Fly Fishing Big Wood River Idaho
The Big Wood River's name comes from the many
cottonwood trees that line the banks of the river. It is a
nice freestone stream that has a good population of
rainbow trout. The stream has several access point most
of which are off of Utah Highway #75 which follows the
river for most of its length.

The river headwaters start near Galena Summit in the
Sawtooth Mountain Range. It flows between the Pioneer
Mountains and the Boulder Mountains and Smoky
Mountains before entering beautiful Sun Valley. Its North
Fork enters the main river about ten miles north of
Ketchum. Its East Fork, flowing from the Pioneer
Mountains, joins in on the flow below Ketchum at Gimlet.
From Sun Valley the river flows into Wood River Valley
and finally into Magic Reservoir.

Fly Fishing Big Wood River is affected by two things -
the snow pack and irrigation needs. Irrigation for
agricultural needs can drain the lower end of the stream
of much of its water affecting the water temperatures
and fishing. On wet years Where there is lots of rain and
a deep snow pack, fishing remains good for the entire
year. When there is a deep winter snow pack, the runoff
can last until near the end of June.
                     
Seasons:
Some areas are open year-round for catch and release.
You have to check current regulations.
Winter:
It is possible to fish the stream during the winter but the
fishing is usually tough.
Spring:
Except for the runoff time, springtime is great because of
the hatches.
Summer:
After the runoff ends, anywhere from mid to late June,
the fishing is usually very good.
Fall:
Fall may be the very best time for fly fishing Big Wood
River.

Fly Fishing Guide to the Big Wood River:
Most of the trout above Ketchum are rainbows. There
are some browns on the lower end of the stream but
they usually only average around ten to twelve inches.
