Introduction

For the purposes of this virtual exhibit, the Lake Saint-Pierre biosphere reserve has been subdivided into two main sections: the Lake Saint-Pierre archipelago and Lake Saint-Pierre.

The Lake Saint-Pierre archipelago is made up of around a hundred islands, separated by numerous channels. The north and south shores of the St. Lawrence that surround the archipelago are also covered in this section of the exhibit.

The Lake Saint-Pierre archipelago takes up the western part of the reserve, bounded by Berthierville to the north and Sorel-Tracy to the south. It stretches east to La Grande Pointe on the northern shore (just after Îles de la Girodeau) and to the mouth of the Yamaska river in the south.
