The èreduMoulinrivièRivière du Moulin (English: river of the Mill), also called Rivière Langevin, is a tributary of the Saguenay River. Its mouth is located in the Rivière-du-Moulin district, in the east of the Chicoutimi borough in Saguenay. The river is known for its urban park, the Rivière-du-Moulin park, located on its banks near its mouth.
The upper part of the Moulin river valley is served by the forest roads R0287 and by a secondary road descending part of the valley; this upper part is also indirectly served by the route 175 which passes on the west side. A few other secondary forest roads serve the "rivière du Moulin" valley, mainly for forestry and recreational tourism activities.
In addition to the urban and industrial area, crossing the Chicoutimi sector of the city of Saguenay, forestry is the main economic activity in this valley; recreational tourism, second.
The surface of the Moulin river is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March, except in the rapids zone.
Toponymy
The "rivière du Moulin" takes its name from the Sawmill built by Peter McLeod father around 1810 on the river, while he was employed by the Company North West. This name is mentioned for the first time in 1827. The name "Langevin" comes from the Langevin family who formerly owned a flour mill near its mouth. For their part, the Montagnais used the designation "Papawitish" to designate the river. From Le Gardeur de Tilly's report in 1725 until 1825, half a dozen explorers will use this name. "Papawitish" would mean "beaver about 2 to 3 years old" in innu-aimun.
The toponym "Rivière du Moulin" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.

This lake is mainly fed by the outlet (coming from the south-east) from Lake Andrevos and by a stream coming from the east. This lake is located at: south-east of lac de l'Enfer; south-west of the course of the rivière à Mars North-West; north-east of route 175; north-east of the course of the Pikauba River; south-east of the confluence of the "rivière du Moulin" and the Saguenay River.
From the lac du Moulin, the rivière du Moulin flows mainly north for a length of to Saguenay, to finally jump into the Saguenay River.
