Bighorn River Wyoming Fishing Report: Fishing on the Bighorn River is back to “Bighorn Good.” We had a great day with our friend Chad on Sunday. It looks like spring time is in the air with great fishing and more boats on the river. It was nice to see all of the couples floating and fishing together on Valentine’s Day. A family that plays together, stays together! The rainbow trout are starting to spawn and stage on their redds (spawning beds). Dunoir Fishing Adventures asks anglers coming to fish the Bighorn River to please not fish, wade, or walk across the redds found in shallow riffles in the white gravel patches. There are plenty of nice fish to be caught in the deep runs beneath the riffles without disturbing spawning fish. They are the future of keeping the Bighorn the fishery strong and healthy.
