Fly Fishing Penobscot River Maine
The Penobscot River is the largest river in the state of
Maine. It flows from near the Canadian line for almost
350 miles. The river has several species of fish that
can be taken on the fly but the trout and landlocked
salmon fishing is best. It exist in the East and West
Branches of the Penobscot River.
The East Branch starts as a small streams that flows
from East Branch Pond. From there it flows into
Matagomon Lake and Grand Lake Matagomon. Part of
this upper section of the river flows through Baxter
State Park and is very remote. Below Grand Lake
Matagomon, the river is wide and easier to access. The
flows depend on the releases from the dam.
The West Branch of the Penobscot River is one of the
best landlocked salmon streams in the United States. It
flows from the East arm of Seboomook Lake. From the
dam there it flows into Chesuncook Lake and
Ripogenous Lake and continues on from the
Ripogenous Dam. This river has water falls, whitewater
and very deep pools. Some sections have long runs
and beautiful sections of riffles. It has native brook
trout in addition to its salmon. It's a very beautiful
The section of the river from the Ripogenus Dam to
Abol Bridge is just one of the most popular sections for
fly fishing. The Ripogenus Gorge holds wild landlocked
salmon and brook trout. In many sections of the river
the water falls and pools that are deeper than one's
head prevent wading. Most of the fishing there is done
The salmon season kicks off with the smelt run. It is
difficult to predict the exact time it starts but when it
does, fishing can be fantastic.

Fly Fishing Guide to the Penobscot
The fishing first and foremost depends on
where you are fishing. The water varies
drastically. The river is near Maine's highest
mountain, Mount Kathadin. It is sometimes
visible in the background. The stream flows
mostly through forest. The area is known for
its wildlife which includes eagles, bear, deer
This isn't a very easy river to fish. It has just
about every type of water that's imaginable.
You could use about every techniques and
method of fly fishing that exist in the river
depending on where you fished and what
you fished for.
Although the season starts the first of April,
the ice may not be melted at that date. It is
usually a little later when the smelt run gets
underway before the fishing gets hot. During
the smelt run, salmon usually take streamers
that match the smelt eagerly. This can
provide some of the Penobscot River's best
The West Branch section below the
Ripogenus Dam downstream to the Abol
Bridge is a very rough stretch of water. It
provides great wild, landlocked salmon
fishing but is tough to fish by boat or from
the bank. It also provides some great
brook trout fishing. The water changes
from large rapids to long sections of riffles
and runs with deep pools between
sections. This section of the river has a lot
of white water rafters but they don't bother
the fishermen as much as you would think.
Kayakers and rafters out number anglers
by a large amount.
The water in the West Branch stays cool
all summer long. Even though there are
many rapids and sections of water that is
impossible to wade, there is also sections
that are easy to wade. This is a big river
and one could wade for days and not fish
the same section twice. Beware of the
areas that are dangerous to wade and
beware of the releases from the dams on
the rivers. They can change the flows
The season starts the first of April but the
early season can be unpredictable.
Fly fishing the Penobscot River normally
gets good about the first of May.
Summertime continues the best season for
Early Fall can be good.
Penobscot River Hatches and Trout
Most of the mayfly hatches occur from May
into the first half of June. The middle of June
starts some huge and prolific caddisfly
Little Black Stoneflies are the first hatches to
occur on the Penobscot River. The problem
is that they are usually all gone by the
opening of the season.
There are several species of Little
Blue-winged Olives that hatch during the
year. They start in April and usually a peak
around the middle of May. These last through
most of June and then slack off until about
the middle of August. They fall hatches last
through September. There's a Great Olive
Winged Dun locally called the Hexagenia
hatch that starts about the middle of June
and can last through most of July.
Quill Gordons start hatching about the same
time the season opens in April and last until
the middle of May. Hendrickson mayflies
hatch about the same time or from about the
first of May through the first week of June.
March Browns start about the first week of
June and last until near the first of July. Light
Cahills start about the first of June and last
on into the middle of July. All of the above are
clinger mayflies that will be found in the
moderate to fast water.
Little Yellow Stoneflies hatch from about the
first of June into the first of July. These
stoneflies are called Yellow Sallies by some
There are several species of Spotted
Sedges and Cinnamon Sedges. These
caddisflies hatch from about the middle of
April all the way through September. There
are also lots of Green Sedges that hatch
during June and July. Imitations of their
larvae, often called Green Rock Worms,
are very effective.
Ants, beetles and grass hoppers are all
important terrestrial insects. These
normally become important around the
middle of July. They can be found along
the streams until as late as the end of
September. Dragonfly nymphs can also be
effective in some areas.
You definitely need streamers to match the
smelt if you fish early in the season. Also
streamers that imitate sculpin work great.
Our Perfect Fly Yellow Marabou Sculpin
and White Marabou Sculpin work great in
this stream according to our customers.
