Late Summer Sizzle on the Big Horn

Artificial Lure reporting in from Big Horn, Montana, serving up today’s fishing scoop with a heavy dose of local flavor. It’s Wednesday, September 3rd, and we’ve hit the kind of late summer heat that bakes right through the cottonwoods. The mercury’s riding high—mid-80s by afternoon—and we’re seeing very little wind, just a hint of smoke in the air from the western fires. Sunrise rolled into the valley at 6:37 AM and sunset’s coming at 7:45 PM tonight, giving us a long, golden stretch for casting lines. Tide-wise, Big Horn River doesn’t run on ocean tides, but flow is crucial right now. The Montana snowpack’s flushed through, leaving us with clear, cold tailwater conditions—ideal for feeding rainbows and browns. Water temps are holding in the low 60s, and flows are steady, nothing blown out, just perfect for wading and drifting. Big Horn’s fishing is classic September: bug life slowing, but the trout are still fired up. Most action is happening subsurface—nymphing rigs dunked 6 feet down with tungsten tailwater sowbugs and pink Lite Brite Perdigons are pulling in chunky bows. Try the Little Green Machine and PMD Crackback for variety. Caddis and PMD hatches linger in the warmest hours, so keep an eye out for rising fish and have a PMD Sparkle Dun or X Caddis ready for a proper dry fly throw. Streamer bite woke up as water warmed; flash is king. Skiddish Smolt, Gold/Silver/Copper Kreelex, and the classic Mini Dungeon in olive or black have all hooked up. Slap them along grassy banks, especially where there’s a little chop. Early mornings and late evenings are your ticket—the trout are chasing and the river is quiet except for the birds. Recent catches? Locals have hauled in plenty of rainbow trout, running 16 to 20 inches, and a few solid browns, some tipping 22. Counts are healthy and, according to last night’s chat at the Two Leggins bar, a dozen or so landed by day’s end isn’t unusual if you know your seams. Hoppers are fading but don’t toss them yet; if fish are shy, switch to beetle or flying ant patterns—especially on the clearer stretches. Hot Spots? Give these a go: - **Bighorn Access at MPS**: Early morning streamer runs, good hatches near riffles. Perfect for waders wanting solitude. - **Afterbay to Three Mile Stretch**: Deep seams and healthy flows; nymphing rigs excel here, trout stack up on the edges. - **Crow Agency Bridge**: Often overlooked, solid trout right at the transition where big browns patrol. If you’re branching out, Fort Peck is seeing salmon deep right now—think 80 to 100 feet down, big bodies fighting hard. Spoons and dipsy divers rocking blue jack Brad’s cut bait are the winning ticket, based on the Captain’s weekend update. Not hot and heavy, but the salmon landed are monsters, all tipping past 19 lbs.
