Lake Trout Fishing on Lake Huron

The fish that came back

Sea lamprey wiped lake trout out of Lake Huron by the mid-1950s. For fifty years after that, every laker in the lake came from a hatchery. Then something changed: lamprey control got better, the alewife collapsed in 2003, and wild lake trout started showing up in survey nets in numbers that kept climbing. Alewives contain an enzyme that destroys thiamine in the predators that eat them, which causes lethal deficiencies in lake trout fry. With the alewives gone, naturally spawned lake trout survived. Huron now has a largely self-sustaining native population for the first time in three generations.

For an angler that is not an abstraction. It means more fish, spread across more of the lake, in shallower water than the deep-basin hatchery fishery of the 1990s produced.

Shallower than you think

Huron averages 195 feet deep, far less than Michigan or Superior, and its thermocline sits correspondingly higher. Through May and early June, when the surface is 42 to 50 degrees, lake trout hunt in 20 to 50 feet over the clean rock shelves from Rogers City to Drummond Island. You can catch them on planer boards and spoons, on ordinary walleye tackle, within a mile of the launch.

Most anglers skip this because they associate lake trout with downriggers and deep water. Do not. The May shallow bite is the best-kept secret on Lake Huron.

Summer means bottom

By July the surface passes 65 degrees and the fish drop to the basin edge — 80 to 160 feet — and they sit on the bottom. This is when downriggers, dodgers and slow speeds matter. Run 1.7 to 2.1 mph and keep the ball within five feet of the bottom. The single most common mistake is trolling three feet too high; the difference between a blank pass and a double is often that.

Six Fathom Bank in the middle of the main basin is the classic summer target: a big shoal rising abruptly out of deep water, holding bait and fish through the hottest weeks. It is also a long open-water run and deserves a real forecast.

The forage picture

Huron lake trout eat round goby, sculpin, bloater and smelt. Goby especially — they are a bottom-oriented invasive that plugged directly into a bottom-oriented predator’s diet, and it is part of why the recovery took. Practical result: fish bottom-contact presentations. A spoon bouncing off rock, a jig hitting bottom, a dodger dragging through the last two feet of water column. Suspended fish exist, but bottom is the percentage play.

Fall on the reefs

Lake trout spawn on rock reefs in 20 to 60 feet from late September into October. They gather in numbers and they are aggressive. Many Great Lakes jurisdictions restrict or close fishing over known spawning reefs during this period specifically because the fish are so vulnerable, and the specifics change. Check the current rules for the management unit you are in before making a plan around fall reef fishing.

How Huron compares

Superior’s lake trout are wilder, bigger on average and living in deeper, colder, harder water. Lake Michigan’s are still substantially a stocked fishery. Ontario sits between. Huron’s advantage is access: shallow spring fish, protected water around Drummond and De Tour, short runs to good rock, and a population that is still expanding. If you want to catch a lot of lake trout without a 24-mile offshore run, this is the lake.
