The Pierre-Paul River flows into the Mékinac Regional County Municipality, in the administrative area of the Mauricie, in the province of Quebec, Canada, through these three municipalities of the Batiscanie: Saint-Tite, Sainte-Thècle and Saint-Adelphe.
Course
This river flowing over rooted at the mouth of Pierre-Paul Lake, located in Rang Saint-Pierre, in the eastern part of the territory of Saint-Tite. Because sometimes mountainous terrain, the main course of the river described a big "Z" through a predominantly agricultural land (a forest in the early part of the course, due to the reforestation of former agricultural land in the area north of Pierre-Paul Lake).
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. At around from its source, the river is a small prank on two lots in row St-George (South) in Sainte-Thècle. Pierre-Paul river receives water from most largest tributaries of the row St-George (South), including Gagnon creek that empties into the river Pierre-Paul on the lot 351-116 of rang St-Thomas (at the limit of rang St-Georges).
The second segment of its course is almost in a straight line and flows on . Pierre-Paul river bifurcates in rang St-George (South) to almost 160 degrees to the right to head straight south. In this segment of its course, the river flow back into row St-Thomas (South) where it crosses again the road Charest and crossing in diagonal six lots. Its path then crosses the limit of Saint-Adelphe and cut nine lots of row St-Emile. The river is then only from its source. The river continues to flow on six lots in row St-Pierre, before making a small prank on three lots in the 4th row Northeast Rivière des Envies (in Saint-Tite). 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.
The third segment of the route is along . 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. It course cut eight lots in row St-Alphonse and some lots of the Southwest of the Batiscan River. In the end of course, the river makes a few curves before throwing in the Batiscan River (on the southwest side), up to the village of Saint-Adelphe. In 1925, the municipality built a new covered bridge on Pierre-Paul River, almost at its mouth, that is the current road 352.
History
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". In spring 1872, Felix Lafontaine and his men (Edward Methot, Irvine Johnson, Alfred Buist, Pierre Bordeau (son of Michael), Pierre Lafontaine (son of Hilaire) and Georges Thiffeau (son of Hubert) were down logs in-beyond the causeway on the small river and owned by Price Brothers. On May 9, 1872, these men were arrested and accused of taking possession of the road May 9, 1872 the Constitutional.
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.
Close to its mouth, the bridge of the route 352 crosses Pierre-Paul river at the village (South West side of the Batiscan river).
Arm of Pierre-Paul River
The creek "Piché" drains much of the farmland in row St-Thomas of Sainte-Thècle cutting perpendicularly twenty lots on about (from North to South) up to Rompré road designated route 352 (linking Saint-Adelphe and Sainte-Thècle). The crossing of creek Piché and route 352 marks the boundary between the two municipalities. On its path in row St-Thomas, creek Piché has collected the waters of two small tributaries (one is creek Francoeur) that drain two areas of southeastern row Saint-Georges. After the foundation of Sainte-Thècle (in 1873), the settlers built a forestry road in this area in order to connect Sainte-Thècle to Batiscan river. 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 road was hardly suitable in summer for wagon until the 19th century. The overflow of the creek Piché blocked temporarily the road every spring, preventing them from circulating.
