Good fishing
Yes. Fishing looks good.
82
Good fishing based on the verified flow and weather. No official live water-temperature reading is available. Carry a thermometer during warm weather and stop if the water is stressful for trout.

Access choicesNo clear best mode
Wade, Bank / edge, and Float have the same top score. Use current access, footing, weather, and local rules to choose.
Bank / edge82/100
Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.
Float82/100
A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.
Your plan
Today's Clark Fork River plan.
This page focuses on the Clark Fork through and below Missoula. The river changes quickly after the Blackfoot, Bitterroot, and Rock Creek influences, so check the right gauge and current restrictions before choosing a reach.
- Check first
- Use the below-Missoula gauge for the main page flow trend and watch smaller stream clarity.
- Try
- Pick a reach first: town, below-town, or downstream float water each fishes differently.
- Leave when
- Skip or narrow the plan when FWP restrictions are active, smaller stream color makes the reach unreadable, heat compromises trout handling, or parking and legal river entry are unclear.

How to fish it
How to fish Clark Fork River today.
The Clark Fork is best when flows are stable, clarity is improving, and temperatures stay trout-safe. If the river is big, brown, or warm, move to safer edges or a colder nearby water.
Dropping post-runoff
Fish banks, side channels, soft riffles, rubberlegs, and streamers.
Clear summer flow
Use caddis, PMDs, hoppers, ants, and small droppers through riffles and banks.
Rising or stained
Fish edges only if safe and avoid wading pushy crossings.
Warm low water
Check restrictions and switch to early mornings or another river if trout are stressed.
Fishing words used on this page
- U.S. Geological Survey (USGS) gauge
- A USGS gauge is an official river station that measures flow or water height.
- Cubic feet per second (cfs)
- Cubic feet per second, or cfs, shows how much water passes the gauge each second.
- Nymph
- A nymph is a young water insect. Anglers also use the word for a fly that copies it.
- Riffle
- A riffle is shallow, fast water broken by rocks.
- Seam
- A seam is the line where fast and slow water meet.
- Blue-winged olive (BWO)
- Blue-winged olives, or BWOs, are small mayflies that often hatch in cool or cloudy weather.
- Caddis
- Caddis are small water insects. The adults look a little like tiny moths.
- Dry-dropper
- A dry-dropper rig has a floating fly with an underwater fly tied below it.
- Emerger
- An emerger copies an insect as it rises from below the water toward the surface.
- Midge
- Midges are tiny flies and a common trout food, especially in cold water.
Why this call
Why this score
Short-term weatherUse caution
The forecast has storm or heavy-precipitation risk, so timing and access matter more than the score alone.
FlowHelps
USGS shows 1,850 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1930-2024, 95 readings) show a typical middle range of 1,460 cfs to 2,640 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.
SeasonHelps
Summer: Hoppers, ants, caddis, and evening riffles matter, with temperature checks.
WeatherHelps
The current NWS air forecast is about 81F, and the next 24-hour high reaches about 84F. Chance Showers And Thunderstorms.
Public alertsHelps
No active NWS alert was returned for this forecast point.
Trip notes
Trip notes
Check these before you choose a reach.
Use RiverReports and USGS 12353000 below Missoula together. Stable or dropping flow with improving clarity is the better window. Big, brown, rising, or warm water should push the plan to softer banks or another river.
Skip or narrow the plan when FWP restrictions are active, smaller stream color makes the reach unreadable, heat compromises trout handling, or parking and legal river entry are unclear.
Start by choosing town water, below-town water, or a downstream float. Match flies and safety to that reach instead of applying one Clark Fork plan to the whole drainage.
If the Clark Fork is high, dirty, warm, or crowded, compare the Blackfoot for colder freestone water, the Bitterroot for a valley hatch plan, or Rock Creek for a more wade-focused day.

Access and safety
Clark Fork River access and rules.
Use these places as starting points. Open the access link below and check posted signs before you park or enter. Montana FWP rules and current restrictions control trout, pike, harvest, methods, closures, and temperature-related limits. Check the current rules for the exact reach.
Missoula town reach
Good for quick access, but still requires current, temperature, and courtesy checks.
Below Missoula gauge reach
Primary page flow context after major smaller stream influence.
Alberton area
More float- and safety-focused. Do not treat it like simple wade water.
Montana stream access allows use below ordinary high-water marks, but it does not grant access across private land.
Bridge and town access can be crowded. Park legally and avoid cutting banks or trespassing.
Check current FWP restrictions and fish-consumption guidance before keeping fish from Clark Fork drainage reaches.

Quick answers
Quick Clark Fork River answers.
What should I check first before fishing the Clark Fork River?
Check the below-Missoula gauge, clarity, FWP current restrictions, weather, and your exact access point.
Are there special fishing rules on the Clark Fork River?
Yes. The Clark Fork has section-by-section rules and current restrictions can change during heat, fire, or emergency events.
What flies should I bring for the Clark Fork River?
Bring the hatch-chart flies, a few confidence nymphs, and a streamer box. Then adjust for water temperature, clarity, and the insects you actually see.
Can I wade the Clark Fork River?
Yes around some public access, but the river is large and pushy. Use official access and avoid crossing private land.
When should I skip the Clark Fork River?
Skip it when flows are unsafe, temperatures stress trout, wildfire or emergency closures are active, or legal access for the reach is not clear.
