Upper Madison River Fishing Report

Date: 09/25/2026
Posted by: Toby Swank

Current Conditions

The Upper Madison River has been challenging overall. There’s been more bug activity showing up in the afternoons, but that hasn’t translated into a lot of fish willing to move for dries. Low, clear water isn’t helping, and dropping down to 4X fluorocarbon has been making a difference.

Nymphing remains the most effective way to fish it. A pat’s rubberlegs with a size 18 black infernogon or another small attractor nymph has been a solid setup. Keep the rig light enough to fish cleanly through the shallower water.

Closer to Ennis, streamers have been getting the attention of a few better fish. Black and olive are worth throwing, but expect to cover some water between opportunities.
