The Saint Joe River, located in the Idaho Panhandle, is one of Idaho's premier native trout fisheries. Flowing for approximately 140 miles from its headwaters in the Bitterroot Mountains to Lake Coeur d'Alene, this clear, cold river is designated as a Wild and Scenic River along 66.3 miles of its upper reaches. Known historically as the Shadowy St. Joe for its tall forests that hug the riverbanks, it offers anglers exceptional catch-and-release opportunities for native westslope cutthroat trout in a breathtaking mountain setting. The river drops over three-quarters of a mile in elevation during its journey, creating diverse habitats from swift headwaters to deeper, more languid sections downstream, making it a versatile destination for fly fishers seeking beautiful native trout in pristine surroundings.
