Big Horn Montana Fishing Report Today

Name’s Artificial Lure, checking in with your Big Horn country fishing report for the Bighorn River around Fort Smith and down toward Hardin.

We don’t worry about tides out here—Bighorn’s a tailwater, not salt—but we do live and die by flows and weather. According to the Bureau of Reclamation gauges below Yellowtail, flows are running on the low, steady winter side, keeping that classic Bighorn green-olive tint and good clarity. With stable water and short days, the fish are settled into winter slots and feeding in predictable windows.

Weather-wise, the National Weather Service is calling for a cold, mostly clear day in the valley: morning temps in the teens warming into the upper 20s to low 30s, light wind compared to our usual Big Horn breeze, and only a slight chance of flurries later. That means decent comfort if you layer right and great conditions for midge hatches. Sunrise is right around 7:40 a.m., sunset close to 4:25 p.m., so your real prime window is late morning through mid‑afternoon when that water bumps a degree or two.

Montana Outdoor’s early‑December trout report has been saying southwest Montana tailwaters are fishing surprisingly well for winter, and the Bighorn is no exception. Local shop talk in Fort Smith is that the river has kicked out good numbers of chunky browns and rainbows in the 14–18 inch class this past week, with the occasional 20‑plus inch bow coming from deeper winter holes. Anglers running nymph rigs have been seeing steady action—nothing fast and furious, but a nice, consistent pick all day if you stay on the good water.

Fish activity is classic winter: slower in the first couple hours of light, then a nice ramp‑up once the sun hits the canyon walls. You’ll see midges getting going late morning, and on the softer inside seams there have been pods of fish rising in that one‑to‑three‑o’clock window when the air calms down.

Best producers right now:

- Nymphs: small is king. Zebra midges, black or red, in sizes 18–22; Ray Charles and soft hackle sowbugs in tan or gray; tiny olive or brown mayfly patterns like Tailwater Tiny or Juju Baetis in 18–20. Run a double‑nymph rig under an indicator with enough split shot to tick bottom, 5X to the top fly, 6X to the dropper.

- Dry flies: when noses show, go with a size 20–22 griffith’s gnat, CDC midge cluster, or a simple black parachute midge on long, fine tippet. You won’t get numbers on top, but you’ll get some of your better fish.

- Streamers: for those who like to move and cover bank lines, small articulated patterns in olive, tan, or black have taken some heavy browns in the low light. Think Thin Mints, small Sparkle Minnows, or a scaled‑down Sex Dungeon. Fish them slow—short strips and long pauses.

If you’re bait fishing on the reservoirs or slower side channels where it’s legal, think winter mode: nightcrawlers and leeches fished dead‑slow on the bottom. Perch and the odd walleye out of nearby stillwaters will still chew on a small jig tipped with a minnow.

Name’s Artificial Lure, checking in with your Big Horn country fishing report from just east of the mountains.

Out here around Bighorn and Hardin we don’t worry about tides, just flows and weather. The Big Horn River below Yellowtail is running clear and cold in full winter mode. Daytime highs are topping out in the 20s and low 30s with single‑digit nights, and a light north breeze is making it feel sharper on the fingers. According to the latest Southwest Montana trout outlook from Montana Outdoor, most rivers are sitting in that 34–38° range, and the Big Horn’s right in line with that tailwater pattern. Expect a narrow bite window late morning through mid‑afternoon when the sun finally gets on the water.

Sun’s creeping up late and dropping early now, so plan your casts around the warmest part of the day. Figure on fishing about 10:30 to 3:00 for the best shot at active trout. Outside that window, they’re glued to the bottom and not moving far.

Recent action has been classic winter tailwater stuff. Local shop chatter in Fort Smith has folks seeing steady numbers of 12–16 inch rainbows with a few thick browns pushing 20 inches coming out of the deeper runs. Nobody’s putting up crazy numbers, but patient nymphers are scratching out a dozen fish on good afternoons. Browns are mostly done spawning; they’re tired and hanging in the softest seams.

Best producers right now are small nymphs dead‑drifted slow:

- Zebra midges in black or red, size 18–22

- Tiny WD‑40s and RS2‑style emergers

- Skinny Perdigon patterns and soft‑hackle pheasant tails

Run them under a small indicator with enough split shot to tick bottom. Takes are subtle – that indicator just pauses or tilts. If it looks weird, set.

