Canada – May 20th, 2013

Ice covers the northern part of Lake Winnipeg, in Manitoba, Canada, visible at the center of the bottom edge of this image. The shores of the Hudson Bay are also lined with ice (upper right quadrant), and sediments can be seen spilling from the Nelson River into the bay.

Climate change has the potential to affect the ecology and biology of Lake Winnipeg. Climate-forcing scenarios predict increases in mid-summer temperatures through the 21st century, with even greater increases in mid-winter temperatures, extending the open water season.

Canada – May 6th, 2013

Lake Winnipeg is the largest aquatic life support system in Manitoba, covering some 24,500 sq km. It sustains a complex food web and the largest commercial fishery west of the Laurentian Great Lakes.

Like many natural systems, the lake is shaped by environmental forces and disturbed by human activities. Weather, climate, and geology regulate the growth and reproduction of its plants and animals.

But excess nutrients from urbanization, agriculture and economic development in the Lake Winnipeg watershed are impairing its water quality and, in spite of its size, Lake Winnipeg is susceptible to the impacts of climate change (click here for more information).

This APM image shows the southern reaches of Lake Winnipeg, a large, 24,514-square-kilometre (9,465 sq mi) lake in central North America, in the province of Manitoba, Canada. Its southern tip is located about 55 kilometres (34 mi) north of the city of Winnipeg.

Lake Winnipeg is the sixth-largest freshwater lake in Canada, but it is relatively shallow (mean depth of 12 m (39 ft), excluding a narrow 36 m (118 ft) deep channel between the northern and southern basins. It is the eleventh-largest freshwater lake on Earth. The east side of the lake has pristine boreal forests and rivers that are being promoted as a potential United Nations World Heritage Park. The lake is elongated in shape and is 416 km (258 mi) from north to south, with remote sandy beaches and large limestone cliffs.
