Bighorn River Fishing in August

Bighorn River Fly Fishing in August

Water temperatures stabilize in August, creating predictable angling scenarios from one day to another throughout the Bighorn River. Advanced anglers relish the shallow water sight fishing opportunities using dries or lightly weighted nymphs.

Terrestrial fly patterns and dry/dropper rigs are go-to setups as the sun rises high in the August sky. Large hoppers with small, heavily weighted nymphs work well along deep seams and at the bottom of long riffles. As the floating grass starts to become an issue, many anglers prefer to fly fish with a single dry.

Anglers fishing the Bighorn River in August should anticipate increasing growth of troublesome aquatic vegetation during the heat of the summer. Experienced Montana fishing guides can help anglers with a variety of techniques to efficiently clean their flies. The floating grass is annoying for anglers but does not affect the trout’s willingness to eat well-presented flies.

August Fly Fishing Hatches on the Bighorn River

PMDs, Yellow Sallies, and Caddis are the predominant hatches on the Bighorn River in August. Trico hatches start to appear in late August and last into the early weeks of October. Grasshoppers, ants, and beetles are all available to the wild trout in the river and have importance throughout the late summer.

Small bait fish will start to be present along the edges of banks and pocket water, creating excellent streamer fly fishing opportunities.

Bighorn River Fly Fishing Techniques in August

Long dry fly leaders and stealthy presentations will achieve the best results for the angler fishing the Bighorn River in August. Carefully planned approaches to rising trout will reward the patient angler.

When nymph fishing, use short leaders and focus on fast shallow water or deep drop-offs along cliff banks. Heavily weighted tungsten flies get down quickly to the deep trout feeding near the river’s bottom in the long, slow glides.

Bozeman Fly Fishing Guide Pro Tip:

August hatches of PMD and Trico mayflies can be prolific. During peak hatch periods, trout tend to selectively sip on emerging naturals rather than feed opportunistically on drifting hopper patterns. However, perseverance typically pays off for the angler who is willing to stick with the large, single dry with an explosive take from larger trout.
