Posted by Angela Montana on September 23, 2025The following report is by Yellow Dog Flyfishing:Flow Data: Gallatin River near Gallatin Gateway, MTThe warm weather continues here in Bozeman for the next week or so. This can be a fun method to find some particularly large fish. Fishing a large foamy terrestrial dry with a perdigon or midge pupa dropper remains a great way to catch fish on the Gallatin. Overall the surface action is likely going to be a bit slow until the fall beatis start hatching in numbers. Make the most of the good weather as summer starts to wind down.
