NAMES: Lake trout, Grey trout, Mackinaw trout
SCIENTIFIC NAME: Salvelinus namaycush
IDENTIFICATION: Lake trout are a medium to dark gray or olive color
with white worm-like wavy marks on their backs and on top of the
head. Occasionally, they have bars or spots along the side mainly
tinged with red. Lake trout also are the only trout in Ohio with a
deeply forked tail.
RANGE & HABITAT: Lake trout are native to the Great
Lakes and prefer deep, coldwater lakes throughout North America.
They are usually found offshore in deep, well-oxygenated water. In
Lake Erie, lake trout are usually not found in Ohio waters, but can
be found in low numbers in the East Central and Eastern basins.
LIFE HISTORY: Lake trout spawn on offshore shoals and reefs in the
fall. Eggs hatch in the spring and young lake trout usually move to
deeper water after a short time. Adult fish are opportunistic
feeders their diet consisting of aquatic insects, crustaceans, and a
range of fish species, including small lake trout. The lake trout is
a slow growing, long-lived species that does not become sexually
mature until age seven or eight. Lake trout populations have been
greatly reduced over much of their range due to their susceptibility
to parasitism by the sea lamprey.
ADULT SIZE: Lake trout average between 20 and 24 inches and 3 to
6 pounds, but are capable of reaching 50 pounds. Ohio's state record
fish weighed 16 pounds and 11 ounces.

Your Thinking:
It takes
a bit more skill to catch Lake Trout, especially in the summer-time.
For years people have been using trolling rods with thick wire line
and lots of weight to fish deep. It's the exact opposite ideology if
you want to catch them. Thick heavy line causes more friction with
the water, thus it is harder to go deep. Plus heavy trolling rods
are not sensitive enough to feel a small fish hit your lure when you
are fishing 60 feet deep.
You need
a light action rod with six pound test line. You also need three-way
swivels and a 2 oz weight for fishing down to 50 feet or a 3 oz
weight for fishing down to 80 feet.
Below is
a diagram showing the setup:
By using light
line, the line has less friction with the water and slices
through so that your line goes down to the bottom without
having lots of line out. Tie two 4 foot pieces of line to
your three-way swivel. Use a 2 oz. weight on one line and a
light lure on the other.
Lake
Trout like small lures. Use #1 or #0 Mepps or Blue Foxes.
The absolute best lure for Lake Trout is the Sutton Silver
Spoon. Try to find a 2 inch weightless. Your local bait
store will have to order them for you. It's very rare to see
them on the shelf.

Trolling
Slow:
You only
want to move just fast enough for your lure to work and no faster.
If your boat is moving too fast, it will be very hard to find the
bottom of the lake. If you are using a boat with a bigger motor and
it's hard to keep slow, try back trolling.
Finding
the bottom:
The most
important aspect of Lake Trout fishing is letting out line to get to
the bottom. DO NOT JUST LET YOUR LINE OUT UNTIL IT HITS BOTTOM. Hold
the rod in one hand with the bail open. Let the line run through the
palm of your other hand and grip the line. Once the boat starts
moving and you have a good straight troll going, open your hand with
the line then close it again. This way you can let out a foot or two
of line at a time. Get a rhythm going. Open, close, open, close.
Your rod tip will bounce up and down as you release little bits of
line at a time. The rhythm of your rod tip bouncing will be
disrupted when your weight hits the bottom of the lake. When this
happens, reel up a foot or two. The purpose of this procedure is to
keep your three way swivel setup from getting tangled.
Trout
are funny when it comes to hitting your lure. Small ones will hit
and then take off so you know you have a fish on. The really big
trout will hit the lure and slowly swim away. They are so big they
don't know they're hooked. So if you get a snag, make sure it's not
a fish before you start toughing on your line. If it's a big trout,
loosen the drag on your reel because they will go nuts and strip a
100 yards of line off your reel before you can turn them.
Weather:
In the
summer time, Lake Trout hit best in the morning between first light
and 10:30 AM. They will hit better if the surface of the water is
dead calm and it's a clear sky with high pressure. Any other
conditions will cause them to slow down. If it's early spring, the
trout seem to feed in other parts of the day, thus they are easier
to catch. In some lakes the trout feed before dark.
Structure
and wind:
Take a
close look at the structure of the shoreline and try to extend the
elevation patterns into the lake. If you see a cliff, odds are the
water is deep at it's face. If you see a string of islands, odds are
there is a shallow shoal that runs between them. Trout like
drop-offs so you would want to troll parallel to the string of
shoals and not over them.
When you
drop your line to the bottom, count how many times you let out line.
You can get a good estimate of the depth. Try to stay in 40 to 60
feet of water. If you come across a spot and catch a trout, odds are
there are more of them there. The wind is very important when trout
fishing. Traditionally for warm water fish like Walleye or Musky,
you would fish on the side of the lake were the wind is blowing. The
logic being that the fish follow the surface food that is being
blown in. With trout it is the exact opposite. The wind also blows
the warm surface water which does not hold enough oxygen for the
trout. Thus fish the side of the lake where the wind is coming from.
Depth:
In the
Spring, the Lake Trout will be right up to the surface. As the water
starts to warm up with the changing weather, the trout start to go
deeper. Here is the approximate depth for different times of year.
This is not true for all lakes. Some smaller spring fed lakes will
have Lake Trout shallow all year.
Just
after ice-out --> Between 10 feet and the surface
Mid Spring --> About 35 to 45 feet deep
Late Spring --> About 50 to 65 feet deep
Summer --> Summer is the tricky part. Many believe that the Lake
Trout go to the deepest part of the lake and stay dormant. In actual
fact, the Lake Trout stay suspended in 53° thermal layers. Why are
they there? That's where all the bait fish are. Lake Trout feed on
White Fish and Suckers which they find suspended in schools. There
will be trout on the bottom but they are not feeding as much. When
they do want to feed, they come shallower to feed on suspended bait
fish.
Depth
Finder:
It's
good to have a depth finder so you can map the schools of bait fish
that are suspended. When you do come across a school, troll around
the outside of the school. The Lake Trout sit right underneath the
school waiting for weak or injured fish to venture outside the
school. Out in the middle of the lake, you will find these schools
of bait fish in the 40 to 60 foot range. It's different on most
lakes but this is a good place to start.
