The Oldman River is the major drainage system of southwestern Alberta, Canada, carving a dramatic path from its headwaters high in the Rocky Mountains, through the foothills, and out across the prairies before eventually joining the Bow River. This river system is a crown jewel of Alberta fly fishing, offering a remarkable diversity of water types and fish species across its length. The upper reaches are classic high-country cutthroat streams — rugged, remote, and breathtakingly scenic — while the middle and lower tailwater sections provide year-round angling opportunities with superb hatches and outstanding dry-fly fishing. The river's character shifts dramatically from section to section, rewarding anglers who take the time to explore its full length.
