Montana and Missouri River fishing reports for October 2026

Anglers in the Missouri River and Montana regions are preparing for seasonal shifts in fishing conditions during October 2026. In the Missouri River area, recent weather has remained warmer than typical autumn patterns, with temperatures staying above 70°F. This sunlight has influenced fish behavior, leading many to suggest nymph fishing while trout remain hidden from the sun.

In Montana, fishing reports indicate changing water conditions and various local updates for anglers. Regional reports cover diverse locations, including the Stillwater River, Helena area reservoirs, and Fort Peck, as outdoor enthusiasts navigate the transition into the fall season.
