Yes. This is a strong time to fish.
No clear best access mode. Wade and Float have the same top score. Use current access, footing, weather, and local rules to choose.

Wade and Float have the same top score. Use current access, footing, weather, and local rules to choose.
This report does not recommend bank fishing on this reach.
A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.

These notices match this river report. No notice here does not mean the river is open. Always check the agency before you fish.

What to know about this notice
This is a floating restriction caused by construction, not a fishing or heat closure; it applies only to the named reach.
The report includes lower Blackfoot water, but the construction restriction closes floating only on the named Weigh Station-to-I-90 reach.
Your plan
Today's Blackfoot River plan.
The Blackfoot can be a great freestone trout day, but it is also fast, cold, and sensitive. Use the Bonner gauge, check current FWP restrictions, and match your plan to access rules before fishing.
- Check first
- Use the Bonner gauge for the lower-river trend and do not wade heavy mid-channel current during runoff.
- Try
- Fish banks and inside seams first after runoff. Trout often avoid the heaviest current.
- Leave when
- Skip or pivot when FWP restrictions are active for your timing, water temperature is unsafe, runoff is pushy, area access or camping rules are unclear, or native-fish handling would be poor.

How to fish it
How to fish Blackfoot River today.
The best Blackfoot windows are stable post-runoff flows, cool mornings, and enough clarity for fish to use banks, riffles, and softer seams. Rising, muddy, hot, or restricted water should change the plan.
Post-runoff green
Fish stonefly dries, rubberlegs, and streamers tight to banks and soft current.
Clear summer flow
Use hoppers, ants, caddis, and dry-droppers around shade and riffle edges.
High or muddy
Stay near soft edges only if safe, or wait for the river to drop and clear.
Warm low water
Check FWP restrictions and fish early, or move to colder water 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
USGS shows 655 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1898-2025, 93 readings) show a typical middle range of 557 cfs to 874 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.
Mid to late summer: Hoppers, ants, beetles, and early starts matter; watch temperature closures.
USGS water temperature is about 66.2F, and the rolling 24-hour high did not trigger a heat caution. USGS marks the temperature data provisional and may revise it.
No active NWS alert was returned for this forecast point.
Skip or pivot when FWP restrictions are active for your timing, water temperature is unsafe, runoff is pushy, corridor access or camping rules are unclear, or native-fish handling would be poor.
Trip notes
Trip notes
Check these before you choose a reach.
Use RiverReports and USGS 12340000 near Bonner together. Dropping post-runoff water and cool stable mornings are the cleanest windows. High, muddy, or hot low water should move the plan to safer edges or a different river.
Skip or pivot when FWP restrictions are active for your timing, water temperature is unsafe, runoff is pushy, area access or camping rules are unclear, or native-fish handling would be poor.
Start with the Bonner gauge and the recreation-area plan. Then decide whether the day is a bank-focused dry-dropper float, a roadside wade session, or a short streamer window around clouds and clarity.
If the Blackfoot is high, warm, crowded, or restricted, compare Rock Creek for a wade-focused creek plan, the Clark Fork for larger Missoula water, or the Bitterroot for another freestone option.

Access and safety
Blackfoot 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 waterbody restrictions control seasons, harvest, methods, protected species, and heat-related closures. Check the current FWP pages before fishing.
Russell Gates to Johnsrud area
FWP identifies this as the managed Blackfoot River recreation area with special planning rules.
Bonner gauge reach
Primary flow reference for the lower Blackfoot and Missoula-area fishing plans.
Upper valley access
Use official sites and posted public land. Private ranch banks require permission.
Montana stream access does not let you cross posted private land to reach the water.
FWP area camping is limited to designated or permitted sites, so do not improvise camps on gravel bars.
Check current closures, hoot-owl restrictions, and fire or road conditions before committing to a float.

Quick answers
Quick Blackfoot River answers.
What should I check first before fishing the Blackfoot River?
Check the Bonner gauge, FWP current restrictions, water temperature, weather, and the area access plan.
Are there special fishing rules on the Blackfoot River?
Yes. Blackfoot rules include native-trout protections and section-by-section limits, so read the current FWP rules.
What flies should I bring for the Blackfoot 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 Blackfoot River?
Yes in many places, but flows are pushy and access is not continuous. Use official sites and stay within Montana stream-access rules.
When should I skip the Blackfoot 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.
