Granville Lake (Cree: ᐅᑳᐏᒥᖨᐦᑳᓈᓂ, okâwimithihkânâni[2]) is an Indian settlement located on a peninsula on the south shore of Granville Lake (part of the Churchill River system) in northern Manitoba. The community is primarily a settlement of the Mathias Colomb First Nation, who now live in nearby Leaf Rapids.[3]
The community does not have all-weather road access; rather the community relies on ice roads in the winter and the lake-river system in the summer.
In the 2006 census, Granville Lake had a population of 98 living in 16 dwellings, a 42.0% increase from 2001. At that time, the settlement had a land area of 2.33km2 and a population density of 42/km2.[4] In 2011, its population dropped to just 10 inhabitants,[5] as the community shifted to Leaf Rapids.
