How To Zero In On Lake Trout

Lake trout are synonymous with Northern Ontario, as the magnificent sport fish flourish in the same deep, clear, picture-postcard wilderness waters that distinguish the province.  Ontario is blessed, as well, to have one-quarter of all of the lake trout lakes in the world.  So it is no wonder that so many anglers travel to marquee waters like Georgian Bay, Lake Muskoka, Panache Lake, Lake Temagami, Lake Superior, Lake Dayohessarah, Lake Nipigon, Anishinabi Lake, Clearwater Lake and Lake Vermilion to name but a few, to catch the fish of their dreams surrounded by beauty.

Because lake trout thrive in the colder water temperatures found in the deeper portions of the lake, however, they can offer a unique challenge to anglers. Should you start fishing in 30, 40, 50, or even as much as 60 or 70 feet of water?

Well, the answer to that question is quite simple if you remember that lake trout — like all fish — are poikilothermous or cold-blooded. This means their body temperature is the same as the temperature of the water in which they are swimming.  It is important to remember, as well, that lake trout associate strongly with water temperatures, typically ranging between 49°F (9°C) and 54°F (12°C).  Find this band of water that offers the dwellers-of-the-deep their preferred temperature and you’re going to catch fish.

To help you do this, click on this short video I shot the other day on one of my favourite lakes in Northern Ontario, and watch how easy it is to pinpoint the lake trout of your dreams.
