Gallatin River Fishing Report

 (1)
Maclean’s famous story, A River Runs Through It, is set on the now famous Blackfoot River. Despite this, Robert Redford’s 1992 movie version was largely filmed on the Gallatin as he felt the scenery and fishing were more cinematic. The river originates high in the mountains of the Gallatin Range inside Yellowstone National Park and flows for 115 miles until it intersects with the beginning of the Missouri River at Three Forks. Inside the Park, where it runs for more than 25 miles, floating is not allowed and there are restrictions on fishing. Once it exits the park, it crosses a forty-mile expanse of mostly public lands, and runs parallel to a highway that makes it quite accessible. Because the river is narrow for much of its run, float fishing is restricted from Yellowstone Park to the confluence with the East Gallatin River. No wonder this river has a great reputation for wade fishing!

Unimpeded by dams, the river provides consistent, easily waded flows from mid-summer through mid-spring. Rainbows predominate with an estimated 1400, 8+ inch, fish per mile from the West Fork confluence at Big Sky to the mouth of the canyon. Browns are abundant accompanied by occasional cutthroats, brook trout, white fish and graylings. New to the lower most band of the river are northern pike. Never known for trophy trout, the river offers excellent dry fly fishing and beautiful surroundings. Since the fish are recognized as indiscriminate eaters, the Gallatin has come to be known as an excellent river for those learning to fly fish.

Like much of Montana, the River played a significant role in the state’s history. First explored by Native American hunters, by the early 1900’s, the area eventually became known to fur-trappers and gold prospectors. By the turn of the twentieth century logging rose in importance to the local economy as loggers famously rode the logs down river to prevent them from jamming. The towns of Bozeman and Three Forks are most closely associated with the River although given the importance of Maclean’s legacy, Livingston should also be considered as part of its history and heritage.

This has been providing some good fishing. The open canyon and valley stretches of waters up to Big Sky are fishing very well. The winter stones are hatching so nymphing seems to be the best. Small black stonefly nymphs are working the best. It is best to jump from one deep run to another. Look for currents that are steady enough to bring food to trout yet not too strong.
