It is the main village of the Black Lake Denesuline Nation reserve with a land base of over 32,000 hectares (79,074 acres). Formerly, the Black Lake band used the name "Stony Rapids", which is now the name of a separate community 20 kilometres (12 mi) northwest and downstream on the Fond du Lac River, not on reserve land.
Like nearby Stony Rapids, for most of the year Black Lake is not accessible via road from the rest of the province. There is a local secondary highway providing access between it and Stony Rapids, however, during winter a seasonal road connects the area to Saskatchewan Provincial Road 905 and points south.
Black Lake Dene Nation is a band government with territory at three locations: Chicken 224, Chicken 225 and Chicken 226.
Chicken 224 (25819.40 hectares) which includes the village of Black Lake (population 1.070 in 2011) extends from Black Lake up to the border of the village of Stony Rapids. It includes territory on both sides of the Fond du Lac River.
Chicken 225 (2183.40 hectares)(population 0 in 2011) is on the north side of the river and borders Chicken 224.
Chicken 226 (4216.90 hectares)
Black Lake First Nation had a total registered membership of 2,044 with 1,592 members residing on-reserve and 452 members residing at locations off-reserve in September, 2013. It is a member of the Prince Albert Grand Council.
