La Grande River ((フランス語:La Grande Rivière), (クリー語:Chisasibi), both meaning "great river") is a river in northwestern Quebec, Canada, which rises in the highlands of north central Quebec and flows roughly west to drain into James Bay. It is the second largest river in Quebec, surpassed only by the Saint Lawrence River. Originally, the La Grande River drained an area of and had a mean discharge of 1690 m³/s. Since the 1980s when hydroelectric development diverted the Eastmain and Caniapiscau Rivers into the La Grande, its total catchment area has increased to about , and its mean discharge increased to more than 3400 m³/s.〔Hydro-Québec and GENIVAR Groupe Conseil inc., ''Environmental Monitoring of the La Grande-2-A and La Grande-1 Projects.

At one time, this river was known as the "Fort George River". The Hudson's Bay Company operated a trading post on the river at Big River House from 1803 to 1824. In 1837, a large trading post was established at Fort George on an island at the mouth of the river. In the early 20th century, this trading post became a village as the Crees of the James Bay region abandoned their nomadic way of life and settled nearby. The modern Cree village of Chisasibi, which replaced Fort George in 1980, is situated on the southern shore of the La Grande River, several kilometers to the East. ==Tributaries== Significant tributaries of La Grande River include: *Kanaaupscow River *Sakami River * *Eastmain River (diverted) * * *Opinaca River * * *Rupert River (diverted) *Rivière de Pontois * *Rivière de la Corvette *Laforge River * *Caniapiscau River (diverted) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「La Grande River」の詳細全文を読む スポンサード リンク
