By the mid-19th Century, this sector has grown mainly through agriculture and forestry. Intensive logging generated logs which were deposited on the ice during winter. Driftwood down the Matawin River to the Saint-Maurice River, to feed the pulp and paper mills downstream, such as those of Grand-Mère Shawinigan and Trois-Rivières. From the 20th century, recreation and tourism are major activities in the region.

Initiatives for the creation of a recreation area date back to 1992, but the park itself was officially founded in 2005.

The park is located 155 kilometres (96 mi) north of Montreal. Lac Taureau park shares its eastern limits with Mastigouche Wildlife Reserve. The large reservoir of Lake Taureau covers 95 square kilometres (37 sq mi). This large lake has 31.7 kilometres (19.7 mi) of banks including many sandy beaches, including the beach of Pointe-Fine located at the end of a peninsula jutting off the center of the lake. This lake has 45 islands. The sandy shores of "Baie du Milieu" (bays of the Middle), and "Baie des embranchements" (baie of Splitter) and "Baie du Poste" attract fans of camping and swimming in a wildness.
