Yellowstone National Park and
Surrounding Waters

Streams Inside Yellowstone National Park:
(See streams outside the park at the bottom of the page)

Firehole River:
The main part of the Firehole River water temperature is still too warm for good
fishing but that will be changing very soon. The upper Firehole headwaters and
some of its small tributaries can be fished now. This includes the Little Firehole,
Nez Perce creek, etc. The later it gets into the month of September, the better the
Firehole will fish.

Gibbon River:
The lower section of the Gibbon River (below the falls) downstream to the meadows
is okay but still a little warm. The upper Gibbon River (above the falls) is in good
shape. Fish are being caught from the falls up to and above the meadows and
Norris Geyser Basin. The rainbows and brook trout are small in the uppermost
sections but there are lots of them and they are fun to catch.

Madison River:
The Madison River (in the park) is still a little too warm for good fishing
opportunities but that going to change very soon. Currently, it is ranging from a low
of 64 to 70 degrees during the hottest part of the day. If you do fish it, we suggest
you limit your fishing to early or late hours. A good rule of thumb, is too not fish if
the water temperature is above 67 degrees. It usually isn't, until mid day. This will
be changing and getting cooler as the month progresses.

Gallatin River:
The Gallatin is in good shape and fishing well from top to bottom. It isn't exactly as
easy to fish as it was during the first part of the summer. The hatches have slowed
down to Pale Evening Duns, some Yellow Quills, and lots of caddis. The fishing
conditions will get tougher within the next week or two, but all depending on the
weather, of course.

Gardner River
The Gardner River is in good shape and will only get better the later in the month it
gets. Browns will move out of the Yellowstone River into the Gardner to spawn. You
will still find some Little Yellow Stoneflies, Spotted Sedges, Pale Evening Duns and
a few other insects hatching from the headwaters above the falls all the way
downstream to the Yellowstone River. Terrestrials will work great, especially in the
lower section where the river is surrounded by lots of high grass. The hoppers will
still be present even after the first or second frost.

Yellowstone River (Canyon Section):
The water has cleared and is in good shape with Golden Stoneflies, Little Yellow
Stoneflies, Spotted Sedges, Pale Morning duns, and others. Tough to get too, but
there will be plenty of fish to catch for the ones brave or stupid enough (depending
on your age and heath) to fish.

Yellowstone River (Black Canyon):
LIttle Yellow Stoneflies are still hatching along with other aquatic insects such as a
few smaller, size 18 PMDs, Spotted Sedges, Green Sedges, Pale Evening Duns,
and other insects. In another two or three weeks, you could begin to see some
October Caddis. This is a good late summer destination but takes a little hiking to
get to its best water.

Yellowstone River Above Yellowstone Lake and below the Lake to the
Yellowstone Falls.
This section of the river will be in good shape for another couple of weeks. There
are still some PMDs, Spotted Sedges, Green Sedges, Pale Evening Duns and a
few others aquatic insects around. There will be plenty of terrestrials, especially
hoppers. Many of the Cutthroats will have moved back into the lake but there will
still be resident cutts in the river to catch.

Lamar River:
The Lamar River will be pretty well beat to death on the lower end where the road
follows along nearby. Also, upstream thunderstorms will still affect it every once
in a while, but it should remain in good shape for most of the month of September.  
Spotted Sedges, Little Yellow Stoneflies, and a fall hatch of March Browns will be
around for a few more days. Ants and beetles are always worth imitating. The
canyon area near the Yellowstone River confluence is fished less than the visible
part along the highway. Better, hike a few miles up the stream from the point it
departs the highway at the Soda Butte confluence. The water upstream of that
point is fished far less.

Soda Butte Creek:
The creek should still be in good shape with some fish still being caught, but they
will be more difficult to catch than they were in July. Those in the meadows will have
seen a lot of flies and have sore lips. The upper section above Ice Box Canyon
will still be in good shape but the cutts will average a smaller size. You can fish
Soda Butte far upstream of the Ice Box canyon. The higher you go, the better the
fishing. At the uppermost bridge crossing, you will have to hike and/or wade
upstream to fish it but it is normally very good. Just don't expect many fish over 12
to 14 inches, if any.

Slough Creek:
The creek will still be in good shape with lots of trout still being caught in the upper
and lower sections, but like the Soda Butte and lower Lamar, they will be tougher to
catch. I know for a fact it will still be busy most of the month of September in its
upper sections. We have set up numerous anglers planning to fish it during this
month.There will still be is a ton of insects hatching including some Gray Drakes,
Green Drakes, Small Western Green Drakes, Little Yellow stoneflies,
Spotted Sedges, Green Sedges, small size Pale Morning Duns, and Ants, Beetles
and hoppers. The numbers of insects will dwindle during the next two or three
weeks.

Lewis River:
The Lewis River is now in good shape. Early September is a great time to fish the
Lewis Canyon and upper sections of the river. Several insects will still be hatching.
The slower, smoother sections you can see from the road are more difficult to fish
than the fast water sections. Few anglers go to the trouble to hike up the Lewis.
The river has some good size brown trout, so don't get fooled. Also, we have found
late August and early September a good time to find a flying ant fall. That really
turns the trout on.

Snake River:
The Snake will be in good shape and fish are being caught by the few that are
fishing the river. There are many miles of this river in the park that are rarely
fished. It requires hiking and few go to the trouble to fish the many miles of the
stream that all exist off road. Browns will start moving out of the lake upstream into
the park near the end of the month.Like the Lewis, the slower, smoother sections
are more difficult to fish than the fast water. Most of the upper sections consist of
fast water. There are some open meadows where the water flow slower and
smoother.

Bechler River:
The Bechler River of the Cascade Corner of the park is in good shape and is
another of the park's streams that is rarely fished. Most that do fish it are locals.  
August and September are the best times to fish the river and in particular, its
meadow sections. The meadows hold some good size fish but they aren't exactly
push overs. It requires a good hike to reach the meadows and when you do get
there, you will need to make som good presentations and to match the hatch.
Smaller size 18 PMDs, Pale Evening Duns, Spotted, Green Sedges, Blue-winged
olives and terrestrials - ants, beetles and hoppers, are some of the flies you will
need depending on the time you fish it.

Fall River:
Like the Bechler, the Fall River of the Cascade Corner of the park is in good
shape. Hiking is required to fish just about all of the river and from now through
most of September is the best time to do it. PMDS, Pale Evening Duns, some Flavs
(Small Western Green Drakes, Little Yellow stoneflies, Spotted and Green
Sedges and terrestrials are flies you should have on hand. You probably won't see
another angler.
