The English name, Lake Laberge, was apparently given by W.H. Dall to commemorate a French Canadian, Michael Laberge, from Chateauguay, Quebec. Laberge traveled from Fort Yukon to Fort Selkirk in 1867 as part of the Western Union Telegraph Expedition, but it is not known whether he actually traveled upriver as far as Tàa’an Mǟn. The lake and its location may have been described to him by the local native people.
