Trois-Rives is a municipality with an area of 675km2 located in Mékinac Regional County Municipality, in the Mid-Mauricie, province of Quebec, Canada.
It is bounded on the west by the Saint-Maurice River, and includes the communities of Grande-Anse, Olscamps, Rivière-Matawin, Saint-Joseph-de-Mékinac, and partially Rivière-aux-Rats.[2]
The territory also includes in the east portions of Mékinac Lake (in part), Missionary Lake (in part), aux Loutres, and Dumont Lakes.
The toponym "Trois-Rives" (three banks) refers to the three rivers that drain the territory: the Matawin River, the Saint-Maurice River and the Mékinac River.
It was established in 1972 as Boucher, named after the geographic township of Boucher in which it is located. This name was chosen in honour of Pierre Boucher, former French governor of Trois-Rivières and owner of the Boucher and Boucherville Seignories in the late 17th century. It was not until 1978 that the municipal incorporation was confirmed.[3]
On December 26, 1998, the municipality was renamed to Trois-Rives (French for "Three shores") to better represent the geography of the municipality as it is crossed by three rivers: the Matawin, the Mékinac, and the Saint-Maurice River.[3]
On August 28, 2004, Trois-Rives was enlarged by some 70km2 when it annexed a portion of the Lac-Masketsi Unorganized Territory.
The municipality has two main roads: Quebec Route 155 (along the Saint-Maurice River on the eastern shore); and St. Joseph road through the village of Saint-Joseph-de-Mékinac along the Mékinac River, reaching the Quebec Route 155 near the mouth of that river. The path of almost all other roads goes along the rivers. Generally, each route is designated as the place name of the headwater lake that feeds it:
