Wade49/100
Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.

Best supported approachFloat
Compare wading, bank fishing, and floating before choosing how you will fish.
Bank / edgeNeed data
This report does not describe this as a primary mode. Verify legal access, depth, launches, and retreat options before planning around it.
Float · Best fit73/100
A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

How to fish it
A fork with its own flow and special-use planning.
The West Fork Bitterroot is not just a footnote to the main Bitterroot. It has a verified Conner gauge, Painted Rocks influence, and FWP special-use river permit rules that can affect float planning.
- Use the Conner gauge for current West Fork trend instead of guessing from the mainstem.
- FWP special-use river permit rules can affect commercial and nonresident float scheduling.
- Expect clear water, pocket water, and fast changes from storms or release patterns.
- Check current restrictions and temperature before fishing during summer heat.
Why the score looks this way
Public alertUse caution
An Air Quality Alert is active near this forecast point, so the score is capped at caution until smoke and access conditions are checked. NWS alert: Air Quality Alert issued August 2 at 9:12AM MDT by NWS Great Falls MT.
FlowHelps score
USGS shows 255 cfs with a stable over about 6 hours trend. Today's flow is within the normal seasonal range of 144 cfs to 292 cfs. Weather, water temperature, and access are the next checks.
SeasonHelps score
Early summer: Runoff drop brings stonefly, caddis, PMD, and dry-dropper fishing.
WeatherHelps score
The NWS forecast is about 71F with Areas Of Smoke.
Fishing usefulnessHelps score
Skip or pivot when special-use or access details do not fit the trip, FWP restrictions are active, low warm water threatens trout handling, or wood and flows make floating marginal.
Read the water
What changes the plan.
The West Fork fishes best when flows are stable, water is cool, and access or permit rules are clear. If flow is rising, warm, or crowded, use the main Bitterroot or East Fork plan as a backup.
Stable release or flow
Fish dry-droppers, stonefly nymphs, caddis, and soft seams.
Low clear water
Use longer leaders, smaller flies, shade, and careful wading.
Rising or stained
Fish protected edges only if safe or wait for clarity to return.
Warm summer water
Check restrictions, fish early, and stop if trout are stressed.
Your trip plan
Know when to go—and when to skip it.
Best flows
Use RiverReports and USGS 12342500 near Conner together. Stable cool water is the best platform for dry-dropper fishing; sudden release changes, low warm flows, or storm color should narrow the plan.
When to skip
Skip or pivot when special-use or access details do not fit the trip, FWP restrictions are active, low warm water threatens trout handling, or wood and flows make floating marginal.
Local plan
Start with the Conner flow, current restrictions, and one legal access pair. Then decide whether the day is a compact wade session, a short float, or a dry-dropper scout after releases stabilize.
Backup water
If the West Fork is low, warm, restricted, or access-complicated, compare the main Bitterroot for more room, the East Fork for small-water scouting, or Rock Creek for a stronger wade-focused public plan.
Hatches & flies
Bring a flexible box.
TimingWhat to watchUseful flies
March to AprilSkwalas, March Browns, BWOs, midges, and early stonefly movementSkwala dry, rubberleg, March Brown, BWO emerger, zebra midge
Fly family · report suggests “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 ↗
Fly family · report suggests “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
Fly pattern · report suggests “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 ↗
Fly pattern · report suggests “Pat's rubber legs”Pat's Rubber LegsThe core Pat's Rubber Legs architecture is a long weighted stonefly nymph with a chenille body, two rubber tails, a pair of antennae, and multiple long flexible legs. Pat Bennett's documented 1995 form used true-brown chenille and true-olive Super Floss; coffee-and-black became a familiar later guide treatment. Beads, jig hooks, thoraxes, wing cases, articulated bodies, white legs, and other colors are explicit variations—not silent parts of one universal recipe.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
Fly family · report suggests “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 ↗
Fly family · report suggests “beetle”Beetle PatternsBeetle flies range from simple foam shells to hair-bodied and sunken forms. A rounded back and compact profile distinguish the family from ants and hoppers.See family guide ↗+ 2 more reviewed guides in the Fly Box September to OctoberMahoganies, BWOs, October caddis, baitfish, fall streamer windowsMahogany, BWO, October caddis, sculpin, leech
Fly family · report suggests “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 ↗
Fly family · report suggests “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
Use the Conner gauge before deciding whether to wade, float, or move to the main Bitterroot.
02
Fish pocket water and bank seams with a dry-dropper when flows are clear and stable.
03
Use smaller dries and longer leaders in clear low water.
04
Streamer fish low light, slight stain, or deeper bends with a short stout leader.
05
Plan floats around FWP special-use rules and current restrictions.

Yes. West Fork and Bitterroot rules include reach-specific trout rules and special-use float planning.
What flies should I bring for the West Fork Bitterroot 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 West Fork Bitterroot River?+
Yes in legal public reaches, but access is mixed and flows can change. Use official sites and respect private land.
When should I skip the West Fork Bitterroot 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.
