The Great Slave Lake ( English Great Slave Lake ; French Grand lac des Esclaves ) is a lake in central northern Canada , in the Northwest Territories .

The lake has a water surface of 27,048 km². With the islands in it, the area is 28,568 km². With a maximum depth of 614 meters, the Great Slave Lake is the deepest lake in North America.

It is fed by the Slave River and the Hay River , among others . The Lockhart River flows into McLeod Bay in the far northeast of the lake, the Frank Channel drains Marian Lake into the North Arm , and the Taltson River flows into the lake east of the Slave River. The Mackenzie River , one of the largest rivers in North America, forms the drain of the Great Slave Lake . The main town on the largely sparsely populated lakeshore is Yellowknife .

The lake surface is 156  m above sea level, so that due to the extreme depth of the lake, the lake bed is up to 458 meters below sea level. Thus, the Great Slave Lake is a cryptodepression .

Origin of name

The name of the lake has nothing to do with slavery , but goes back to the name of an Indian tribe ( Slavey ) who settled in the area. The German translation of the name, like the French Esclave for slave, is a misunderstanding that has historically become commonplace. The name of the local tribe used to be reproduced phonetically as slave in English , but in modern times - especially to avoid the association with the term "slave" - ​​this has been changed to Slavey . For the lake, however, the old name is still used unchanged in English.
