Lake Winnipeg is Canada's sixth-largest freshwater lake [3] and the third-largest freshwater lake contained entirely within Canada, but it is relatively shallow (mean depth of 12 m [39 ft]) [4] excluding a narrow 36 m (118 ft) deep channel between the northern and southern basins. It is the eleventh-largest freshwater lake on Earth.
Lake Winnipeg ranks as the 11th largest freshwater lake in the world by surface area. The lake consists of three well-defined regions, the larger North Basin, the smaller South Basin, and the connecting body of water defined as the "Narrows", all of which are greatly affected by algae blooms.
This increase in phosphorus is likely a result of increased nutrient input from a combination of wastewater treatment, agricultural inputs, and atmospheric depositions. Elevated phosphorus concentrations promote excessive algal bloom growth, which have many undesirable outcomes for the watershed and the entire Lake Winnipeg basin.

Sandy Islands is a group of four islands located in the northern basin on Lake Winnipeg in the Canadian province of Manitoba. The Sandy Islands together with Little George Island, George Island and the Spider Islands form a chain of islands, which are a continuation of The Pas Moraine.
The river's physical characteristics include whitewater rapids, large lake systems, waterfalls, deep valleys and gorges, as well as tidal flats. [2] It is 483 kilometres (300 mi) long, has a mean discharge of 590 cubic metres per second (21,000 cu ft/s), and its drainage basin covers 108,000 square kilometres (42,000 sq mi).
The river is a part of a proposed United Nations World Heritage Site to protect the large intact area of wilderness along Lake Winnipeg and in northwestern Ontario. This wilderness river is one of the few rivers in southern Canada that is still very pristine and clean, with little or no development along the shoreline and in the entire watershed.
Reindeer Island is an island located in the north basin of Lake Winnipeg, in the Canadian province of Manitoba, closer to the western shore of the lake.Uninhabited by people, it was named Manitoba's first ecological reserve in May 1976, [1] and was created under The Crown Lands Act. [2]
