From the benchWith flows at 544 CFS the Gallatin has some push to it — focus your nymphing in the seams just off the main current where fish can hold without burning energy. Set your indicator depth to at least 1.5x the water depth in the runs and use a heavier anchor fly like the Frenchie Jig to get down fast in the canyon slots. When the fog burns off around 10 AM and the sun hits the water, switch your attention to the slower tailouts and watch for rising fish — the BWO and midge activity during that transition window can produce some of the best dry fly fishing of the day. As afternoon temps climb toward 68°F, walk the grassy valley banks and prospect with a terrestrial pattern before the streamer bite kicks in during the last hour of light.
