This zone is located on the west side of route 273.

Its confluence is located west of the confluence of the Chaudière River.

## Toponymy

The origin of this toponym is associated with the alders which constitute a tree growing along its banks. This plant thrives mostly in moist or well-watered soils.

The toponym of this watercourse has existed since at least the end of the 18th Century, when the first settlers settled in the current sector of Saint-Nicolas. In the 18th century, the Abenakis came to spend the summer near its confluence. At the beginning of the 19th century, the development at the mouth of this watercourse favored the establishment of Ross work sites devoted mainly to forestry; their activities ceased around 1889.

The Aulneuse river has been designated according to several toponyms. A seigneurial plan of 1815 and a map by the Bayfield hydrographer (1859) give it the English name of "Gaspé River". Cartographic and other documents dating from 1925, 1937, 1953 and 1966, indicate the name of Rivière Auneuse. Other sources show Rivière des Aunes (1912), Rivière aux Neux (1916), Rivière aux Nœuds (1918), Rivière Noailles (1976), Rivière Rouard (1918), Rivière Rouër (1918), Rivière Vicontent (1846, 1915 and 1937).

The toponym “Rivière Aulneuse” was made official on March 9, 1988, at the Commission de toponymie du Québec.
