This small sucker (to 25 cm), along with the Nooksack dace, evolved in an isolated ice-free refuge in Washington State during the most recent glaciations. It occurs in small streams, sloughs, marshes and ponds in Washington and British Columbia's Fraser Valley. Salish suckers are nocturnal, spawn in riffles during spring, and eat a variety of insect larvae. Canadian populations are in decline and one is believed extirpated. Historically habitat loss and fragmentation to agricultural and urban development have been the main causes of decline. These forces continue to impact the species, although water quality degradation, decreased flows, and introduced predators are also concerns.
