Fly Fishing North Fork Flathead River
Before we get started, understanding the Flathead River
and its three forks can be a little confusing for those that
are not familiar with it. There are three other Flathead
Rivers that are completely separate rivers even though
they are connected together. They are the
Middle 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. Make sure you are
reading about the one you plan to fish.

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 that
forms the big Hungry Horse Reservoir on the South
Fork. This river's drainage is huge, including a large
part of Glacier National Park and the Bob Marshall
Wilderness Complex.

The North Fork Flathead River flows from British
Columbia, Canada, for a length of about 45 miles south
into the Montana where it helps form the Main Stem of
the Flathead River. It's overall length is 153 miles. Its
section that lies in the U. S. is a designated National
Wild and Scenic River. It forms the western boundary of
Glacier National Park. It is a true wilderness river. It's
also a very wide and cold river, fed mostly by melting
snow. Fly fishing the North Fork Flathead River is a real
adventure. It winds through beautiful mountains with
great views of the Glacier National Park.

The river has rainbow and cutthroat trout, the majority of
which are smaller sizes, but they are plentiful and fairly
easy to catch. The river also host some big Bull Trout
but they should be released unharmed. The river has
little to no pressure from anglers. Access is easy and
plentiful. The North Fork Road follows fairly close to the
river for a majority of its length in the Montana.

Fly fishing the North Fork Flathead River is best done
from a drift boat. There are plenty of access points
along the way and unless the water is very high, the
river usually provides a relatively easy float through
some of the most gorgeous scenery you will find
anywhere. It can also be fished by wading in many
places. It is just that you can cover a lot more water by
drifting the river.

Seasons follow the general Montana fishing season.
Late springtime has some fishing opportunities except
during runoff.
The Summer would be best time for fly fishing the North
Fork Flathead.
Early Fall can be good.

is the end of the runoff, or the effects of the colder weather.

two caddis species and little Yellow stones hatching. Some Goldens are still in the higher
