Montana’s spring fishing season officially begins as ice melts, with prime angling on major rivers and lakes.

As of March 7, 2026, Montana’s fishing season is shifting from winter to spring, with Canyon Ferry Lake now ice-free and boat ramps open, marking the official start of spring fishing. Anglers are reporting success on the Madison and Missouri Rivers using small nymphs and midges, while waters like Echo Lake, Flathead Lake, and Koocanusa Reservoir are showing early activity for smallmouth, lake trout, and rainbows. Ice remains on smaller lakes, requiring caution due to variable conditions. The 2026 hunting regulations have been released, and the Leadore Angus Ranch is holding its bull sale featuring high-elevation adapted yearlings.
