Action with unbelievable scenery.
What a beautiful place to fish.
Fly Fishing The Lamar River:
..............................................Fly Fishing Yellowstone National Park
Looking across the stream at the
bison with one standing  behind  
too close for comfort. The fishing
was so good, he stuck it out
valley. Some call them Prong Horns.
It 's rare you get this close to them.
They spook easily.
Large native cutthroats are the
stars of the Lamar River. Angie
took over 20 cutthroats all about
the same size as this one in one
July day.
The Lamar River  on your right
and the Soda Butte Creek on your
left flow together. Note how
muddy the Lamar is.
When you see this sign, you
know you have come to a great
place in many respects.
The Lamar River is located in the Northeastern portion of Yellowstone National
Park. It is located in a beautiful valley that is almost beyond description and

Upper Lamar River:
The river starts in the Absaroka Mountains and flows for over 30 miles before it
comes near a road. This means this part of the stream is rarely fished. But that is
not all bad because the trout in this part of the stream are smaller than those in
the lower, more accessible portion of the stream. As with many freestone
streams, the farther you travel upstream, the smaller you will find the fish.

The uppermost part of the Lamar River flows through a canyon and is very steep.  
The upper portion must be reached by hiking in or by horseback trips. Campsites
are available along the stream. The total length of the stream is over 43 miles

Soda Butte Creek to the Canyon:
The Lamar River picks water from the Soda Butte Creek, one of its two largest
tributary streams. From there through a huge wide open valley, a distance of
about 7 miles, the Lamar River is accessible from the Northeast Entrance

This is the heaviest fished section of the Lamar but even so, the fishing is
usually great. The stream has some large boulders and plenty of riffles, runs and
lots of pocket water.

Trout in this section and the lower canyon sections are mostly cutthroats
averaging 9 to 14 inches with some over 18 inches. They may be a few rainbows
and cutbows on the lower end of the Lamar near its confluence with the
Yellowstone River.

Canyon Section:
Below the large meadow section, the river heads into a canyon portion that is
about 2 miles long that can be accessed at the head of the canyon. The stream
gradient increases and there is a lot of fast, pocket water through the canyon.
This section has some huge boulders on its banks and in the stream and
access is difficult in places. The trout in this section are smaller than those in the
meadows as a general rule.

Canyon Section to Yellowstone River:
The Northeast Entrance Road crosses the Lamar just below the canyon. For the
next 5 miles, the stream leaves the road and passes through a section of open
hills and then the heads into another canyon before flowing into the Yellowstone
River. Slough Creek, another large tributary of the Lamar River, empties its water
into the Lamar below the bridge. Slough Creek is covered elsewhere as a major

This section of the Lamar River must be hiked into. There are several ways to get
there. One is at the VIP pullout area at the intersection of Slough Creek Road and
the Northeast Entrance Road located 6 miles east of Tower Junction. You can
fish down the Lamar River from there using an old roadbed that is now a trail.

Two and one-half miles east of Tower Junction on the Northeast Entrance Road
you will find the Lamar Bushwack Trail It is one mile down an unofficial trail to the
Lamar River. Another access is just across the Yellowstone River Bridge one
mile east of Tower Junction. The trail leads north to the confluence of the
Yellowstone River and the Lamar River. It is a half-mile hike.

Cache Creek:
Cache Creek is the first major tributary stream of the Lamar River. The cutthroat
trout in Cache Creek average from 8 to 12 inches long. It can be accessed from
the Lamar River Trailhead on the North East Entrance Road that follows Soda
Butte Creek. It is a 3 mile hike to Cache Creek. Campsites are available on this

Slough Creek:
Slough Creek is a major tributary of the Lamar River. See the Slough Creek page.

If you have never fished this river, you are going to think you died and went to
heaven when you visit the beautiful Lamar Valley. It is one of the most beautiful,
wild places in the United States. Check to make sure there has been no recent
heavy rains from thunderstorms upstream. The Lamar can muddy quickly and
shutdown the fishing for a day or two when this happens.
