The Kaministiquia River is a river in the Canadian province of Ontario .

It has its origin in Dog Lake , a 55 km² large lake 40 km northwest of the city of Thunder Bay , the discharge of which is regulated. The Dog River is the main tributary of the Dog Lake .

The Kaministiquia River covers the first kilometers in Silver Falls Provincial Park . It flows south through Little Dog Lake . At Kaministiquia , the Kaministiquia River takes in the right tributary Matawin River . Further south, about 30 km west of Thunder Bay, it passes the 40 m high Kakabeka Falls waterfalls. It then turns to the east, takes on the Whitefish River , flows about 30 km further in an easterly direction and flows south of Thunder Bay into the Lake Superior .

The name of the river is derived from the language of the Ojibwe Indians and means "with islands", which refers to the two large islands that are located in the mouth of the river. The inhabitants of this area also call the river Kam for short . The estuary forms a large river delta that divides into three river arms. The southern one is called Mission River , the middle arm McKellar River and the northern one just Kaministiquia . These arms of the river were expanded in the early 20th century to allow navigation on the river.


Similar to the Pigeon River , the Kaministiquia also played a major role in the development of western Canada. During French rule, trading posts were established in 1679 and 1717 to enable the fur trade . The Canadian painter Paul Kane , who traveled to the west of Canada in the first half of the 19th century to capture the life of the Indians in his sketches, still used this river for his expeditions. After 1883 the course of the Kaministiquia River was used to lay railways here by the Canadian Pacific Railway .

Use of hydropower

Ontario Power Generation operates two large hydropower plants on the Kaministiquia River. The Kakabeka hydropower plant was built in 1906–1914. The 4 turbines together provide 25 MW .

The Silver Falls hydropower plant, completed in 1959, has an output of 48 MW. It uses Dog Lake as a reservoir and takes advantage of the gradient between Dog Lake and Little Dog Lake.
