Bighorn River Fishing Report Thermopolis, Wyoming
Bighorn River Fishing Report: Thermopolis, Wyoming; The Bighorn River water flows have recently bumped up to 3000 CFS in anticipation of spring runoff. There is only about 977 CFS flowing into Boysen Reservoir, so the Bureau of Reclamation is planning ahead. With not as much snowpack this year, the Bighorn River should not see the high water flows that we have seen in the past couple of seasons. We will see what the rest of spring brings too. We will keep you posted on any crazy weather or conditions that could pop up.
This weekend brought the first real blue wing olive hatch for the season. The dry fly fishing was the most productive with trout feeding on the surface actively. It is always a hoot to be fishing smaller dry flies so early in the season and there should only be more of the blue wing bite to come. Hot flies: annelids, eggs, midges, and blue wing olives.

Dunoir Fishing Adventure’s fishing guides have been working hard in Dubois and Thermopolis, Wyoming guiding on the alpine lakes and the Bighorn River. We are in our peak season for guests and making sure all of our guests have a fly fishing adventure of a lifetime. The fishing has remained good to great despite our big water on the rivers. Guests have been catching rainbows, cutthroats, browns, and even lake trout. Hot flies lately have been a few foam terrestrials, tricos, streamers, and baetis nymphs. It is the season of the dry-dropper set-ups! The Bighorn River flows have been bumped up to 3750 cfs yesterday, which is up from 2000 cfs a few weeks ago. My family and I enjoyed a day off at Brooks Lake fly fishing in Dubois a few days ago. Little Meesha is showing promise of becoming a great fly angler and is perfecting her cast. Keep posted for more fishing reports to come.
