Gallatin River

Fishing Conditions

August 12, 2020

The Gallatin from Gateway to Big Sky is the place to be! Flows are down and the fishing has been solid. If you head this way you can get them on streamers, nymphs, and dries. Pick your poison! However its certainly dry dropper season on the Gallatin and this is a tough rig to beat this time of year. Chubbies, ants, and hoppers are great dries for this rig as they can hold up a fairly heavy nymph. For a dropper, fish are eating attractor mayflies, caddis, PMD's, stones and soft hackles. Nocturnal stones have been hatching throughout the river and spruce moths are hatching in the canyon in big numbers. Fishing a smaller chubby with a spruce moth dry has produced some fantastic dry fly action. If you're not getting fish on the dead drift try twitching and skating those dries! You may see quite an abundance of Green Algae right below Big Sky, if you do find yourself in this area, above Big Sky, or lower in the Canyon may be a better option for fishing. 

***Avoid fishing from Shed's Bridge down to the Gallatins confluence as water temps are beyond what is considered safe for trout. The FWP Region 3 press release reads: "A hoot-owl restriction prohibiting fishing from 2 p.m. to midnight each day will go into effect on Aug. 6 to rthe following waterbodies: -The lower Gallatin River from the Highway 84 bridge near Four Corners to the Missouri River." Best to avoid this stretch all together and focus on fishing higher up for some better cooler water temps.***
