Gallatin River Fishing Reports
Updated Apr 13, 24

Flow Data: Gallatin River near Gallatin Gateway, MT

The Gallatin is fishing great. High temperatures reach nearly 70 degrees by Friday. This temperature increase should be great for the aquatic insect activity. 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.

If you are planning to fish in the headwaters of the Gallatin River area above Taylor's Fork (approx. 1 mile upstream); be aware that most of this is in Yellowstone National Park which requires a separate fishing license and is seasonally open to fishing according to YNP regulations.

Fishing from a boat is not allowed on the Gallatin River from the headwaters downstream to the confluence of the West (main-stem) and East Gallatin River, however it is permissible to use a boat/craft for access for wade-fishing in this stretch of the river. Fishing from a boat is allowed downstream of this point to the rivers mouth.
