Some may argue that the Bighorn is the best trout water in the lower 48. Crystal clear water, steady flows and proficient insect populations produce big healthy brown & rainbow trout. Biologist fish counts vary from 5,000-10,000 trout per mile depending on the stretch of water. Good fishing can be found up to 35 miles down from the Afterbay Dam, with the most consistent fishing being on the upper 13 miles. Keep in mind that the Bighorn flows through the Crow Indian Reservation and shore access may be off limits depending on location. The town of Fort Smith lies at the beginning of the river where gas, food, flies and lodging can be found.
