Southeast of Calgary and southwest of Lethbridge, the Oldman River is a popular fly fishing river that is known for its four species of trout.
The fly fishing on the Oldman River is usually divided into three sections: the upper Oldman River, the middle Oldman River, and the lower Oldman River. The upper section is in the high country, has deep pools with several tributaries, and is known for Westslope Cutthroat trout and Bull trout. It is best in late June. The middle section is below the foothills and can be either waded or floated. The best time of year is May. The lower section is known as the Oldman River Tailwater, is open yearround and is best floated.
Overall, Oldman River is the 7th most popular fly fishing river of all 9 fly fishing spots in Alberta.
