The small community of ''Misi-zhaaga'iganiing
was established by trapper Johnny Kenequanash in the 1940s on the central western shore of McDowell Lake, known in Oji-Cree language as Misi-zhaaga'igan
, meaning "the grand lake." Misi-zhaaga'igan'' was the main water way for people travelling by canoes leading North to
Windigo Lake or going east towards
Cat Lake. Kenequanash and his family was soon joined by the James family. Most Band members were former
North Caribou Lake (Weagamow Lake) members and also have close ties with
Cat Lake members. For many years the prime economic activity is either trapping or commercial fishing. In 1985, McDowell Lake along with six other community was awarded official Band status. The Governments of Canada, Ontario, the
Nishnawbe Aski Nation and six of its member First Nations (
Aroland,
Keewaywin, McDowell Lake,
New Slate Falls,
Saugeen, and
Wawakapewin) signed an agreement in December 1991 to make lands available to establish
Indian reserves in the six communities and to provide basic community facilities. In June 1992, the 4455
ha MacDowell Lake Indian Settlement was remitted, but Census Canada records only 2750 ha in 1996 and 1940 ha in 2006. ==Government==
