The Shebandowan River is a river in Thunder Bay District in Northwestern Ontario, Canada.[1] It is in the Great Lakes Basin and is a left tributary of the Matawin River. Three-quarters of the length of the river valley is paralleled by Ontario Highway 11, at this point part of the Trans-Canada Highway; and the entire length of the river valley is paralleled by a Canadian National Railway main line, built originally as the Canadian Northern Railway transcontinental main line.
The river begins at Lower Shebandowan Lake,[2] part of a trio of lakes (Upper, Middle and Lower Shebandown lakes) known collectively as Shebandowan Lakes,[3] in geographic Conacher Township.[4] It exits the lake east over a dam at the community of Shebandowan,[5] passes into geographic Blackwell Township,[6] continues east into geographic Dawson Road Lots Township,[7] and takes in the left tributary Oskondaga River south of the community of Shabaqua Corners.[8] The river leaves Ontario Highway 11 and turns southeast into geographic Laurie Township,[9] passes the community of Shabaqua,[10] enters geographic Horne Township,[11] and reaches its mouth at the Matawin River. The Matawin River flows via the Kaministiquia River to Lake Superior.
