Gallatin River Fishing Reports
Updated Apr 22, 24

Flow Data: Gallatin River near Gallatin Gateway, MT

The Gallatin gained a good bit of water with the last warm weather and is now a bit off color. The cool weather this week should help the river clear up quickly. Once it is clear again the Gallatin will fish well. Midges have been hatching in good numbers as have BWO's in the valley. Skwalas have been spotted here and there as well. Fishing an olive or peacock bodied chubby with an olive Perdigon dropper can be very effective as we get into this spring like weather. Nymphing has been really good with a stonefly nymph and a small attractor or olive mayfly nymph under an indicator. Our favorite nymphs include black/brown Pat's Rubberleg trailed by a #16 or #14 Purple Lite Brite Perdigon. A wine San Juan Worm or a twisted Stone will also be great options. If you feel the need to strip streamers, something that is small and heavy slowly moved along the bottom of deep holes will be the best option. A smoke Sparkle minnow or olive Wooly Bugger provide an angler with winter success.
