Location of the mouth of the Mattagami River in OntarioThe Mattagami River is a river in the James Bay drainage basin in Cochrane District, Timiskaming District and Sudbury District in Northeastern Ontario, Canada.[1][2]
The Mattagami flows 443 kilometres (275 mi) from its source at Mattagami Lake in geographic Gouin Township[3] in the Unorganized North Part of Sudbury District, on the Canadian Shield southwest of Timmins,[4] to Portage Island in geographic Gardiner Township[5] in the Unorganized North Part of Cochrane District, in the Hudson Bay Lowlands.[6] Here the Mattagami's confluence with the Missinaibi River forms the Moose River, about 100 kilometres (60 mi) from that river's tidewater outlet at James Bay.[7] The Mattagami River flows through the city of Timmins as well as the town of Smooth Rock Falls[7] and its drainage basin encompasses 37,000 square kilometres (14,000 sq mi).[4]
The Mattagami's name comes from the Ojibwe and means either "the start of water" (maadaagami) or "turbulent water" (madaagami).
