Global Range: (20,000-2,500,000 square km (about 8000-1,000,000 square miles)) Range is uncertain; includes Lake Nipigon and adjacent lakes in Ontario, and Lake Saganaga in Minnesota and Ontario, and possibly other lakes in south-central Canada (Page and Burr 2011). Along the Minnesota-Ontario border, Etnier and Skelton (2003) found what they referred to as C. nipigon in Lake Saganaga and Lake Saganagons. They cited previous reports of C. nipigon from Lake Winnipeg, Manitoba, and Lake Abitibi and Lac Seul, Ontario. They also noted that Clarke (1973) suggested, based on rather small samples, that a form with gill-raker counts similar to those of C. nipigon also occurs in Little Athapapuskow Lake and Mink Narrows, both located north of the Manitoba Great Lakes near the Saskatchewan border.