For the gear guys, slow is the name of the game. Thread‑fin minnow‑style jigs, small marabou jigs in black or olive, or a plain hook with a bit of nightcrawler or red worm will all work if you keep them crawling along the bottom. Folks soaking bait near town have picked up some eater‑size trout and the odd ling (burbot) when they stay past dark.

Fly anglers still wanting to look up can watch for midges between noon and two when the breeze lays down. A Griffith’s Gnat or small midge cluster in 18–22 over gentle back‑eddies will pick off a few picky risers.

Couple of local hot spots to circle:

- The big, slow bends and shelves just below Afterbay to 3‑Mile: classic wintering water with pods of rainbows stacked deep.

- The runs and tailouts around Bighorn Access and down toward Mallards: softer inside seams and long glides holding mixed browns and bows.

General rule right now: fish the water that looks “too slow” for summer. If you’re wading, watch those shelf ice edges – they’ll crumble out from under you. Keep guides de‑iced and fish barbless if you can; these winter fish don’t need extra handling.

That’s the word from Big Horn country. Thanks for tuning in, and don’t forget to subscribe so you don’t miss the next report.

This has been a quiet plea

Name’s Artificial Lure, checking in from along the Bighorn around Fort Smith and down toward Hardin, where winter fishing has the river mostly to ourselves.

We don’t worry about tides here, just dam releases. Yellowtail’s been running steady with moderate flows according to the Bureau of Reclamation, so the river is very wadable with plenty of soft seams and walking-speed current. Overnight lows are in the teens, daytime highs crawling into the upper 20s with a light north breeze, and a mix of high clouds and sun per the National Weather Service in Billings. Sunrise came in right around 7:40 a.m., with sunset about 4:25 p.m., so you’ve got a tight mid‑day window when things really wake up.

Fish activity is classic early‑winter Bighorn: slow at first light, then building from late morning through mid‑afternoon once that thin ice burns off the guides. Montana Outdoor’s statewide report yesterday notes that midges and small nymphs are the main ticket across our rivers, and the Bighorn’s right in step with that. Expect trout parked in deeper, softer buckets and along gravel transitions, not up in the riffle heads.

Recent catches have been strong for numbers, a little tougher for true hogs. Local shop chatter out of Fort Smith has folks boating good mixes of 12–16 inch browns and rainbows, with enough 18–20s to keep you honest. Anglers running nymph rigs from Afterbay to Bighorn Access are talking 20–30 fish days when they stick to the program: tiny bugs, long leaders, dead‑drifted perfectly. A few lake‑fat rainbows in the high teens have come from slower inside bends below 3‑Mile, mostly on scuds and sowbugs.

Best producers right now are:

- Tiny **midges**: zebra midges and black or gray pupae in sizes 18–22.

- **Scuds and sowbugs** in light gray, tan, and pink, size 14–18.

- **Baetis‑style nymphs**: slim olive or brown patterns in 18–20.

- For meat hunters, small **streamers** like olive or black woolly buggers and thin sculpin patterns, swung slow off the shelves.

If you’re throwing hardware, think subtle and slow: 1/8‑oz marabou jigs in olive or black, or small gold and copper spoons worked just off bottom. For bait where it’s legal and you’re not on the catch‑and‑release stretches, drifted nightcrawlers and salmon eggs in the deeper slots will still move fish, but most locals stick to artificials on this river.

Couple of hot spots to key on today:

- **Afterbay to 3‑Mile**: winter staple. Focus on the walking‑pace water below the obvious riffles and the inside bends with knee‑ to thigh‑deep depth. Long, light nymph rigs with a scud or sowbug anchor and a midge dropper about 14 inches below have been the bread and butter.

- **Between 3‑Mile and Bighorn Access**: fewer folks, colder vibe, but some of the better browns lately. Look for deep green buckets on outside bends. Drift nymphs first, then come back through with a small olive streamer swung low and slow. Many of the nicer browns have come tight right at the end of the swing.

Mid‑day i

Name’s Artificial Lure, checking in with your Big Horn country fishing rundown.

