The Mississagi River is a river in the Algoma District and Sudbury District in the Canadian province of Ontario . It has its origin in the Sudbury District and flows over a distance of 266 km to Lake Huron , into which it flows at Blind River in the Algoma District.
etymology
The river name is derived from the Ojibwe language - from misi-zaagi , literally translated as "river with a wide mouth".
Hydrology
The river drains an area of 9270 km². The mean discharge is 119 m³ / s. The months with the highest discharge are April and May with 210 and 209 m³ / s respectively.
history
The Ojibwa used the river as a transport route between the forests of inland Ontario and Lake Huron. In 1799 the North West Company built a fur trading post at the mouth of the river. This base was closed in 1900. In the second half of the 19th century, the river was used to transport logs to the sawmills at Blind River.
