Lake Winnipegosis

geography Maturity 11-13 Next article →

Lake Winnipegosis is a massive freshwater body located in central North America. It sits within the province of Manitoba, Canada. The lake is positioned roughly 300 km northwest of the city of Winnipeg. With a surface area of 5,370 km2, it holds a significant place in the region. It is currently ranked as the eleventh-largest lake in Canada. The name of the lake offers a clue to its appearance. The word Winnipeg means "big muddy waters." By adding a diminutive suffix, the name Winnipegosis translates to "little muddy waters." This name likely refers to the coastal wetlands found around the lake.

The lake has a distinct, elongated shape. It stretches for a total length of 195 kilometers. Geologically, the lake rests on the floor of a prehistoric body of water. This ancient glacial lake was known as Lake Agassiz. Lake Winnipegosis is the second-largest of three major lakes in central Manitoba. The largest is Lake Winnipeg, and the third is Lake Manitoba. These lakes share a common history tied to the movement of ancient glaciers.

Water moves through this system in a specific sequence. Most of the water entering the lake comes from the Manitoba Escarpment. A large watershed of 49,825 km2 feeds the lake across Manitoba and Saskatchewan. Many different rivers, known as tributaries, flow into the lake. These include the Mossey River, which comes from Dauphin Lake. Other tributaries are the Point, Pine, North Duck, Pelican, and Shoal rivers. The Steeprock, Red Deer, and Overflowing rivers also contribute to the lake's volume.

Once the water enters the lake, it eventually finds a way out. The lake drains through the Waterhen River. This process begins at Long Island Bay at the southeast end. From there, the West Waterhen and Little Waterhen rivers flow north for about 16 km. They empty into Waterhen Lake. Finally, the Waterhen River flows south for 22 km into Lake Manitoba. This movement makes Lake Winnipegosis part of several larger systems. It is connected to the Lake Winnipeg, Nelson River, and Hudson Bay watersheds.

Land barriers separate Lake Winnipegosis from its neighbors. At the northern end, a land barrier 6 km wide separates it from Cedar Lake. At the southeast end, a 3 km wide barrier exists at Meadow Portage. This barrier separates the lake from Lake Manitoba. Within the lake itself, Birch Island is the largest island. It is located near the middle of the lake. Birch Island is part of Birch Island Provincial Park, which was established in 2010. The island sits adjacent to the Chitek Lake Park Reserve on the eastern shore.

Human communities are spread around the edges of the water. Several towns are located south of Birch Island. These include Winnipegosis, Camperville, Pine Creek, Duck Bay, Salt Point, and Meadow Portage. Other communities are found to the north of the island. These include Shoal River, Pelican Rapids, Dawson Bay, and Denbeigh Point. The lake is a vital resource for these people. It supports many different types of economic and social activities.

The lake is a highly active multi-use fishery. It supports Indigenous domestic harvests and recreational angling. It also supports a commercial fishery for walleye and other freshwater species. Certain fish species are especially important to the local economy. Northern pike and mullet are very prominent in these waters. Together, these two species account for over 80 percent of the commercial fishing. This makes the lake a central part of the regional ecosystem and economy.
