The rivers of Quebec are vital to the province's geography and ecology. Major rivers include the St. Lawrence River, which serves as a crucial waterway for transportation and trade, connecting the Great Lakes to the Atlantic Ocean. Other significant rivers, such as the Ottawa River and Saguenay River, contribute to the region's rich biodiversity and provide recreational opportunities. These rivers also play an essential role in hydroelectric power generation, with many dams harnessing their flow to produce electricity. The diverse ecosystems along these waterways support various wildlife and plant species, making them important for conservation efforts in Quebec.
