Fly Fishing Report – The Middle Fork Flathead
River Montana
Before we get started, please note that understanding how the Flathead River system is made up can be a little confusing for those that are not familiar with it. This is about the Middle Fork of the Flathead River. There are three other Flathead Rivers that are completely separate rivers. They are the North and South Forks of the Flathead River and the Main Stem which is just called the Flathead River. Each of these three other rivers are covered in a separate section of our Perfect Fly Stream section.

The Main Stem of the Flathead River is formed by the confluence of the North Fork of the Flathead River and the Middle Fork of the Flathead River. The South Fork of the Flathead River enters the Main Stem of the Flathead about five miles below Hungry Horse Dam. Fly fishing the Middle Fork Flathead River ranges from easy to very difficult, depending on the section you choose to fish.

The Middle Fork Flathead River is a 92 mile long river part of which forms the Southwestern boundary of Glacier National Park. Its drains an area east of the South Fork Flathead River. The Middle Fork Flathead River starts in the Bob Marshall Wilderness at the confluence of Strawberry Creek and Bowl Creek. It receives some small tributaries along its way including some from the Glacier National Park.

The Wilderness section of the river is very remote and it is a very fast flowing river known for its whitewater. To reach it requires a long hike or horseback ride. This section is about 25 miles long. Fly fishing the Middle Fork Flathead River in this section is more of an adventure than anything. The fishing opportunities are good but not spectacular. The water stays very cold from melting snow.

The wilderness section contains plenty of cutthroats up to 16 inches but again, requires a long hike or horseback trip. Outfitters are available for trips into this section of the river.

Access to the Middle Fork Flathead River near Essex is good. The river parallels U.S. Highway #2. The river flows for several miles through a twisting, narrow area but as it reaches an open valley at a lower elevations it begins to spread out and become braided in places. Downstream below the valley it again flows through a canyon like area. It finally meets the North Fork of the
Flathead River to form the main stem.

Middle Fork Flathead River Hatches and Trout
Flies:
The Middle Fork Flathead River is a cold river. Compared to other Montana trout streams nd even other Flathead River sections, it takes a good while to warm up and consequently, the hatches usually run later. Some anglers think the fly isn’t important because it is possible to catch the trout on various generic and attractor flies. We sell all of them at Perfect Fly but to not mislead you, it is important to understand you will always do much better if you imitate the most plentiful and available trout food at the place and time your fishing.

We have studied the insects in the Middle Fork and have taken samples of the larvae at various times. We have developed hatch charts we use to help customers select flies for their trips to the Flathead. It is important to know the species of insects vary from the freestone sections and tailwater. Streamers and midges are king in the tailwaters but there are other insects.

The two most important mayflies by far are the Blue-winded olives and Pale Morning Duns. Several different species are called BWO and they range from a hook size 20 to 16. Both the mayflies hatch over a long period of time. Others species include Green Drakes,
Small Western Green Drakes called Flavs, Pink Ladies or Yellow quills, Gray Drakes and others including the little Tricos (white winged curse) in some areas. Caddisflies consist mostly of various species of Spotted Sedges, Little Sister caddis and Green Sedges. There are a lot of the little Short-horned sedges, as well as October Caddis for a short time in the fall. There are other species of less importance. Stoneflies are very plentiful and include the huge Salmonflies. Golden Stoneflies and Little Yellow stoneflies. All three of these are very important insects to imitate, especially during a hatch. During the hot months you will find imitations of the Japanese Beetle, Black Carpenter ants and various sizes of Grasshoppers work well. Midges are everywhere year-round but most important in the tailwaters. Sculpin are by far the most plentiful species of fish the trout eat.

Fly Fishing Gear, Tackle and Trout Flies for The North Fork Of The Flathead River Montana

Fly Line:
We recommend fly lines ranging from a 5 weight for dry flies to a six weight for nymphs and streamers.

Leaders:
You should have leaders ranging from a 9 foot tapered leader to a 12 foot in sizes from 0X
for streamers up to a 7X for midges and tiny flies. You may want some shorter streamer
leaders.

Tippet:
Carry tippet ranging in sizes from 0x to 7X.

Fly Rod:
The fly rod for the 5 weight line should be nine feet long to assist in casting in the wind
normal for the North Fork Flathead River, in a medium fast action. The six weight should
be nine feet long in a medium fast action with a stiffer tip for nymphing.

Fly Reel:
Reels for the lines sizes you choose to use in the 5 and 6 weight line size should be light
and have good drags.

Waders:
Waders are definitely recommended. We prefer the breathable type but neoprene may be
better in cold weather.

Wading Boots:
Felt soled wading boots are our choice.

Landing Net:
A landing net is recommended, but not a requirement.

Trout Flies:
Our “Perfect Flies” are the best ones you could possibly use for fly fishing the North Fork
Flathead River. We have flies to match every terrestrial and aquatic insect in all stages of
life. If you haven’t done so already, please give them a try. You will be glad you did. Having
good imitations of the insects the trout see day in and day out is a big advantage.