Out here around Bighorn and Hardin, the **Bighorn River** below Yellowtail is still the main game. No tides to worry about this far inland, just river flows and weather. The National Weather Service Billings office has us much cooler with highs in the 60s, northwest winds 10–20, and on‑and‑off rain showers most of the day. That cloud cover and chop on the water are just what we like for trout pushing shallow and feeding longer.

Sun’s coming up about 7:35 a.m. and ducking out near 4:25 p.m., so your best bite windows are first light to about 10 a.m., then a late push from roughly 2:30 to dark. That afternoon breeze will stack bugs and food along the soft edges and inside bends.

Local shop chatter this week has rainbows and browns in the **14–18 inch** class being pretty steady, with a fair number of smaller cookie‑cutters and a few browns sliding over 20 for folks who put in the time. Most boats are talking **dozens of fish a day** when they dial the pattern, especially on the upper three miles.

Trout have shifted into full late‑fall / early‑winter mode: hanging on the **drop‑offs below shelves, soft seams, and inside turns**, not blasting through the fast heads like summer. Nymph rigs are still king. Think:

- **Midges and baetis**: zebra midges, black or red in 18–20; small PTs and olive mayfly nymphs in 18.

- **Scuds and sowbugs**: tan or gray in sizes 14–16 riding point.

- Run them under an indicator with just enough weight to tick bottom every few drifts.

On the gear side, folks are doing well with **1/8–1/4 oz marabou jigs** in olive or black, small silver or gold **spinners**, and tiny crankbaits in brown trout or rainbow patterns. Keep retrieves slow and lazy; water temps are down and fish won’t sprint far.

If you’re set on streamers, keep it smaller and neutral: olive or white buggers, thin zonkers, or kreelex‑style flash flies. Swing them on a slow mend or a short strip right along the foam lines and the ledges. The bigger browns are still willing, just not chasing like October.

A couple local **hot spots**:

- **Afterbay to 3‑Mile**: Classic Bighorn water. The shelves and long inside bends are stacked with fish right now. Work every soft seam; don’t just race to the next run.

- **Bighorn Access to Mallards**: A touch less pressure, especially midweek. Deeper buckets and slower guts are fishing well for nymphs and jigs; good place to find that better‑than‑average brown.

No big bait‑bite reports like you’d see on a lake right now, but if you’re running conventional and it’s legal in your stretch, a **nightcrawler chunk on a light rig** drifted naturally through the slow stuff will still bend a rod.

Artificial Lure here with your Big Horn country fishing report, coming to you like a cup of hot gas-station coffee before first light on the river.

Around Big Horn, the air is running cold and crisp, with that steady early-winter pattern: mornings well below freezing, afternoons nudging up just enough to soften guides but not enough to shed a jacket. Expect light to moderate winds funneling down the valley, with a few passing snow showers possible and heavier snow stacking up in the surrounding Bighorn and Beartooth high country. Sunrise is roughly in that 7:30 window, with dusk settling in just after 4:30, so it’s a short fishing day and the prime window is late morning through midafternoon when the water and bugs both wake up a bit.

No tides to worry about here, of course; this is all river current and reservoir draw, and flows have been typical for early December—on the low and clear side on the Bighorn River below Yellowtail, with slow, deep wintering holes setting up nicely. Fish activity has shifted fully to winter mode: shorter bite windows but very consistent if you’re in the right lane and ticking bottom. Recent reports from local regulars and shop talk around the Big Horn and Fort Smith area have had anglers into solid numbers of trout—good pods of 14–18 inch rainbows with some browns mixed in, plus the occasional bigger brown in the deep bends. Numbers are still there if you stay patient and fish methodically; think a dozen-plus fish days for folks who stick with it and fish slow.

Best producers have been nymph rigs and tiny stuff. Small sowbugs, scuds, and midges in the 18–22 range under an indicator or tight-line setup are the bread and butter right now, with a split shot or two to get you down and a subtle yarn or small plastic indicator. A gray or tan sowbug followed by a black, olive, or red midge has been a classic combo. On overcast stretches, streamers are worth a swing—think small to medium sculpin or leech patterns in olive, black, or rust, fished low and slow off the bank drops and along ledge rock. Gear anglers are doing best with light jigs tipped with soft plastics or a bit of worm, and small silver or gold spoons crawled through deeper runs.

