Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.

Not today. Make another plan.
Best option: Float. A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

Your plan
Today's Rock Creek plan.
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.
- 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.

How to fish it
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.
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
An active alert is in effect: Red Flag Warning issued August 22 at 9:08AM MDT until August 23 at 8:00PM MDT by NWS Missoula MT. Check public safety sources before going.
Float: A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.
The forecast has storm or heavy-precipitation risk, so timing and access matter more than the score alone.
USGS shows 276 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 typical middle range of 190 cfs to 348 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.
Summer: Terrestrials, caddis, and shaded dry-dropper fishing are practical.
Trip notes
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.
