Geography

The river takes its waters from a set of lakes in the east and southeast of the Eastmain Reservoir; the upper lake is 5.7 km south of Eastmain or at the east of a highest peak at 450 meters. In this very complex headwaters, the river passes through numerous lakes and marshes, such as Cramoisy lakes, Teilhard, Biggar and Mountains.

At the end of its course, the river flows in norther edge of the Lake Nemiscau, which matches the shape of a U open towards the northeast. The other end of this U receive waters from Rupert River. The Lake Nemiscau is located north of Lake Giffard and Lake Evans, and to the south of the Jolliet Lake.
Toponymy
In 1672, the explorer Charles Albanel (Catholic priest) had awarded the place name "Nemiskausipiou" to name the Rupert River today. During his 1679 trip, Louis Jolliet was also reference to "Nemisco" to describe the current Rupert River. Handwritten notes indicate Jolliet, "My land was entered by the Saguenay, which comes close to a large lake, named "Timigaming" (the Lake Mistassini), the source River Némiskau (ie Rupert), which discharges into the North Bay (the James Bay), on which I made my way to the sea."
The "Nemiscau" name designating that river is in use since the 1940s. Because of upwelling, this river became the Nemiscau Lake, before the waters join the Rupert River. In 1982, Quebec Names Board formalized the movement toponymique pointing this river "Rivière Nemiscau".
In 1690, maps refer to the name "Rupert" which refers to the river and the fort. Subsequently, the cards of Claude-Charles Bacqueville de La Potherie use the spelling "R. Rupert" and those of Father Laure in 1731-1732 "R. Rupert." In 1744, Nicolas Bellin also uses graphieu "R. Nemiscau".
Later, the name "Rupert River" prevailed until the twentieth century. The place name Nemiscau was recovered, but moving to the northeast to identify the branch of the river remained unnamed until the 1940s.
Cree language, the term "Nemiscau" means "where fish are abundant". "François R." on the card entitled "Party of New France" by Alexis Jaillot, Paris, 1685. "Miskoutenagachit" is on the "Map of Canada or New France and discoveries that were there made" by Guillaume Delisle, Paris 1703. The card "A New and Exact Map of the Dominions of the King of great Britain on ye continent of North America" ([London], 1715, revised in 1732 or after) shows "Miskautenagachit R".
The place name Nemiscau River was formalized on Dec. 2, 1982 to the Bank of place names in Commission de toponymie du Québec (Quebec Names Board).
