upon by birds and mammals; young may be preyed upon by some salmonids (Ref. 1998). Spawning in British Columbia probably occurs late spring (Ref. 1998). Edible but not currently eaten (Ref. 1998).
