The toponym "rivière des Rosiers" was made official on December 5, 1968, at the Commission de toponymie du Québec.

[1] The "rivière des Rosiers" watershed affects six municipalities, namely (from upstream to downstream) Saint-Rémi-de-Tingwick, Tingwick, Kingsey Falls, Warwick, Sainte-Élizabeth-de-Warwick and Saint-Albert.

It then flows in a northwesterly direction to empty into the Nicolet River at Saint-Albert at an altitude of 103 metres (338 ft).

The main species are horned mullet (Semotilus atromaculatus), black sucker (Catostomus commersoni), belly-rotten (Pimephales notatus) and the Redfin Shiner (Luxilus cornutus).

There are, among others, several species of buntings, warblers, swallows, tyrants, vireos, thrushes, and some representatives of corvids, such as the Raven and the Blue Jay.
