The Four Seasons Of Fly Fishing The Bighorn River
The Bighorn River is known for its cool, clear waters coming in off the Yellowstone. Located in Montana and Wyoming, it is home to a thriving trout population. With nutrient-rich waters and an abundance of crustaceans and mayflies, both rainbow and brown trout flourish in population and grow to above-average size.
The Bighorn has earned its reputation as a legendary fly fishing river, drawing an unprecedented number of anglers all four seasons of the year. The various hatch cycles of native flies keep the trout well-fed, providing a unique year-round opportunity for fly fishing on the Bighorn River.
Recommended techniques vary from season to season. The three most commonly used include Dry Fly, Nymph, and Streamer. Dry Fly fishing imitates flies that land atop the water where the trout feed. The Nymph method utilizes lures below the surface, much like the insect larva that hatch from eggs on the river floor. Streamer fishing also uses a submerged fly, but one that looks like a small fish.
Spring
From mid-March to mid-May, the Bighorn River is at some of its lowest temperatures. This is an excellent time for nymphing. Trout are more likely to be found in deeper channels at this time of year, so boat rentals are recommended. Midge and Baetis flies hatch during the spring months, making nymph flies ideal.
Summer
Summer months vary depending on river flow. All fly fishing techniques can be used throughout this season, though dry fly is best in July. In August, the flow is usually lower with warmer temperatures, making early morning and evening fishing productive. Hatches are less prevalent, but the neighboring farmlands bring in the terrestrials. These insects become more active as afternoon temperatures rise, allowing for some midday fly fishing success.
Autumn
September through November is the ideal season for dry fly fishing enthusiasts, as well as being optimal for streamer fishing. Summer tourist crowds dissipate, making for a more peaceful experience. Most of the heavy moss in September has disappeared by October, which can make this middle month more desirable.
Winter
Winter fly fishing on the Bighorn has become more popular in recent years. Streamer fishing really hits its stride in November when the Baetis flies hatch. Anglers are advised to prepare with appropriate winter attire as temperatures drop and snowfall may occur.
There are many fly fishing lodges on the Bighorn River for the ideal fly fishing experience. For more information, reach out to a local program, such as Montana Fly Fisher.
