Bank / edgeCheck
This report does not describe this as a primary mode. Verify legal access, depth, launches, and retreat options before planning around it.
Float96/100
A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.

River strategy
A wade-focused blue-ribbon creek with real rules.
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.
- Use the Clinton gauge for lower Rock Creek trend and runoff timing.
- FWP rules include artificial-lure and boat-fishing restrictions on key reaches and dates.
- Salmonflies and golden stones can draw crowds, so have a backup reach.
- Rock Creek Road can be rough, narrow, dusty, muddy, or slow depending on weather.
Why this score moved
FlowHelps score
USGS shows 625 cfs with a stable over about 6 hours trend. same-date USGS history (1973-2025, 53 readings) puts the normal middle range around 408 cfs-892 cfs. Flow is inside the same-date normal range, so weather, temperature, and access become the next checks.
SeasonHelps score
Early summer: Salmonflies, golden stones, caddis, and PMDs create the headline window.
Water temperatureHelps score
USGS water temperature is about 67F, with no heat stop triggered.
Public alertsHelps score
No active NWS alert was returned for this forecast point.
Fishing usefulnessHelps score
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.
Read the water
What changes the plan.
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.
Field plan
Fish it with intention.
Best flows
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.
When to skip
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.
Local plan
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.
Backup water
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.
Hatches & flies
Bring a flexible box.

Reviewed family · report says “Skwala dry”Skwala Stonefly PatternsSkwala is an insect and hatch label. Dark olive-brown nymphs and olive adult dries are materially different forms; seasonal timing also varies by watershed.See family guide ↗
Reviewed family · report says “rubberleg”Stonefly Nymph PatternsStonefly nymph patterns generally emphasize two tails, a broad thorax, segmented abdomen, and bottom contact; rubber legs, biots, beads, and jig hooks define different exact forms.See family guide ↗+ 3 more reviewed guides in the Fly Box May to JuneRunoff edges, salmonflies, golden stones, caddis, PMDsChubby Chernobyl, Pat's rubber legs, caddis pupa, PMD emerger, streamer
Reviewed pattern · report says “Chubby Chernobyl”Chubby ChernobylIdentify the construction, not the color: a long foam overbody over a segmented dubbed underside, rubber legs at two tie-in stations, two distinct buoyant synthetic-yarn wing sections, and a short flash tail. The paired wing stations and layered foam-and-dubbing body separate the reviewed Chubby from the original Chernobyl Ant and from generic foam hoppers or beetles.See photos & how to fish it ↗
Reviewed pattern · report says “Pat's rubber legs”Pat's Rubber LegsA weighted long-shank nymph, variegated chenille body, two tails, and multiple pairs of long rubber legs identify the core form. Generic rubber-leg stoneflies remain a broader family, not automatic Pat's Rubber Legs matches.See photos & how to fish it ↗+ 3 more reviewed guides in the Fly Box July to AugustHoppers, ants, beetles, nocturnal stones, spruce moths where presentHopper-dropper, foam ant, beetle, nocturnal stone, small perdigon
Reviewed family · report says “foam ant”Ant PatternsAnt patterns can be foam, fur-bodied, winged, or sunken. The narrow waist and paired body lobes matter more than one material recipe.See family guide ↗
Reviewed family · report says “beetle”Beetle PatternsBeetle flies range from simple foam shells to hair-bodied and sunken forms.

Reviewed family · report says “Mahogany”Isonychia and Mahogany Dun PatternsIsonychia nymphs are active swimmers; emergers, parachute or other dry forms, and spinners occupy different levels. Mahogany Dun can be regional hatch wording, so it does not identify one exact fly recipe.See family guide ↗
Reviewed family · report says “BWO”Blue-Winged Olive PatternsBWO describes a hatch group, not one fly. Nymph, emerger, dry, cripple, and spinner profiles must stay separate because they occupy different parts of the water column.See family guide ↗+ 3 more reviewed guides in the Fly Box 01
Move often and fish pocket water quickly with one or two good drifts per lane.
02
During salmonflies, fish banks, willows, and boulder edges before switching to smaller bugs.
03
Use a dry-dropper through riffles and a small streamer under clouds or stain.
04
Give other anglers room; popular roadside pools can get crowded quickly.
05
Do not fish from a boat during closed periods or where current FWP rules prohibit it.

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?+
