Lake Saint Pierre (French: Lac Saint-Pierre) is a lake in Quebec, Canada, a widening of the Saint Lawrence River between Sorel-Tracy and Trois-Rivières. It is located downstream, and northeast, of Montreal; and upstream, and southwest, of Quebec City.
This lake which is 32 kilometres (20 mi) long (excluding Sorel Islands) and 14 kilometres (8.7 mi) wide, is part of the St. Lawrence Seaway. Including its shoreline, islands, and wetlands, the lake is a nature reserve. The body of water is recognized as Ramsar site and as Biosphere Reserve, due to the presence of many marshes or wetlands that are frequented by waterfowl. Recreational activities on the river (such as fishing, boating, sailing, swimming, water skiing, nature observation) are active mainly in summer season.
The lake is located in the Regional County Municipalities of Nicolet-Yamaska, Maskinongé, D'Autray, and Pierre-De Saurel, in addition to the city of Trois-Rivières. The shores of the lake affect several municipalities:
The lake was named by Samuel de Champlain following its passage on 29 June 1603, the day of the Saint-Pierre. The Abenaki called Lake Nebesek, which means at lac. Jacques Cartier, during his second voyage to Canada in 1535, had given him the name of "Angoulême".
