The Big Horn River is one of the United States most productive Blue-Ribbon Rivers.  The 3-mile tail water downstream of the Big Horn Damn contains ~7,000 fish per mile, and most fish are over 16 inches with 18-22 inch fish not uncommon.  The following 4 to 12 miles provide a scenic trip through the valley's canyons and pastures.  The Big Horn River tail water is located in Ft. Smith, which is a "very" small town with just the bare bone essentials for a great fishing trip.
