The range of this species is generally along the lower Yellowstone, Missouri
and lower Mississippi rivers with historical documentation from 13 states. Sicklefin
chubs appear to prefer main channel sand/gravel areas of large, turbid and free-flowing
rivers. Little Knife Bay (Lake Sakakawea), the upper Missouri River and the
Yellowstone River are the only areas in North Dakota in which this species has
been collected in the past four decades.
