Fly Fishing Report South Fork Flathead River Montana
Of the three forks of the Flathead River, as well as the main stem of the river, the South Fork offers the best fishing opportunities. The reason is very simple. Few anglers will go to the trouble to reach it to fish it and the fishing regulations help protect it even more. Fly fishing the South Fork of the Flathead River should remain a favorite for the explorer type of angler for a long time. It has plenty of good size cutthroat and rainbow trout along with some grayling and some fully protected bull trout. The South Fork is the favorite of the Flatheads.

The South Fork of the Flathead River is a truly remote stream. It forms in the Bob Marshall Wilderness, one of if not the largest wilderness area in the states. It can only be accessed by foot or horseback.  We don’t often do this, but in this case, if your going to fish the upper section of the river, we recommend you use an outfitter.

Access is to the wilderness is very good. There are many trials that transverse the giant area of the Bob Marshall Wilderness. The South Fork of the Flathead River can be accessed from the upper end of the Hungry Horse Reservoir which you can be reached by traveling about fifty miles on a dirt road. From there you have to either travel by horseback or backpack in. A trialhead leads to the South Fork of the river. The South Fork Trail follows the river for its entire length.

The South Fork of the Flathead River is over forty miles long before also five miles of the stream in the tailwater section between the dam and the main stem of the Flathead River.

Even when you arrive, you will find the South Fork of the Flathead River very difficult to fish. It flows for several miles through the Meadow Creek Gorge, a deep canyon-like area. You must hike in a good ways from the trialhead to fish. Once you get to the river, unless the water is very high, you will find it easy to wade.

There are several special fishing regulations that apply to the wilderness portion of the South Fork of the Flathead River. You should make certain you check the current regulations prior to fishing the river.

The South Fork tailwater below Hungry Horse Dam flows for only five miles before it joins the main stem of the Flathead River, but It too, provides some good fly fishing opportunities. Except for a few locals, most anglers that travel that far to fish, do so to fish the wilderness area.

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.
