August 12, 2023 Gallatin River Fishing Report
Date: 08/12/2023
Posted by: Toby SwankCurrent Conditions
Thundershowers in the headwaters of the Gallatin and the Taylor's Fork have caused the river to have variable clarity the last week. It has been fishing pretty well - when there is decent visibility - with dry/dropper rigs during the early morning hours in and above the Gallatin Canyon. Nymphing the deeper pools in the Gallatin Valley and canyon has been ok with generalist patterns like Psycho Princes and Copper Johns followed by small lightning bugs or purple Perdition-style nymphs under an indicator. Spruce Moths are out and about with more showing up all of the time right now so doing some prospecting with a large Elk Hair Caddis is starting to work more and more, as well.

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.
