Bighorn River Early Summer: Strong Rainbows, Perfect Wade Flows, and Prime Fishing Windows

This is Artificial Lure with your Big Horn country fishing report around Bighorn, Montana. We don’t worry about tides out here – this is all about river flows, water temps, and weather on the Bighorn River below Yellowtail. Flows this time of year typically run in that comfortable wade‑able range out of Yellowtail Dam, with clear, cold water and steady levels. Boaters are drifting fine from Afterbay down through Three Mile, and wade anglers are doing well around the classic side channels and gravel bars. Weather-wise, expect a classic early‑summer mix: cool, calm mornings, a bit of breeze building through midday, then warmer, sometimes breezy afternoons, with a chance of a garden‑variety thunderstorm rolling through late. Sunrise is early and sunset is late, giving you a long fishing window. Think first light to about 11 a.m., then again the last three hours of daylight for the best bite. Fish activity has been strong. Rainbows and browns are feeding hard in the riffles and along the seams. Mornings have seen good subsurface action with nymphs and soft hackles, and when the clouds hang around, you can still find noses in the softer eddies. Midday gets a little tougher and more technical, but folks who downsize and lengthen leaders are still putting fish in the net. Recent trips have reported plenty of healthy 14–18 inch rainbows with a good mix of browns, and the occasional bigger fish pushing the low‑20‑inch mark. Numbers have been solid: good boats are putting a couple dozen fish over the side in a full day, with wade anglers picking off steady singles and doubles if they stick to productive runs and keep moving. Best “artificial lure” options right now are small, natural‑colored patterns. For fly anglers, that means: - Nymphs: sowbug and scud patterns in gray and tan, small mayfly nymphs, and midges under an indicator. - Dry flies: slim mayfly patterns and small caddis dries when you see consistent rising. - Streamers: olive, black, or brown buggers and articulated patterns swung or stripped tight to the banks early and late. For conventional gear, think light line and subtle offerings: - Small inline spinners in gold or copper. - Tiny crankbaits that mimic sculpin and juvenile trout. - If you’re allowed and inclined to bait fish in nearby stillwaters, nightcrawlers and minnows on light tackle will still turn heads. A couple of local hot spots to keep in mind: - The classic stretch from Afterbay to Three Mile: great structure, side channels, and plenty of cold, oxygenated water. - Downstream runs around Bighorn Access and beyond: less pressure than the upper river and some sneaky good banks, especially in the evening when fish slide shallow. Work the seams, keep your drifts clean, and don’t be afraid to change up size or pattern if you’re not getting looks. The fish are there and they’re eating; it’s all about matching mood and light.
