Background: The Lake Trout is an extremely misunderstood fish. People tend to think of them as a deep mysterious creature that's spread out wide and far and really hard to catch. Traditionally the only thing you ever hear about Lake Trout is folklore created by people who have never caught one. In actual fact, Lake Trout are extremely common, especially in Northern Saskatchewan, and easy to catch any time of year. Rumors about them tasting fishy or being a fatty fish are completely false. In actual fact, Lake Trout is one of the best tasting fishes in the world. It's far superior in flavor to Salmon or Rainbow Trout. Lake Trout is very mild and does not have that skunky smell that salmon and big Rainbows have.
The Ojibwa People called it a Tuladi. The Cree People called it the Namaycush. It's also known as the Mackinaw Trout, Gray Trout, Salmon Trout and nicknamed the Laker. Most people refer to them as the Lake Trout.
There are many lures that Lake Trout will hit but these are the best producers. Silver & Blue and Silver & Green are the best color combination. On sunny days use silver combinations and on dull days use brass color combination. Generally Lake Trout hit way better on bright sunny days with high pressure and limited amounts of wind. From day break to 10:30 am, from 1:00 pm to 4:00 pm and from 7:00 until dark seem to be the best times for Lakers. It's different on many lakes. Sometimes Lake Trout will not feed at all and other days they turn on-and-off like a light switch and only feed for a few minutes but at multiple points during the day.
Lake Trout Fishing after Ice-Out and Early Spring:
Just after ice-out and the first few weeks after, Lake Trout will stay shallow. Many times they will be very close to shore and casting off shore with Cleos and Mepps Cyclopses is very effective. You can also cast off a boat.
Lake Trout will be found at the mouth of rivers, in the rivers, off rocky points and shoals. The very best spot is in dark water off a sand bar. The sun heats up the water on sand bars in the spring and the minnows go up on the sand bars to enjoy the warmer water. Lake Trout will sit off the sand bars in darker water and hit minnows that come to the edge of the sand bar.
Trolling for early spring Lake Trout might seem like an easy thing to do. Just cast a Cleo off the back of the boat and troll. This does work but you can do something to triple your strikes. When you are trolling in the spring, the Lake Trout hear the boat and move out to the sides. They can swim 50 feet or more to give your boat a wide birth. With this in mind, cast out sideways and then let the boat pull the line straight. Then reel in slowly and cast out again. You will find you get way more fish and the Lake Trout usually hit your lure in the first 5 seconds after it hits the water.
The 3-Way Swivel Technique is Best for Slow Trolling Boats:
The 3-way swivel technique below is ten times better then using steel line and it's a lot more fun then using down-riggers. It's really just a modification to the Bait Walker design. It's effective with any deep fish. It can be used for deep Lake Trout, Rainbow Trout or even Salmon and Steelhead on the Great Lakes. It's also effective for Book Trout in lakes but generally in the middle of the summer, Brook Trout stay in the 15 to 35 foot range while other trout will be feeding 50 to 60 feed down. You can also use this method with Walleye. The big trophy female Walleyes will go deep in the summer. Use this method in 20 to 25 feet of water with a worm harness and hit those big trophy Walleyes.
You need a light action rod with 6 or 8-pound test line. You can also use the ultra-thin braided lines. You also need three-way swivels and a 1 or 2-oz weight depending how deep you want to fish, which depends on what time of year it is.
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 3-foot pieces of line to your three-way swivel. Use a 1 or 2-oz. weight on one line and a light lure on the other. Lake Trout like small lures more than big lures. The very best lure is a small Sutton Silver Spoon. You can also use #1 or #0 Mepps, Panther Martins or Blue Foxes. Small Cleos or a small Mepps Cyclopes are also good.
For Walleye, fish 15 to 25 feet deep and use a worm harness with a big fat worm. You can also use light spinners with a long worm hook or small floating Rapalas and Junior Thundersticks.
A 1-oz weight with 6-pound test dark green line is good for fishing down to 40 feet. A 2-oz weight is good for fishing down to 65 feet.
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 deep water 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. 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 3-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. Some 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 feet of line off your reel before you can turn them. Keep your drag set for 6-pound test line and do not horse the fish in.
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. In some lakes the trout feed aggressively 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 its 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. For Lake Trout, try to stay in 30 to 60 feet and close to shore. 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 Pike, 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's 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.
There will be Lake Trout out in the middle of the lake suspended about 40 to 60-feet down. They are usually in close proximity to schools of bait-fish. If you are closer to shore in 40 to 60-feet of water and not catching anything, drop your line down to the bottom so you know how deep you are and then leave your rig at that depth and head out into the open water. In the open water, you will usually catch less trout but they will be bigger. This is not always true. There are occasions where all the trout are out in the open water, especially when the last few days have been hot with a strong wind that keeps changing direction.
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 trout shallow all year.
