The western mountains of Montana offer some remarkable fly fishing. In these lakes and streams trout fishing is more of a religion than a sport. Montana is known for the best kind of fly fishing there is, fishing with dry flies.
The head waters of the Missouri river, near three forks, are an example of some astonishing fly fishing waters. Here the Gallatin River and Madison River and the Jefferson River all merge together to form the Missouri river. All four of these separate rivers are incredible fly fishing rivers, but the area where they all merge is just mind blowing. There are small islands and sand bars. There is a bridge that goes across the area that offers protection and shade for fish to bide their time. These rivers offer wonderful trout fishing for browns, rainbows, and cutthroats. There it is possible to catch a 20 inch fish on #20 fish hooks.
The Yellowstone River, coming out of Yellowstone National Park, all the way up to Livingstone, has some marvelous fly fishing. This piece of water fishes well with dry flies in the summer right before sunset. Streamers work well on the hot summer days. There are many hatches that come off of this water during this time of year. It is also pretty along the river.
In the northwest corner of the state the Kootenay River dips down from Canada and brings some remarkable fly fishing. The tail waters below the Libby dam and downstream from Jennings has great nymphing. Using a drift boat or just wading through this water is pretty and the fishing so great that you’ll never want to leave. On down the river below Kooteenai Falls the river calms down and becomes a great fly fishing destination.
