Lower Madison River Fishing Report

Date: 05/01/2026
Posted by: Toby Swank

Current Conditions

The Lower Madison River is in a good place right now and starting to feel like it’s on the edge of that next shift. Bug activity has picked up, and it’s lining up with what you’d expect this time of year.

Fish are still holding in the buckets and deeper runs, but there’s more movement toward softer edges as bugs start to come off. You can find fish feeding in a few different types of water now, especially during the warmer parts of the day.

Nymphing is still the most consistent approach. Smaller baetis nymphs, pheasant tails, and perdigon-style flies paired under a heavier crayfish attractor have been producing. Keep everything down and don’t rush your drifts. If you’re not occasionally ticking bottom, add weight before changing flies.

There are BWOs, march browns, and some caddis showing. It’s not full-on yet, but there are windows where fish are looking up, especially in the afternoons. You might not build a full day around dries yet, but it’s worth being ready.

Streamer fishing has been mixed and not something to focus on with bugs starting to show.

The Lower is close. With caddis already coming off in good numbers on nearby rivers, it feels like it’s just about to turn on here as well. Keep an eye on the afternoons and be ready to switch when it happens.
