Fly Fishing The Warm River Idaho
The little known, twenty-six mile long Warm River gets
much of its water from springs. It begins in the
Caribou-Targhee National Forest near the border of
Yellowstone National Park. One reason for the lack of
popularity with visiting anglers is the river is a tributary to
the famous Henry's Fork of the Snake River.

The uppermost section is near the same as most any
other small mountain stream in the area but at Warm
Springs, the river's volume of water increases greatly
and it becomes more of a spring creek than a freestone
stream. From the Springs to its confluence with the
Henry's Fork, it's a rather sizeable stream.

Since much of it runs through the National Forest, it
offers plenty of fly fishing opportunities, but some of it
comes at a price. Hiking is required to reach much of the
uppermost section and part of it runs through a very
difficult to access canyon. Some parts can be reached
from Forest Service roads.

Fly fishing the Warm River below the canyon below the
springs usually provides the best opportunities. The
river consist of pocket water with riffles and runs
connecting short pools. This area can be reached from
the Warm Springs Campground by following an old
railroad bed upstream to the lower end of the canyon..

You can access its upper section off of highway #47 via
Forest Service Road #367 North. The road runs along
the river. Forest Service road #150, off of 367, follows
the uppermost part of the headwaters. Below the
springs, Warm River Campground is located near the
much larger section of Warm River.

The high pH of the spring water provides a good habitat
for many aquatic insects and crustaceans that's very
similar to the nearby Henry's Fork. Matching the insects
that are most available and plentiful at any given time
will increase your odds of success. Our Perfect Flies
work great for the Warm River and, of course, the
Henry's Fork.

Seasons follow the general Idaho fishing season.
After the runoff, fishing is usually good.
Summertime is the best time for fly fishing the Warm
Fall, especially the early part of Fall, presents some
good opportunities.
