Jeramie Prine's Tip of the Week

The Bighorn River is fishing well right now! Trout have wintered well and it is a promising sign for this season. Vary techniques from nymphing, dry fly fishing (dry/droppers), and streamer fishing. Fish all the water from shallow to deep. Summertime fishing is here! Streamers, nymphs, and dry flies are working right now. The biggest tip of the week is to keep those flies clean in between casts.

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.
