The Manicouagan River is a river in Côte-Nord region of Quebec, Canada. The river originates at the Daniel-Johnson Dam of the Manicouagan Reservoir and flows approximately 200 kilometres (120 mi) south, emptying into the Saint Lawrence River near Baie-Comeau. Its headwaters are 560 kilometres (350 mi) from the mouth at the head of the Mouchalagane River.[1]

The river's name, often abbreviated to Manic, is believed to come from a Montagnais word meaning "where tree bark is found". However the Innu of Betsiamites call it Menukuanistuk Shipu, which means "river of the cup".[2]

History

Surveying the Manicouagan River at the first falls, 1919

At the end of August 1535, Jacques Cartier, while sailing south, noted the mouth of this large river but gave it no name. In June 1664, Jesuit Henri Nouvel(fr) was the first missionary to travel upstream of the "Grand Manikouaganistikou River that the French call rivière Noire because of its depth". The next year, he "returned to the mouth of the Manicoüagan in June." The river's spelling has remained fairly constant from then on.[2]

In the early 1950s, the Manicouagan River attracted Hydro-Québec's attention for hydro-electric development because of the deep and fast running waters. In 1956, a dam was built at the mouth of Lake Sainte-Anne to regulate the Toulnustouc River, the main left tributary that empties in the Manicouagan between the Manic-2 and Manic-3 dams. Four years later, the main construction work began on the dams and power stations of the Manicouagan River and its neighbor to the west, the Outardes River. By 1978, this project, with a total power supply 4672 MW, was completed.[2]

Hydro-electric dams

There are a number of hydroelectric power plants on the Manicouagan, part of the Manic-Outardes Project:[3]
