Gallatin River Fishing Report

Date: 07/12/2024
Posted by: Toby Swank

Gallatin River fishing has been steadily improving over the last 10 days as the river is clearing and dropping quickly now that the runoff has slowed.

Dry fly fishing in the Gallatin Canyon and upper sections has been very fun the last week as there is an abundance of insects around right now. The Salmonflies are pretty much gone, but fish will still come up and eat a large imitation with some gold or orange on the underneath side. These work great to suspend the heavy dropper nymphs that have been productive in the deeper runs and pocket water.

Anglers fishing throughout the river’s course have been finding success fishing a single dry as well. Yellow Sally, Caddis, and a variety of mid-sized (10-14) attractor dry fly patterns have all been productive at time.

The lower river is still relatively high, making streamer fly fishing the most consistent method for anglers floating and fly fishing below Manhattan.

Montana fly fishing trips on the Gallatin River with the team at Fins and Feathers Guide Service focus on the lower stretches. Floating the lower Gallatin River offers access to blue-ribbon trout waters that receive much less angling pressure than the upper river. Hazardous obstructions in the river are constantly shifting, making floating here more challenging than other rivers near Bozeman.

Trophy Rainbow and Brown Trout are here for the experienced angler willing to streamer fly fish during early summer days. Novice anglers quickly improve their skills as our guides patiently coach them through the intricacies of reading water and fishing near structures on this wild stretch of river.

The river is known for its clean, cold water and offers over 75 miles of blue-ribbon trout water accessible at turnouts along HWY 191 and throughout the Gallatin Valley.
