Should I go fishing?
Go with caution.
Flow is high for this time of year.
Best option: Floating. A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

Why this recommendation?
USGS shows 331 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1973-2025, 53 readings) show a median near 264 cfs and the upper quartile near 311 cfs; today's flow is high for the date. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.

If you go
- Check first
- Use the Clinton gauge for lower Rock Creek trend and runoff timing.
- Try
- Move often and fish pocket water quickly with one or two good drifts per lane.
- Leave when
- Skip or pivot when runoff makes crossings unsafe, FWP restrictions are active, the canyon road or parking plan is poor, water is too warm for trout handling, or access would require pushing through private land.

Methods, fish species and trip notes
How to fish Rock Creek today.
Rock Creek is best when flows are dropping and clear enough for safe wading. Fish big stoneflies during the runoff edge, then shift to caddis, PMDs, terrestrials, and fall olives as water settles.
Runoff drop
Fish stonefly nymphs, big dries, and streamers in safe bank water.
Clear summer flow
Use caddis, PMDs, hoppers, ants, beetles, and light droppers.
Low and spooky
Go lighter, fish shade, and approach from downstream.
High or rough road
Postpone, fish safer edges, or choose a bigger access-friendly river.
Wading, bank fishing or floating?
Best access methodFloating
These scores compare the risks of wading, bank fishing, and floating.
Wading44/100
Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.
Bank fishingNot recommended
This report does not recommend bank fishing on this reach.
Floating · Best fit68/100
A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

Is Rock Creek worth the trip today? Check flow, weather, hatches, access, and rules for Montana before you go.
Rock Creek near Missoula is a famous wade fishery, but the flow, road, and FWP boat closure rules should guide the day. Do not confuse it with other Montana waters named Rock Creek.
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
FlowUse caution
USGS shows 331 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1973-2025, 53 readings) show a median near 264 cfs and the upper quartile near 311 cfs; today's flow is high for the date. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.
Best mode nowUse caution
Float: A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.
SeasonHelps
Fall: BWOs, October caddis, streamers, and fewer crowds make strong days.
Water temperatureHelps
USGS water temperature is about 57.6F, and the rolling 24-hour high did not trigger a heat caution. USGS marks the temperature data provisional and may revise it.
Public alertsHelps
No active NWS alert was returned for this forecast point.
Trip notes
Check these before you choose a reach.
Use RiverReports and USGS 12334510 near Clinton together. Dropping post-runoff water is the strongest window. High pushy water favors waiting, and low warm water should trigger temperature and restriction checks.
Skip or pivot when runoff makes crossings unsafe, FWP restrictions are active, the canyon road or parking plan is poor, water is too warm for trout handling, or access would require pushing through private land.
Start with the Clinton flow and one defined canyon access plan. Fish upstream carefully through pocket water, soft seams, and shaded banks instead of trying to cover every turnout.
If Rock Creek is high, crowded, warm, or road-limited, compare the Clark Fork for larger water, the Blackfoot for another freestone option, or Flint Creek for a smaller but more access-sensitive plan.

Before you go
Montana FWP rules include Rock Creek-specific artificial-lure, trout, and seasonal fishing-from-boat rules. Check current FWP rules and restrictions before fishing.
Where to access the river
Clinton lower creek
Primary gauge and lower-access planning area.
Rock Creek Road
Main access area with many public and private boundary considerations.
Lolo National Forest Rock Creek Area
Official forest access context for camping, roads, and recreation.
- Use public pullouts, campgrounds, and posted access. Do not assume all roadside banks are open.
- Rock Creek Road can be slow and rough. Leave time for travel and avoid blocking traffic.
- FWP boat and method rules are central to the Rock Creek plan, especially July through November.

Quick questions
What should I check first before fishing Rock Creek?
Check the Clinton gauge, Rock Creek Road conditions, FWP rules, current restrictions, and weather.
Are there special fishing rules on Rock Creek?
Yes. Rock Creek has important method and seasonal boat-fishing restrictions, so read the current FWP rules.
What flies should I bring for Rock Creek?
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 Rock Creek?
Yes, it is mostly wade-focused, but runoff and boulders can be serious. Use legal access and avoid private banks.
When should I skip Rock Creek?
Skip it when flows are unsafe, temperatures stress trout, wildfire or emergency closures are active, or legal access for the reach is not clear.
