Largemouth bass are a warm-water side of Montana: prairie reservoirs, irrigation storage, and brushy shorelines a long drive from a Madison River fly box. FWP classifies many of these as black bass or warm-water programs with daily limits and sometimes tournament addenda. Pair with Montana fishing overview for 2026.
