Seine River Watershed
Information
Location
Location
The Seine River is located in Northwestern Ontario and gathers its flow from a teardrop-shaped watershed having an area of approximately 6,250 square kilometres. The headwaters originate at the Savanne River at Raith (near Upsala Ontario, northeast of Atikokan). The river flows westerly for 250 kilometres and empties into Rainy Lake (near Fort Frances, Ontario, and the Canada/USA border). The Seine River is part of the Winnipeg River drainage system that flows west through Ontario and north through Manitoba to Hudson Bay.
