The Bow River, a major waterway in Alberta, Canada, originates in the Rocky Mountains at Bow Lake and flows southeast through Banff National Park, Calgary, and the prairies before joining the Oldman River to form the South Saskatchewan River. Renowned for its clear, turquoise waters and scenic beauty, it supports diverse ecosystems, including trout fisheries, and provides drinking water, irrigation, and hydroelectric power. The river is also a hub for recreation, offering opportunities for fishing, kayaking, and riverside trails.
