Lower Madison River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Lower Madison River is fishing well for this time of year, especially once the day warms up. Cold mornings keep things quiet, but by late morning the river has been producing steady action in the slower, deeper water.
Nymphing is the main approach right now. Zirdles, small crayfish patterns, worms, zebra midges, and slim perdigons have all been working when fished close to the bottom. A 9-foot fluorocarbon leader of 4X with 4X to the dropper keeps the setup straightforward and effective. Adjusting weight to reach the right depth is more important than switching patterns.
Most trout are sitting in softer current with enough depth to hold consistent temperatures. Faster water isn’t offering much this time of year.
Streamer fishing is still possible on warmer afternoons. Smaller sculpin or leech-style flies can pick up a few fish, though it’s not something to rely on every day. A short leader of heavier fluorocarbon helps turn those patterns over.
Dry-fly opportunities are minimal, but a few midges may show later in the afternoon. Rising fish have been rare.
The Lower Madison remains one of the more dependable winter options near Bozeman thanks to its consistent flows and easy access. Aim for a later start, focus on deeper holding water, and stick with nymphs for the most consistent results.
