Spring fishing in Montana is prime between mid-March and late April, featuring slow trout behavior and a focus on nymphing. Anglers should utilize specific streamers and dry flies during warmer afternoons.

Low, steady flows out of Libby Dam (4,000 cfs) and mild weather have the Kootenai River fishing very doable heading into early March. With water temps around 40°F, expect limited dry-fly action—but consistent nymphing and slow, deep streamer presentations can still turn up quality fish, especially in softer 5+ foot holding water.

The Kootenai River is currently fishable with flows at 4,000 cfs and water temperatures around 45 degrees. Focus on subsurface presentations and streamers for better trout catches this week.

Winter conditions on the Kootenai River are optimal for fishing, with steady low flows and clear waters. Nymphing is the most effective technique, focusing on deep, slow-moving areas for trout.
