Catching trout on the Madison River

May 5, 2026

Thank you for checking out our most recent upper Madison River fishing report. It is our goal to keep this page updated on a regular basis to serve as a resource for those of you planning your visit to Montana. Please refer to the information below consisting of fishing techniques, fly patterns, Madison River flows and the weather in Ennis, Montana. We encourage you to give us a call for more information not detailed in our fishing report.

Overview

Beautiful spring conditions and some excellent fishing to be had!

Ennis, Montana Weather

Warm spring air temperatures and plenty of sunshine as of late. A northerly flow kicked in over night, cooling things down. We are expecting things to cool down tomorrow before returning to epic spring conditions.

Madison River Flows

The river is very low at the moment as they fill up Hebgen Lake. Skilled rowing and one eye peeled for sneaky rocks helps. Still plenty floatable as always! Consider a raft if you have one at your disposal.

Madison River Hatches

BWOs and March browns have slowed a little bit with this sunny weather. There has been a great caddis hatch in the afternoon.

Fishing Techniques

Dry flies such as a #18-14 Parachute Adams have worked well in the slicks for mayfly sipping trout. Caddis have been working in the riffles and big runs. The fish are taking streamers well at times, particular olive and white patterns. Nymphing is good as usual using a medium Girdle Bug followed by a wide variety of nymphs, worms and eggs.

Madison River Flies (Year-Round)

To simplify things, you can expect Madison River trout to eat just about every classic trout pattern ever tied depending on the time of year. Known for prolific stonefly, caddis, mayfly and midge hatches, the trout of the Madison aren't as picky as other rivers. If you get the size and color right, chances are they'll eat it so long as you have the correct presentation. Certainly there are some local secrets, but if you stock up on the basics you should be just fine!

Madison River Fishing Gear

A 5 or 6 WT fly rod is ideal for most fly fishing situations on the Madison River. The Madison Valley can be a breezy place and with such a wide river it can help to have a little extra power in your cast. We tend to prefer fast action fly rods for this reason. Your fly line is arguably more important than your fly rod though. Half size heavy weight forward floating lines are the ideal compliment to a modern fast action rod.

A slow action 3-5 WT certainly has its time and place on this river, especially during the caddis, midge and BWO hatches. 7 WT rods are commonly fished with short sink-tip fly lines and big streamers. They also come in handy during the salmonfly hatch when you're casting a 3" long foam body dry fly.

Breathable waders and sturdy boots are often a necessity during the spring and fall months. Your best soles for traction are felt with carbide tipped studs. Be aware that many Madison River fly fishing guides do not allow studs in their boats. It is rare that waders are required between June 15-September 15. During these months, some lightweight boots or water shoes/sandals are preferred.

Above all else, quality clothing and accessories for all types of weather are essential for staying comfortable during the day. Montana can throw just about any type of weather your way so be prepared with a well thought out layering system to handle the often cold mornings and warm afternoons.
