Bow River

The headwaters of the Bow River in Alberta, Canada, start at the Bow Glacier and Bow Lake in Banff National Park in the Canadian Rocky Mountains. The glacial stream that feeds Bow Lake has a mean elevation of 2310 metres above sea level. From there, the river winds through the Alberta foothills onto the prairies, where it meets the Oldman River, the two then forming the South Saskatchewan River. These waters ultimately flow through the Nelson River into Hudson Bay.
