Fly Fishing The Kootenai River Montana
The Kootenai River is the Kootenay River in Canada. It
is historically called the Flatbow River. It's a major river
in southeastern British Columbia and northwestern
Montana. It's a major tributary of the Columbia River.
The Kootenai River runs for about 485 miles from its
origin in the Kootenay Ranges of the Canadian Rockies.
It enters northwestern Montana and the northernmost
part of the Idaho Panhandle and returns into Canada.
It's a glacier stream that flows through a rugged
landscape of mountains and valleys.
Fly fishing the Kootenai River is a real experience. It's a
big, fast river that can be dangerous to fish from a drift
boat at times. Drifting the river is a boat is the best way
to fish it. It can only be waded when the water is low.
There's yet another problem. A prime section of the
Kootenai River is a tailwater and you have to watch the
flow, especially if you wade it. Water from Libby Dam can
change the flow in a heart beat. The Kootenai River
holds the state of Montana's rainbow trout record as well
as its whitefish record. Both fish were caught below
Fly fishing the Kootenai River can be difficult. It is
usually running high and fast during the Summer. The
tailwater section of the Kootenai River is seventeen
miles long. The tailwater is wide and usually has fast
flowing water. There are some braided areas along with
runs and deep pools. Access to the tailwater section is
great. There are several boat ramps. Highway #37
follows along the Kootenai River much of its length
From Libby to the Idaho state line, the Kootenai River
runs for about thirty miles. The best fishing in this area
is above Kootenai Falls. This section of the Kootenai
River has more riffles and pocket water than the section
below the dam. Access is difficult on this section of the
Kootenai River. It flows through private property. The
Kootenai Falls area has some good access points. The
Yaak River, a tributary stream, joins in on the flow at
Libby. Fishing below Kootenai Falls is also possible but
it's not quite as good as the above two sections.
The Kootenai has lots of different aquatic insects and
they vary from the freestone sections to the tailwater.
The most plentiful mayflies are the Blue-winged olives
and Pale Morning duns but there are many more. The
tailwaters have tricos. Caddisflies consist mostly of
Spotted Sedges, Little Shorthorned sedges and October
Caddis but again, there are others.
Sculpin are plentiful throughout the river in both sections
and so are midges. Midges are very important in the
Fly fishing the Kootenai River can be good any day of
Springtime is a good time for fly fishing the Kootenai
River. The tailwater section is usually clear even during
Summertime is the most popular time to fish the river.
Fall is a good time to fish the tailwater section of the
