Suggested renaming

In the late 2010s, many placenames within the Northwest Territories were restored to their indigenous names. It has been suggested--particularly because of the mention of slavery--that the lake be renamed as well. "Great Slave Lake is actually a very terrible name, unless you're a proponent of slavery," says Dëneze Nakehk'o, a Northwest Territories educator and founding member of

organization Dene Nahjo. "It's a beautiful place. It's majestic; it's huge. And I don't really think the current name on the map is fitting for that place." He has suggested Tu Nedhé, the Dene Soline name for the lake, as an alternative. Tucho, the Dehcho Dene term for the lake, has also been suggested.
