Found in streams. Believed to be originally an inhabitant of lakes entering streams to spawn, then returning to lake. Habitat modifications and water abstraction have interrupted the lower course of most streams and distribution is confined to headwaters, possibly to two streams only. Spawns in November (Ref. 59043).
