Madison River looks fishable right now.
Current USGS flow is 296 cfs and has been stable for about 6 hours. Today's flow is unusually low for this date and below the usual low-water marker near 333 cfs. Low water can make fish spooky, warm, pressured, or concentrated; check temperature and handling risk.

Compare wading, bank fishing, and floating before choosing how you will fish.

How to fish it
Start with flow, temperature, and the section you plan to fish.
The upper Madison can fish very differently above Hebgen, below Quake Lake, and farther down the riffle water. Use the live flow chart first, then match the plan to wade safety, boat rules, and water temperature.
- Use the West Yellowstone gauge for the upper-river reference, then compare with downstream gauges if you plan to fish below Quake Lake.
- Expect strong current, slick rocks, and long riffle water. A wading staff is worth carrying.
- Dry-dropper, nymph, and streamer plans all have a place, but the best choice depends on flow and season.
- Check Montana FWP regulations and temporary restrictions before fishing, especially during warm summer weather.
Why the score looks this way
FlowUse caution
USGS shows 296 cfs with a stable over about 6 hours trend. Today's flow is unusually low for this date and below the usual low-water marker near 333 cfs. Low water can make fish spooky, warm, pressured, or concentrated; check temperature and handling risk.
SeasonHelps score
Early summer: A major hatch period with salmonflies, caddis, PMDs, and stonefly nymphs in play.
Water temperatureHelps score
USGS water temperature is about 63F, with no heat stop triggered.
Public alertsHelps score
No active NWS alert was returned for this forecast point.
Fishing usefulnessHelps score
Skip crossings when the river is pushy, when afternoon temperatures are stressing trout, when wind turns accurate presentations into guesswork, or when crowd pressure at the reach you chose would force sloppy wading around other anglers.
Read the water
What changes the plan.
The Madison rewards anglers who build the day around flows and water temperature. When the river is stable and cool, cover riffles methodically with dry-droppers, nymph rigs, and soft hackles. When flows rise or visibility drops, focus on protected edges and streamer water instead of forcing long mid-river wades.
Low and clear
Use longer leaders, smaller droppers, lighter tippet, and avoid walking through likely holding lanes.
Stable medium flow
This is the most flexible window for dry-dropper rigs, tight-line nymphs, soft hackles, and covering riffle edges.
High or pushy
Stay close to the bank, skip risky crossings, and fish inside bends, soft shelves, and streamer water near structure.
Warm afternoons
Carry a thermometer in summer. If water temperatures climb into stressful trout conditions, fish early, move to colder water where legal, or stop.
Your trip plan
Know when to go—and when to skip it.
Best flows
Use the West Yellowstone trend to frame the day, then match it to the section. Stable medium flows are the most forgiving for dry-droppers and nymphs; high pushy water should narrow you to edges, short drifts, and fewer crossing ideas.
When to skip
Skip crossings when the river is pushy, when afternoon temperatures are stressing trout, when wind turns accurate presentations into guesswork, or when crowd pressure at the reach you chose would force sloppy wading around other anglers.
Local plan
Split the day by section before leaving town: park-boundary and upper-river checks near West Yellowstone, classic fifty-mile-riffle decisions around Lyons Bridge and Raynolds Pass, then lower-valley alternatives only if your original section is too busy or too high.
Backup water
If the Madison is crowded, too warm, or blown out by wind, pivot to Hebgen Lake for a different style of day or to the Gallatin when you want a separate road-access freestone option.

TimingWhat to watchUseful flies
March to AprilMidges and blue-winged olivesZebra midges, RS2-style emergers, small pheasant tails, BWO dries
Fly pattern · report suggests “Zebra midges”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it ↗
Fly pattern · report suggests “small pheasant tails”Pheasant Tail NymphThe pilot page distinguishes the sparse original idea from the bulkier American form. Both use pheasant-tail fibers and copper wire, but bead heads, peacock-herl thoraxes, legs, flashbacks, jig hooks, and soft-hackle collars are variations that must be labeled.See photos & how to fish it ↗+ 2 more reviewed guides in the Fly Box May to JuneCaddis, PMDs, stoneflies, early salmonfliesElk hair caddis, PMD comparaduns, prince nymphs, stonefly nymphs
Fly pattern · report suggests “Elk hair caddis”Elk Hair CaddisLook for a tented elk- or deer-hair wing, clipped hair head, dubbed body, rib, and hackle palmered along the body. The body color should be labeled because tiers often match different natural caddis colors.See photos & how to fish it ↗
Fly pattern · report suggests “PMD comparaduns”PMD ComparadunA pale slender body, split tail, upright semicircular deer-hair wing, and no hackle define the Comparadun profile.

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 “Stimulators”StimulatorLook for a hair tail, dubbed abdomen with palmered hackle, tented hair wing, contrasting front hackle, and bright thorax or head.

Treat the upper Madison as a lane-by-lane river. Pick one riffle, identify the soft edge, and fish each depth before moving.
02
A dry-dropper is a strong searching rig when flows are approachable. Use a buoyant attractor and adjust dropper depth often.
03
For nymphing, use enough weight to tick bottom occasionally, but avoid dragging heavy rigs through shallow riffle lanes.
04
During caddis or PMD activity, skate or swing a soft hackle below a dry fly before changing spots.
05
For streamer fishing, make short, accurate casts to banks, boulders, and color changes rather than blind-casting the whole river.

Common questions
Before you leave.
What flow source should I use for the Madison near West Yellowstone?+
Use the RiverReports page for the quick chart and USGS 06037500 as the official station reference.
Is the Madison good for dry flies?+
Yes, especially during caddis, PMD, salmonfly, terrestrial, and fall BWO windows. Dry-dropper fishing is often a practical search method when fish are not visibly rising.
Is the Madison easy to wade?+
Some edges and riffles are approachable, but the river is fast, cold, and slick. Avoid crossings in elevated flows and carry a wading staff.
Do regulations change by section?+
Yes. Check Montana FWP regulations, restrictions, and access-site rules before fishing because section-specific and temporary rules can apply.
