About this water

The Bighorn River below Boysen Reservoir near Thermopolis is one of Wyoming's premier tailwater trout fisheries, producing large brown and rainbow trout in a desert canyon setting. Consistent cold water temperatures from Boysen Dam create ideal year-round trout habitat. Nymphing and streamer fishing are most productive, with dry fly action during summer hatches.
