The story behind it
Lac la Ronge is the fifth-largest lake in Saskatchewan. Together with its islands it covers about 1 413 km²; the water alone covers about 1 333 km². At its deepest it is about 42 metres deep. The lake lies about 250 km north of the city of Prince Albert, on the edge of the Canadian Shield, a huge area of very old rock. In the Ice Age, glaciers scraped over the land and carved more than 1 300 granite islands, most of them in the northern part of the lake. On the western shore lie the towns of La Ronge and Air Ronge and the Lac La Ronge First Nation, a community of Indigenous people. Highway 2 runs along this side of the lake. Several rivers flow in, and the Rapid River carries the water out over Nistowiak Falls into the Churchill River. Anglers catch walleye, northern pike and lake trout here.
