Trois-Rives is a forest and resort town in the Middle-Mauricie region located in the Laurentian Shield, on the north shore of the St. Lawrence River, in the regional county municipality of Mékinac, in Mauricie, in Quebec. This municipality has a territory of 650.7 kilometres (404.33 mi) where 396 inhabitants reside.
The municipality of Trois-Rives is crossed in its western part by the Saint-Maurice River which is 49.7 km on the east shore and 53.7 km on west shore. The territory of the East shore of Saint-Maurice River is divided by the Mékinac River. This municipality has known several eras of economic activities derived from the forestry industry, agriculture and recreational tourism activities.
In Trois-Rives, the logging industry has been dominant in local history.
Route 155 linking Grand-Mère to La Tuque generates significant traffic, especially in summer. Consequently, jobs are turning to the offer of recreational tourism activities (vacationing, hunting & fishing, mountain biking, snowmobiling, nautical activities, camping, hiking, etc.).
The main centers of attraction of Trois-Rives for recreational tourism activities are: Lake Mékinac, Lake Missionary, the valley of the Saint-Maurice river and the area west of Saint-Maurice (Réserve faunique du Saint-Maurice, Zec du Chapeau-de-Paille and Zec du Gros-Brochet).
In 1972, the municipality was incorporated and designated under the toponym “Boucher”, in order to harmonize with the geographical township of “Boucher”, constituted by proclamation on June 4, 1875 and which is integrated into this municipal territory. This toponym was chosen in honor of Pierre Boucher, former French governor of Trois-Rivières and owner of the seigneuries Boucher and Boucherville at the end of 17th century. However, the municipal incorporation was only formalized in 1978. Finally in 1998, the municipality was renamed “Trois-Rives”.
The Matawin Bridge, spanning the Saint-Maurice River, was erected in 1993; it thus replaced the old ferry and the ice bridge (in winter). It thus provides easier access to the Zec du Chapeau-de-Paille and the Saint-Maurice wildlife reserve.
The Saint-Maurice River has its source at Gouin Reservoir, in Haute-Mauricie. It flows on 560 kilometres (350 mi) in a north-south direction and displays a drop of 405 metres (1,329 ft).
The village of Trois-Rives is accessible by road, snowmobile and all terrain vehicles. However, the eastern part of the territory of Trois-Rives is accessible by the Via Rail Canada passenger train which passes near the western limit of the Zec Tawachiche, on the eastern side of Lake Mékinac.
