Today's Fishing Report

Generated this morning from live readings: gauge, weather model, sun and moon. A fresh report is published here every morning.

2/5Slow. The wind owns today.25 mph gusts make boat control the real battle.

Madison River is in its winter mode: slow, deep and deliberate. The river is running 1,310 cfs, steady over the week. Today brings cloud cover, wind S around 13 mph, rising pressure near 1008 hPa and a high of 53. Water sits around 47 F for the season (estimated). With the waxing gibbous, the solunar majors run 10:04 AM-12:04 PM and 10:35 PM-12:35 AM: the windows to build the day around.

The plan, species by species

Rainbow troutExcellent

In cold water rainbows use the deepest pools in rivers (Vermont), so slow, deep drifts there are the usual approach; Michigan DNR notes lake rainbows are also taken with bait or by jigging through the ice.

Brown troutExcellent

Below 50Β°F, fish slowly through the deeper pools; in early spring on the Great Lakes, Michigan DNR notes browns are often caught inshore before other species start biting.

Tomorrow: Similar at 49 F. The solunar majors shift about 50 minutes later.Next report: Sat, Oct 24, 6:30 AMHow this report is made β†’

Rainbow trout illustration

Rainbow trout

Spring and fall in most lakes; rivers fish year-round while the water stays cool

A cold-water trout native to Pacific drainages from Alaska to Baja California, now stocked in most states and fished in rivers, tailwaters and lakes. In cold water rainbows use the deepest pools in rivers (Vermont), so slow, deep drifts there are the usual approach; Michigan DNR notes lake rainbows are also taken with bait or by jigging through the ice.

Brown trout illustration

Brown trout

Spring along Great Lakes shorelines; low light and overcast days in rivers; fall spawning runs

A European trout first stocked in the US in 1883 and now fished in rivers and lakes nationwide; it tolerates warmer water than other trout, and mature stream fish feed mostly at night. Below 50Β°F, fish slowly through the deeper pools; in early spring on the Great Lakes, Michigan DNR notes browns are often caught inshore before other species start biting.

Before you go

License

Montana requires a valid fishing license for adults. Buy online from the state agency; one-day options exist for visitors.

Regulations

Montana license + AIS pass. Upper river largely artificial lures/flies only, catch-and-release varies by reach; check the current FWP regulations for the Madison drainage.

Access

Legendary public access: $3 Bridge, Raynolds, Lyons Bridge, McAtee, Varney and Ennis FAS sites ladder the whole river. Fly shops in Ennis and West Yellowstone post daily flows and hatches.

About this water

Blue-ribbon trout river, ~140 miles from Yellowstone Park to Three Forks, MT. The Quake-to-Ennis reach is the famed Fifty-Mile Riffle. Managed by Montana FWP.

Fishing Madison River: the full guide

One long riffle

From Quake Lake to Ennis, the Madison runs as a single broken riffle for fifty miles: pocket water end to end, browns and rainbows averaging a legitimate 14-16 inches, and hatches that set the calendar for the whole fly-fishing world (salmonfly in late June, hoppers by August). It is Montana's most pressured river and somehow still its most generous.

The upper, the fifty, the lower

Between the lakes (Hebgen to Quake) is a short, big-fish tailwater section. The famous Fifty-Mile Riffle (Quake to Ennis) fishes the same everywhere and differently every day: nymph the seams, throw attractor dries against the banks from a drifting boat, streamers when clouds roll. Below Ennis Lake, the Bear Trap Canyon wilderness section holds big browns for those who hike, and the lower river toward Three Forks becomes a warm, moody big-fish game best in spring and fall.

Rules and rhythms

Much of the upper river is artificials-only, and regulations change by reach: read the current FWP book. Summer weekends bring flotillas: fish early, fish late, or walk the wade-only water between the lakes. Winter midge fishing on the upper river is underrated for those in the know.

Common questions

When is the salmonfly hatch on the Madison?

Typically the last week of June into early July, moving upstream day by day: three-inch bugs, reckless fish and full campgrounds. Hit it right and it is the show of the season.

Can beginners fish the Madison?

It is one of the best learning rivers anywhere: forgiving pocket water where a high-floating attractor dry and a rough drift still catch fish. Hire an Ennis guide for a day and shortcut a season of lessons.

How does the wind factor in?

It howls up the valley most afternoons: plan casting angles with it, not against it, and get the good fishing done by early afternoon in summer.

The written guide on this page
Pablo Ruiz Quintero
How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written guide was drafted with AI assistance. Unlike our newer pages, it does not yet list the official pages its facts were checked against: that audit is under way, and anything it cannot verify will be taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Errors are published in the verification log; the full policy is in the editorial policy.

Readings refresh on a 30-minute window. The full method, with every figure and its source, is on how our reports are made. Something wrong here? Tell us and it goes in the log with the date.
