Jeramie Prine's Tip of the Week

The Bighorn River is fishing well. The colder weather has the fish moving to different waters due to temperature change. It appears that the Brown Trout spawn is pretty much over, but we have noticed that winter spawning Rainbow Trout seem to be active. If you notice redds, please don't walk on them or target them for fishing. Nymphing and dry fly fishing (in right conditions) are working. Time to switch over to winter tailwater flies.

Description: About Bighorn River

The Bighorn River in Wyoming is an amazing fishery that can be fished year-round for big healthy Browns, Rainbows, and the occasional Cutthroat Trout. It definitely helps to fish this river from a drift boat as it is a large river, and there is limited and hard to reach public access. The Bighorn River boasts roughly 1100 trout per mile, and the scenery is not too bad either. The Bighorn River in Wyoming is similar to the stretch in Montana, but not nearly the amount of people the river sees up north. With that said, the Bighorn in Wyoming has been discovered and in the spring the river can get pretty busy. Winter can be a great time to fish the Bighorn with little to no crowds. In summer, anglers can count on moss but some great dry fly fishing. Fall can be a magical time on the river with cooler temps, less moss, and fish chasing streamers.
