Bozeman Fly Fishing Guide to September

Bozeman Fly Fishing in September

Autumn arrives in Bozeman by the end of September bringing changing leaves lining the rivers and cool, crisp air to the valley. Hear bugling elk in the mornings along the blue-ribbon Montana fly fishing rivers near town. Summer crowds thin considerably, leaving the rivers to the anglers fishing for the increasingly active trout.

The Bozeman community comes alive as students return to Montana State University, making for some great nightlife downtown. September is a great time of the year to plan a Montana fly-fishing trip to Bozeman.

Our home rivers cool dramatically, triggering the aggressive tendencies of brown trout, so September and October are prime months to target trophy Brown Trout. Yellowstone River fishing is almost entirely subsurface as anglers search for big fish on the move. The Jefferson and lower Madison Rivers fish well once again as irrigation demands decrease and water temperatures drop. Floating the Gallatin River provides reliable action and respite from other anglers fishing in the region.

September Highlights

  • Late-season terrestrial fishing persists on the Jefferson and lower Yellowstone Rivers once water temperatures drop in early September.
  • Gallatin River fishing in the canyon stretches offers technical fishing for the advanced angler during fall BWO hatches on cloudy days. Long leaders, fine tippets, and stealthy approaches are keys to success.
  • Casting streamers for big brown trout is the focus for many anglers fishing the Montana rivers throughout fall. This is the best time of the year to target these fish on the Yellowstone and Madison Rivers.

Bozeman Fly Fishing Guide Pro Tip:

Try the waters of the Missouri River, below Toston Dam to find solitude and a few chances at some truly large brown trout. There aren’t many trout in the river here, but there are some big ones that become increasingly active with cooler weather. Keep your expectations low and swing big!