For bait, if you’re on still water or legal bait stretches nearby, nightcrawlers and minnows on slip rigs off the deeper points are pulling the occasional trout and walleye from local reservoirs and slower side water. Scented soft baits in natural colors can stand in where live bait isn’t allowed. Think subtle, natural, and slow; the fish are not looking to chase far right now.

A couple of hot spots to put on the list: the classic Bighorn River sections just below Afterbay Dam down through the first few miles remain the most reliable, with long, even runs and deep shelves loaded with wintering rainbows. Farther downstream, the bends and deeper slots around the 3-Mile to 13-Mile stretches can fish a little quieter pressure-wise but produce some of the better brown trout, especial

Well folks, this is Artificial Lure coming to you with today's Big Horn fishing report for Thursday, December 4th, 2025.

We're in the heart of winter fishing season here in Montana, and conditions are shaping up pretty decently. Looking at the weather today, we're expecting mostly cloudy conditions with highs in the 20s and 30s across the region. Not too brutal for December, so bundle up and get out there.

Now, let me tell you what's been happening on the water. The Upper Salmon River upstream of the Middle Fork has been putting on a show lately. Anglers are averaging about 9 hours per steelhead caught up there, which is solid winter fishing. The river's flowing at good levels right now—flowing at around 1,060 cfs at Salmon, ID, which is 86% of average for this time of year. Water temps have dropped down to around 35 degrees Fahrenheit, so your steelhead are going to be sluggish but feeding.

For tackle, you'll want to focus on deep presentations. Think heavy spoons and jigs in silver and chartreuse colors—those pop in the cold, dark water. Live bait like fresh shiners or roe works fantastic this time of year too. The fish are concentrated in deeper holes, so don't waste time in the shallows.

If you're looking for hot spots, focus your efforts downstream of North Fork on the Upper Salmon, and definitely don't overlook the areas upstream of the Lemhi River. Bank fishing has been your best bet with boat numbers staying low this week.

One heads up—this might be the last steelhead update for 2025 from the local reports, with fishing effort expected to pick back up come spring.

# Big Horn Montana Fishing Report - December 3rd, 2025

Well folks, this is Artificial Lure coming to you with today's Big Horn fishing report. We've got some challenging conditions out there, but if you know where to look, there's still opportunity.

Let's start with the weather. We're expecting a chance of morning snow in some areas with partly to mostly sunny skies throughout much of the day. Highs reaching into the low 20s to low 30s, with lows dropping into the single digits and teens overnight. Bundle up out there.

For sunrise and sunset, we're looking at about 7:30 AM rise and roughly 4:45 PM set, so you've got a pretty short window to work with today.

Now, here's the real talk about fishing the Big Horn right now. We're in that tough winter phase where the water temps are dropping fast. Trout are sliding into the deeper slots and runs where they can conserve energy. Nymphing is your best bet if you're targeting these fish. The water's running a bit low, which actually concentrates the fish, so focus on those deeper pockets.

As for what's been working recently, reports from across Montana show that fly anglers are having decent success with sink-tip lines. If you're a conventional angler, CAL jigs with shad tails and jerk worms are producing. Don't overlook small minnow imitations either—they're effective this time of year.

For hot spots on the Big Horn, focus on the deeper holes and slots below the dam. The current breaks near the canyon walls are also holding fish right now. These spots offer slightly warmer water and better oxygenation.

The fishing will be tough for most of winter with ice shelves forming, so patience is key. But those dedicated anglers who put in the time and focus on deep-water presentations will find hungry trout.

# Big Horn Montana Fishing Report — December 2nd, 2025

Well folks, it's your friend Artificial Lure coming to you on this early December morning here in the Big Horn country, and let me tell you, we're sitting in that sweet spot where late fall fishing is still firing on all cylinders before winter really clamps down.

We've had some genuinely fantastic conditions these past few weeks. Warmer than average temperatures mixed with overcast skies have kept the Yellowstone River and our local spring creeks very fishable. The Gardner River's been active too. That bonus round of fishing we've been enjoying isn't quite over yet—there's still time to get out there before things freeze up solid.

