The province of Manitoba, Canada, contains three of the world’s largest freshwater lakes; Lakes Winnipeg, Winnipegosis and Manitoba. A significant feature of these lakes are their extensive coastal wetlands. A GIS-inventory found the Manitoba Great Lakes have six times more wetlands per km of shoreline than the Laurentian Great Lakes. Lake Winnipeg has a coastal wetland area of 1,404 km2, Lake Manitoba has 564 km2, and Lake Winnipegosis has 742 km2. Netley-Libau Marsh (222 km2) on Lake Winnipeg, and Delta Marsh (185 km2) on Lake Manitoba, are believed to be the largest freshwater coastal wetlands in North America. These wetlands provide many benefits to their adjoining lakes, and provide important wildlife and fisheries habitat. However, lake-level regulation, nonpoint source nutrient pollution and invasive species are significant threats to these coastal wetlands and the ecosystem benefits they provide.
