Bighorn River Fishing Report: Excellent Nymphing, Solid Hatches, and Trophy Trout Opportunities
Published 11 months ago
Description
This is Artificial Lure with your Bighorn Montana fishing report for Friday, May 30, 2025.
We’re hitting that sweet spot on the Bighorn River right now. The weather is prime for anglers—mostly sunny skies are on tap, with patchy morning fog burning off early. Highs are headed for the lower 70s with a pleasant southeast breeze around 5 to 15 miles an hour, and overnight lows settling in the mid-40s. Sunrise was at 5:39 am and sunset will be at 8:29 pm, giving you a full, long day on the water. No tidal fluctuations around these parts—your peak bite will follow water temps and the light, with the afternoon warmth kicking up some extra fish activity.
River flows are consistent, holding near 2460 cubic feet per second, and the water is clear to lightly green with only a trace of grass. Afternoon water temperatures are running about 49 degrees. We’re seeing excellent insect activity and plenty of fish on the feed—reports are stacking up from guides and locals alike that browns and rainbows in the 16 to 20 inch range are being caught in good numbers, and a handful of hefty trout over 22 inches have turned up this week too.
Nymphing remains your best bet. Sowbugs and Baetis nymph imitations like Tailwater Sowbugs (sizes 14 to 16), Wonder Nymphs, and Flashback Quill Nymphs are hot right now. San Juan Worms and two-tone or orange scuds are also catching. Morning hours are perfect for small midge pupa, especially the #18 Tung Teaser. If you’re keen to chase the afternoon rises, bring some #20 Sipper Midges and CDC Midges, as well as Baetis dry patterns like Cripple Thors. For a change-up, streamer anglers are having luck with Sculpin patterns and Sparkle Minnows—try an articulated sculpin or Thin Mint for bigger browns willing to chase.
Drift boats are definitely the way to cover water, but there are still some productive wading spots, especially around Afterbay and 3 Mile. Two of the hottest stretches this week have been from Afterbay to 3 Mile, and down from 3 Mile to Bighorn Access—both loaded up with active fish and plenty of room to work nymph rigs deep and slow. Watch out for spawning rainbows along the reeds—give them a wide berth.
There’s been no significant rain in recent days, so clarity is excellent unless Soap Creek runs muddy after a stray shower—always worth a check before venturing downstream from the dam.
In terms of bait, stick to those proven river staples: cream and red midge larva (size 20–22), Black Micro Mayflies, Zebra Midges, and Pearl or Olive Jiggy Perdigons. Tie up a tandem rig with a midge larva and pupa, run it under an indicator, and keep it near the bottom for the best results.
Thanks for tuning in. Remember to subscribe for daily reports and tips, and tight lines out there—this is one of the best weeks of the season!