Here's what's been happening on the water. Nymphing has been solid, especially during that noon to 2:30 window when things heat up. You don't need to be out at first light fighting the cold—save yourself the misery. Start deep with a little weight and work your way up, targeting those slower pockets and structure. A size 10 or 12 Prince Nymph has been a workhorse, and the Pheasant Tail in similar sizes is money. Don't sleep on the Psycho Prince either—it's been turning heads.

Now, the streamer bite? It's been lights out good. Anglers are hammering fish on articulated and single-hook streamers in the deep inside bends and tail-outs. Those big fish are keying on white, pale and bright yellow, olive, and black patterns. The deeper, slower water is where the real bruisers are living right now.

On the spring creeks, there's still some surface action with size 22 Baetis hatching after 11 AM, and midges throughout the day. As we roll into December proper, those Baetis hatches will peter out and midges become increasingly important.

For spots, get yourself to those slower, deeper pockets on the Yellowstone—they're holding quality fish. The Paradise Valley spring creeks are consistent producers too, especially if you've got the finesse tackle for those smaller dry flies.

One heads up: keep your wits about you out there. Air and water temps in late fall and winter mean hypothermia is a real risk. Have a plan, dress smart, and carry your safety gear.

# Big Horn Montana Fishing Report - Monday, December 1st, 2025

Hey folks, Artificial Lure here with your Monday morning fishing report from the Big Horn area.

Weather-wise, we're looking at mostly sunny skies today with highs reaching the mid-20s to upper 30s depending on where you're at. It'll be breezy in some spots, so bundle up and watch for wind gusts, especially if you're out on the water. According to the National Weather Service, the Northern Big Horn area is expecting patchy fog this morning, so give yourself some extra time getting to your favorite spots.

Now let's talk water conditions. Montana's rivers are running a mixed bag right now. The Upper Mountain sections and various runs through the region are reporting runnable flows, which is solid for December. Stream flows across the state are experiencing varied conditions with some sections running below normal, but nothing that should keep you off the water entirely.

For today's fishing, focus on the classic winter patterns. Dark lures tend to work better in these shorter daylight hours—think black and purple soft plastics, deep-diving crankbaits, and streamers. If you're bait fishing, live shiners or sculpins will get the attention of hungry trout and walleye looking to bulk up before deeper winter sets in.

I'd recommend hitting the lower sections where the current is steady but manageable. The slightly warmer water near dam releases often holds concentrations of fish this time of year, and the breezy conditions should keep the sun glare minimal, making sight-fishing more productive.

Two solid spots to check out today: the river sections near established access points with deeper pools, and any areas where smaller tributaries feed into the main river—those transition zones concentrate fish.

# Big Horn Montana Fishing Report – November 30, 2025

Well folks, this is Artificial Lure coming to you on this chilly Sunday morning here in Big Horn country. We're looking at late fall conditions, and let me tell you, the fishing's still solid if you can handle the cold.

**Current Conditions & Timing**

Sunrise hit us around 7:45 this morning, and we'll lose daylight around 4:45 PM, so you've got a tight window to work with today. Water temps are dropping fast, which means the trout are more active early and late. The cold snap we've had is actually working in our favor – the rivers are holding fish in predictable zones rather than scattered all over.

**What's Been Biting**

According to the latest Montana Outdoor reports, late-fall fishing around here has been fantastic. The Madison and Yellowstone have seen some excellent streamer action as browns stage up for winter. On the Big Horn specifically, anglers are reporting solid success with both streamers and nymphs. The Mack Days competition on Flathead Lake just wrapped up with over 14,700 lake trout weighed in, which tells you the cold water has fish feeding hard right now.

**Best Presentations**

For the Big Horn right now, bring your streamer box – think black, olive, and brown patterns in 3 to 5-inch lengths. The fish are aggressive in November. If streamers aren't connecting, switch to larger nymphs and crawfish imitations. Live baitfish and crawdads work excellent if you're willing to wade slower sections. Don't overlook small leaches either – they've been producing consistently.

**Hot Spots**

The deeper runs below the dam are your best bet this time of year. Fish are holding in that slower, deeper water where temperatures stay more stable. Also work the outside bends where the current scours out deeper holes – that's where the bigger fish stack up in late fall.

**One More Thing**

This quiet period between hunting season and hard winter is absolutely prime. Most hunters have moved on, leaving the rivers peaceful and unpressured. If you can get out there, do it.
