This river flowing over 14 kilometres (8.7 mi) rooted at the mouth of Pierre-Paul Lake, located in Rang Saint-Pierre, in the eastern part of the territory of Saint-Tite.

From its source, the river flows through the "road Pierre-Paul" and headed straight north across four lots in row St-Thomas (South) situated in the territory of Saint-Tite, then continuous in Sainte-Thècle, draining 10 lots in row St-Thomas (South), where it crosses the first time the road Charest.

With its tributaries streams, Pierre-Paul River receives the waters of 4th row Northeast Rivière des Envies and a small area of northern territory of Saint Séverin.

Pierre-Paul river then branches off into Saint-Tite on 120 degrees to the left to go straight north through four lots in the row St-Pierre Saint-Adelphe.

At the end of the 19th and early 20th centuries, Pierre-Paul River was used especially in the spring (or during large floods) for timber transport by flotation this which involved activities loggers or "cageux".

[4] At the end of the 19th century, an ice road was laid from December to March on Pierre-Paul River to flow more easily to woodlots or to Saint-Tite before the land routes were fit for wheeled freight vehicles, especially to cross the streams.

This forestry road was necessary for logging industry, to more easily reach Saint-Stanislas and allow the priest of Sainte-Thècle to make the trip for serving families of the futur Saint-Adelphe parish.

This river flows south crossing on 3 kilometres (1.9 mi) (almost in a straight line) 11 farm lots in row St-Émile in Saint-Adelphe up to the bridge of St-Emile road.

[7] These artifacts dated from the "prehistoric archaic" period (BC) were mostly cut and polished stones, as instruments of hunting and working in Native American prehistory.

[8] These Native American artifacts have been found around the "creek Piché" and a tributary stream (coming from North), about 2.3 kilometres (1.4 mi) in a straight line from the Batiscan River.
