Manitoba Lowland
Quick Summary
The Manitoba Lowland is a region in Canada that was once the basin of glacial Lake Agassiz. Today, remnants of this ancient lake include Lake Winnipeg, Lake Winnipegosis, and Lake Manitoba. This area is characterized by fertile, level prairies and rolling pastures in the south, with upland plateaus, wooded river valleys, and swamps further north. The region is drained by the Red River of the North and the Assiniboine River, flowing into Lake Winnipeg. Much of this river region is a natural floodplain, though modern flood-control measures have helped mitigate inundation.1
