About Tongue River
The Tongue River, a Montana gem originating in Wyoming's Bighorn Mountains, offers a unique fly fishing experience, particularly in the first ten miles below the Tongue River Reservoir dam where it carves through a canyon. This section, with deeper, cooler waters, is ideal for targeting rainbow and brown trout, as well as smallmouth bass. Successful fly patterns often mimic local insect activity, with Pheasant Tail nymphs, Wooly Buggers, and imitations of Yellow Sally, PMD, and Caddis proving effective. Anglers can access the canyon stretch via wading or floating, with the latter requiring shuttle arrangements. Beyond the canyon, the river transitions to support species like channel catfish, sauger, and walleye. Nearby Tongue River Reservoir State Park provides convenient camping and family amenities.
