Blackfoot River Fly Fishing Report - January 1/4/2026
BLACKFOOT RIVER FLY FISHING REPORT
Western Montana — The Blackfoot
Report Date: January 4, 2026 | Next Update: January 11, 2026
Current River Conditions
Winter pattern: The Blackfoot is in its cold‑water, low‑flow behavior. Water clarity is excellent in most stretches, and trout are holding tight in deep runs and buckets. Expect selective fish and slow action; subsurface presentations will be the ticket.
Flows & Clarity
Flow Rate: Low for the season, generally stable (check USGS for current CFS before you launch)
Water Clarity: Very clear in mainstem reaches — sight fishing possible where trout are active

Water Temperature
Surface: Near freezing to mid‑30s °F (0–4°C) in early January
Trend: Cold and steady — fish metabolism is slow; short, accurate drifts win

Weather & River Access
Forecast: Cold daytime highs, below‑freezing nights; snow showers possible; variable wind on open stretches
Access: Winter road conditions can change quickly — dress for deep snow and icy banks; traction and ice cleats recommended

Regulations & Closures
Note: A seasonal drought-related restriction is in effect on portions of the North Fork (check Montana FWP and local reporting). Always verify boundaries and recent emergency closures before heading out.

Where the Fish Are
| Location | Likely Holds | Why |
|---|---|---|
| Deep main‑channel buckets & inside corners | Large rainbows, browns | Fish conserve energy in deep seams and ambush current lines |
| Soft drop‑offs below runs | Westslope cutthroat, resident trout | Reduced flow concentrates food; fish sit near the bottom |
| Undercut banks & log jams | All species — opportunistic takes | Cover + current breaks attract territorial anglers and trout alike |
| Shallow riffles (warmer pockets on mild afternoons) | Occasional selective rising fish | Small midge or BWO activity can trigger short dry‑fly windows |
Hatch Chart & Insect Activity (early January)
| Insect | Size | Activity Level | Prime Time |
|---|---|---|---|
| Midges (dominant winter food) | #18–24 | Light to moderate | Warmest hours of the day — short windows |
| BWO / Baetis | #18–22 | Occasional, very selective | Midday on mild, sunny spells |
| Caddis (scant) | #16–20 | Very light | Warm afternoons / near structure |
| Stoneflies / Salmonflies | Not active (winter) | None | N/A |
Recommended Flies
I’ve grouped choices by presentation — winter fish want something that reaches the food or convincingly matches tiny midges and baetis emergers. Below are field‑tested go‑to patterns and direct links so you can order or reference photos.
Nymphs (primary tactic)
- Egan's Poacher - Olive — excellent euro/anchor style nymph for getting to the bottom in slow winter buckets.
- Egan's Thread Frenchie Jig - Olive — a compact jig nymph that fishes tight on the bottom and reads subtle takes well.
- Tungsten Dart - Red — a dense attractor that helps drop your setup into deep lies fast.
- Pheasant Tail Tungsten — classic mayfly nymph profile, great as an indicator or dropper when fish key on baetis or small emergers.
Dry Flies & Emergers (opportunistic windows)
- Parachute - Blue Wing Olive — slim, visible emerger/dry for brief BWO pulses.
- Stealth Link Mercer - PMD — an understated emerger/dry that reads perfectly in clear winter water.
- Top Secret Midge — go‑to when fish are keyed on tiny midges; use small sizes and precise drifts.
- Antonio's Adult BWO — slender adult pattern for picky rises on mild afternoons.
Streamers (when you want meat — slow and methodical)
- Coffey's CH Sparkle Minnow Sculpin — a compact sculpin imitation for deep pools and tailouts.
- Sculpzilla - Olive — articulated/large profile for heavier takes in winter lies.
- Galloup's Slick Willy - Whitefish — paddles and profile that trigger aggressive winter strikes.
- Near Nuff Sculpin - Olive — realistic profile for deep cover and undercuts.
Tactics & Tips
- Nymphing is the workhorse now: short leaders, tungsten or jigs on the point, and lighter droppers (PTs/baetis nymphs) above. Tight contact and split‑shot or tungsten will get your fly where the trout are holding.
- Euro/indicator rigs: tightline or euro nymphing will outfish long indicator rigs in heavy current pockets; indicators are still useful for quick, long drifts in clearer, slower runs.
- Streamer strategy: slow strips, long pauses, and focusing on deep seams, pocket water behind boulders and logjams. Fish will often eat a slow, beefy presentation in winter when they want a big meal.
- Dry fly windows are short: if you see rises, downsize and be patient — fish are selective. Tiny midges and BWOs will be taken in brief mid‑day warming periods.
- Safety & logistics: winter wading is hazardous. Wear a wading staff, ice cleats, and layered, waterproof clothing. Let someone know your put‑in/take‑out. Park responsibly and watch for drifting ice.
