Lake Manitoba, << `man` ih TOH buh, >> lies in the south-central part of Manitoba. It and Lakes Winnipeg and Winnipegosis are remains of glacial Lake Agassiz, which once occupied much of Manitoba (see Lake Agassiz ). Lake Manitoba, the smallest of the three lakes, covers 1,785 square miles (4,624 square kilometers). It is 120 miles (200 kilometers) long and 29 miles (47 kilometers) wide and is unusually shallow. It drains through the Dauphin River into Lake Winnipeg. An important waterfowl research station lies at the south end of the lake, at Delta Marsh.
