Located in south-central Montana near the edge of the Crow Indian Reservation, Fort Smith is home to one of the most iconic tailwater fisheries in the country—the Big Horn River. This stretch is known for its cold, clear water, prolific insect hatches, and thriving populations of wild brown and rainbow trout.

Fishing here is consistent across all four seasons. Spring and fall bring strong baetis and midge hatches, while summer offers a range of techniques depending on conditions. In winter, anglers enjoy solitude and actively feeding fish thanks to stable flows from the Yellowtail Dam.
