Lac WinnipegLake Winnipeg is a large freshwater lake in the province of Manitoba, Canada, covering about 24,514 square kilometres and extending roughly 400 to 450 kilometres north to south. It is relatively shallow for its size, with an average depth around 12 metres and a maximum depth near 36 metres.
The lake supports significant commercial and recreational fisheries and is an important feature in regional transportation and culture. Extensive shoreline wetlands and river inflows contribute to its ecological complexity and to water-quality issues in the lake.
Indigenous peoples and later fur-trade enterprises used the lake and its river connections for travel and trade for many centuries. Modern management involves provincial and federal authorities addressing nutrient inputs and fisheries sustainability.
Lake Winnipeg occupies central southern Manitoba and stretches north from the Red River and the city of Winnipeg; the city of Winnipeg sits at the southern end of the lake’s watershed and gave the lake its name.
- Algal blooms: Shallow average depths and long residence time make the lake susceptible to seasonal and recurring cyanobacterial (harmful algal) blooms in warm months.
- Fisheries: A major freshwater resource in Manitoba that supports commercial and subsistence fisheries, notably for walleye and whitefish.
