One of Alberta's greatest rivers, the Bow River meanders 623 kilometres (387 miles) beginning at Bow Glacier and flowing south through Banff National Park and Calgary. Flowing through Calgary's centre, the river serves as one of the city's main water sources (the other is the Elbow River in Calgary's south). In the summer, people use the river for floating through the city in rafts. Out of the city, the river is widely used by fly fishers, kayakers, birdwatchers, canoeists and more. The river is also an important water source for prairie farmland.
