Rivière Nottaway

The 398th longest river in the world

775 km

The Nottaway River is a river in Quebec, Canada. The river drains Lake Matagami and travels 225 kilometres (140 mi) north-west before emptying into Rupert Bay at the south end of James Bay. Its drainage basin is 65,800 square kilometres (25, 400 sq mi) and has a mean discharge of 1190 m3/s (1556 yd3/s). Its source is the head of the Mégiscane River, which is 776 kilometres (482 mi) from the mouth. Significant lakes along its course are Soscumica Lake (50°15′N 77°27′W) and Dusaux Lake (50°45′00″N 77°53′30″W). The Nottaway, together with the Broadback and Rupert Rivers, was initially considered to be dammed and developed as part of the James Bay Project. But in 1972 hydro-electric development began on the more northerly La Grande and Eastmain Rivers, and the NBR Project was shelved. With the decision to divert the Rupert River to the La Grande, it is not likely that the Nottaway will be developed in the foreseeable future.
