Global Range:

H - >2,500,000 square km (greater than 1,000,000 square miles) - H - This species ranges very widely, occurring farther north in Canada than any other crayfish species. Its native range extends as far north as the southern tip of Hudson Bay; southward it occurs from New England to western Montana and through the Missouri, Mississippi and Ohio River basins to Oklahoma and northern Arkansas; and it has also been widely introduced outside its native range (Pflieger, 1996). Recently it was discovered in the United Kingdom for the first time in the River Lee system of North London (Ahern et al., 2008).
