 In Western Canada, it was common for settlers to arrange themselves by ethnicity to form Block Settlements, and in this area, most settlers were Ukrainian, Russian, or Polish.To the east of the range lie the Manitoba Lowlands, which consist of many interconnected lakes, including Lake Winnipegosis, Dauphin Lake, and Lake Manitoba.The lakes in this lowland region (with the largest being Lake Winnipeg) are the last remnants of Lake Agassiz.
