April 16, 2023 Gallatin River Fishing Report
Date: 04/16/2023
Posted by: Toby SwankCurrent Conditions
Yo Yo flows the last week has been moving some ice and debris around, so be careful walking around while fly-fishing out there - especially near Bozeman in the Gallatin Valley. Fishing has been improving the last few days as flows dropped back down with the return of some cold weather. Nymphing with Stonefly Nymphs, San Juan Worms, Prince Nymphs, and egg patterns is the best bet. There is the odd Skwala around, so a Chubby Chernobyl in olive or purple with a heavy dropper is worth a few casts around good water as well. Expect BWO and Midge dry fly fishing to be slow until we see more consistent weather conditions, but rising fish can be found sporadically in the canyon sections in the afternoons along slow seams.

Gallatin River Fishing
The Gallatin River starts small in YNP and becomes a medium-sized western river below Big Sky, Montana. It flows through Gallatin Canyon with swift pockets and fast runs. 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. The Gallatin River joins the Jefferson and Madison Rivers to form the Missouri River near Three Forks, Montana.
