Manicouagan, RéservoirRéservoir Manicouagan, 1942 km2, elev 360 m, is located in southeastern Québec about 140 km from the Labrador border. The second-largest natural lake in Québec, it was created by a METEORITE millions of years ago. The circular-shaped reservoir contains a centrally situated island, Île René-Levasseur, capped by 952 m high Mont de Babel. Fed by 4 rivers, it drains south, via the Rivière MANICOUAGAN, and empties into the ST LAWRENCE RIVER near BAIE-COMEAU.
Hydroelectric developments have resulted in the damming of the water flow at the 214 m high Daniel Johnson (Manic 5) Dam, one of the world's largest, situated 40 km south of the reservoir (1971). The availability of power has attracted several industries over the years, yet the area still retains its attraction for canoeists, fishermen and wildlife enthusiasts.
Its name is possibly of Montagnais origin and might mean "where there is bark" (for canoe making). The lake appears on Jonathan Carver's map of Québec (1776) as Lake Asturagamicook, and is shown to be drained by the Manicouagan or Black River.
