Gallatin River Fishing Report

Friday, July 23, 2021
Gallatin River Montana

Current Conditions:

***A full fishing closure for portions of the Gallatin River from the mouth to Hwy 84 Crossing***

The higher sections of the Gallatin have cool waters and are fishing well. Once the river exits the canyon it warms fast and water levels drop due to irrigation pulls. Due to low water the river below Four Corners (downstream of Hwy 84) is closed to protect fish during warm summer weather and low flows. In the canyon and the upper river in Yellowstone Park the hatches are mostly over and fish are now focusing on terrestrials such as hoppers in meadows and spruce moths in forests.

The Month Ahead:

The Gallatin will offer good fishing in the mornings and early afternoons. Focus on the upper reaches above irrigation draws from the mouth of the canyon to through Big Sky and into YNP.

Long Term Fishing Forecast:

The Gallatin will be lower than normal this summer so pay attention to water temps and plan your fishing for early mornings. Water temps will begin dropping in late August when nights grow longer.
