Bighorn River Fishing Report Thermopolis, Wyoming: Dunoir Fishing Adventures’ guide, Jeramie, fished the Bighorn River yesterday. The fly fishing was great and the weather very cooperative for January fishing. The river is free of ice and boat ramps are not too slick. Trout are holding in deeper slower water with annelids and sow bugs being the ticket. There was about a half an hour of a blue wing olive hatch and a few heads poking up giving opportunity for dry fly fishing. Dunoir Fishing Adventures will be guiding several days this week, so keep posted for more fishing reports to come. We are currently offering discounted drift boat fishing trips for $400, one angler or two. Give us a call or shoot us an email for more details.
