Planning Your Fly-fishing Trip To Yellowstone
|........................... ......................Fly Fishing Yellowstone National Park
When to Come and What To Expect:
Fly Fishing: Outside Yellowstone National Park - Gallatin River
The Gallatin River begins in Yellowstone National Park and flows out of it near highway
#191 across the parks north border. It flows all the way to Three Forks were it helps
form the Missouri River. About ninety miles of the river is outside of Yellowstone
National Park. During that course, it has a wide variety of water types.
After leaving the park, it flows through steep mountains, especially below Big Sky. Parts
of the rough, white water sections of the stream provides great fishing in August. After
it gets through about forty miles of mountains, it slows down and flows for its next fifty
miles through a large valley. The river widens out and drift boat fishing becomes
The fast water sections are difficult to fish in places but where you can fish you will
usually enjoy very good results. Use a heavy tippet of about 3X and grasshopper
imitations during August in this section. Be careful in the fast water sections of the
river. It is very rough pocket water that can hurt you if you are not careful.
A few miles below Gallatin Gateway, the river slows down and changes to long pools
and deep runs. There are some sections of fast water, but mostly slower, deeper
water. There are not nearly as many trout, but they are much larger. Look for the
shallow riffles near the ends of the pools.
The Gallatin River remains cold all month long, so you don't have to worry about the
water getting too warm. There are many places you can wade and catch trout or you
can choose to fish the lower section from a drift boat. We suggest fishing the faster
water by wading for the best results but you will need to select your places carefully.
Most of the time the parking pull offs will lead you to good fishing. If you will hike a short
ways from these areas, you can fish many places that rarely see a fly.
Don't overlook the Gallatin River, outside Yellowstone Park, for some good August fly
