Rivière du Moulin (Deschambault-Grondines)


The rivière du Moulin is a tributary of the northwest shore of the Saint-Laurent river, descending in the municipality of Deschambault-Grondines, in the Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, in Canada.
The Moulin river valley is mainly served by the route 138 which runs along the northwest shore of the St. Lawrence River and the route 363 which is perpendicular to the north bank of the river.
Agriculture is the main economic activity in the sector; forestry, second.
The surface of the Moulin river is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally from late December to early March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.

Toponymy

In Description topographique... du Bas Canada..., published in 1815, the geographer Joseph Bouchette, wrote about the seigneury of Grondines, that it was very well watered by the Sainte-Anne river, the Batiscan, and a small river that falls in the St. Lawrence. The latter runs a grain mill and a sawmill. Still unnamed in 1815, this small river certainly received the name it now bears from the mill it once fed.
The toponym "Rivière du Moulin" was formalized on December 5, 1968 at the Place Names Bank of the Commission de toponymie du Québec.
