Toponymy
editThe 1852 map designed by provincial surveyor Frederic William Blaiklock refers to the toponym "R. Des Aunes". The place name “Rivière des Aulnets” is also noted on the map of the township of Bourget in 1881. The land surveyor Jean Maltais, in his report on the township of Bégin, in 1895, mentions “the river of Aulnaies”. Appeared in Regions of Quebec, Lac-Saint-Jean, Chicoutimi and the north coast of the St. Lawrence, Description of surveyed cantons, explorations of territories and surveys of rivers and lakes, from 1889 to 1908, published by the Department des Terres et Forêts, Québec, 1908, page 6. The word aulnaie designates a place planted with alders. The Commission de géographie de Québec, today known as the Commission de toponymie du Québec, adopted the toponym "Rivière des Aulnaies" on November 4, 1948.[4]
The toponym of "Rivière des Aulnaies" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.[2]
