The Nipigon River is located in Thunder Bay District
in Northwestern Ontario, Canada. The river is about 30 miles long when
measured to the head of Ombabika River and 160 to 660 feet wide. It
flows from Lake Nipigon to Nipigon Bay on Lake Superior at the community
of Red Rock, dropping from an elevation of 853 to 600 feet. It is the
largest tributary of Lake Superior.
Since 1943, 5,545 square miles of the Ogoki River basin has been diverted
to the headwaters of the Little Jackfish River, a tributary of Lake
Nipigon. This diversion increases the size of the river's watershed
by almost 15,350 square miles, and contributes an average of about 4,100
cubic feet to the Nipigon River. This increased flow has caused significant
erosion and landslides along the river. |
