Hatch-chart pattern list

Best Flies for Madison River (Montana)

The Madison is a two-river problem. Above Ennis Lake you are fishing a broad riffle-and-run meadow for rainbows and browns that see a lot of rubber legs. Below the lake the water warms, the wade game opens up, and caddis and PMDs do more of the work than the salmonfly posters suggest. This list is built from the hatch chart we publish for the river, not from anyone else's catch log.

This is not a live report of other anglers' catches. Presence and flow live on the Madison River river page and the Montana destination guide.

What's hatching now

Nymphs

Subsurface patterns matched to this river's chart and catalog. Fish them at the size the chart lists, not the size that looks good in the bin.

Dries

Dries and terrestrials for the Madison River. If the chart says a size 18 PMD, do not start with a 12.

Streamers

Streamers and wets for stained water, banks, and low light. This is not a claim that streamers are "on" today.

Setup

4X and 5X cover most nymphing. 4X on dries until the fish get picky, then 5X. A 3.0–3.8mm tungsten on the point and a lighter dropper is a default until you see the water. Tight-line the near bank and the heads of pockets. Use an indicator only when you need to search water you cannot euro.

FAQ

What flies work on the Madison River?
Start with March Brown Wet and BWO Sparkle Dun, then match size to the hatch chart for the month you are standing in. The Madison River does not need a 40-pattern box. It needs the right size on the insect that is actually in the drift.
When is the best time to fly fish the Madison River?
The editorial window we list is June, July, August, September, October. That is a planning month range, not a guarantee. Shoulder months can fish well if flows and water temperature cooperate.
Do I need a guide on the Madison River?
Montana has walk-up wade water and, on some sections, float water. A guide is worth it for a first float or a technical tailwater. A hatch chart and a gauge are enough for a first wade if you already nymph. We list local guides and shops on this page when we have them.
Where can I see live flow for the Madison River?
Open the Madison River river page for the USGS gauge, access notes, and the same hatch chart this fly list is built from. We do not publish other people's spots or fish counts.
Is this a report of what's working now on the Madison River?
No. Executive Angler does not publish other anglers' catches, GPS, or a crowdsourced hot fly. This page is hatch-chart patterns plus catalog flies. Presence on the river page is gauge and weather only.
