Reindeer Lake

Reindeer Lake lies in the forests of northern Canada, on the border between Saskatchewan and Manitoba. It is the ninth-largest lake in Canada and is known for its clear, deep water and many islands.

The story behind it

Reindeer Lake is about 230 kilometres long, and its shore is full of bays, points and small islands. Almost all of it, 92 per cent, lies in Saskatchewan; the rest belongs to Manitoba. Its name seems to be a translation of an old name in an Algonquian language. Near the south-western end lies Deep Bay, a strikingly round bay about 220 metres deep. Scientists think it formed in a 13-kilometre crater left by a rock from space that hit the Earth about 99 million years ago. The water leaves the lake through the Reindeer River and flows via the Churchill River to Hudson Bay. Since 1942 the Whitesand Dam has controlled the outflow and raised the water by about two metres. Small communities such as Southend, Kinoosao and Brochet lie on the shore, and anglers come to catch northern pike, walleye and lake trout.

Questions children ask

How big is Reindeer Lake?

Reindeer Lake covers about 6 650 km² if its many islands are counted; the water surface alone is given as about 5 658 km². It is the second-largest lake in Saskatchewan and the ninth-largest in Canada.

What is Deep Bay?

Deep Bay is a round, very deep bay at the south-western end of Reindeer Lake. It lies in a crater about 13 km wide that a rock from space made about 99 million years ago.

Is Reindeer Lake held back by a dam?

Reindeer Lake is a natural lake, but since 1942 the Whitesand Dam has controlled the water flowing out. The dam raises the lake by about two metres.
