In the Gulf rivers it occurs from central Texas to the Yellow River of Florida. In the St. Lawrence it is absent from Lake Superior and its drainages. Its northern range includes the Red River of the North, Winnipeg River and Nelson River.
In Michigan this species is found mainly in rivers in the lower peninsula from the Saginaw and Grand drainages south. However, there are also records from the Sturgeon River in the upper peninsula.
