What Lake Huron at Lexington offers anglers

Lake Huron at Lexington is a working-class walleye and yellow perch fishery tucked into Michigan's Thumb, where the lake meets the Lexington harbor and the Au Gres River system. The water here is shallower and warmer than the open lake, which means the fish hold predictably and the season runs longer than it does offshore. You're fishing a transition zone—part protected harbor, part open lake—and that matters for where you'll find fish and when.

The harbor itself runs roughly north-south, with a breakwater on the west side and a sandy bottom that drops gradually toward the main lake. Walleye move into the shallows at dawn and dusk, especially in spring and fall. Yellow perch school tightly year-round and are often the easier catch, though they run smaller than the walleye. The Au Gres River inlet, on the south end of the harbor, concentrates both species during spring spawning runs and again in fall when they're moving between river and lake.

Key Takeaways

  • Lexington harbor holds walleye and yellow perch in predictable shallow water, making it a good choice when you want to avoid the open lake.
  • Spring and fall are peak seasons for walleye; perch bite year-round but are most abundant in summer and early fall.
  • The Au Gres River inlet concentrates fish during spawning runs and seasonal movements between river and lake.
  • Public access is available at the Lexington State Harbor, which has a launch ramp and parking; arrive early in summer.

Spring walleye in the shallows

From late April through May, walleye move into water 6 to 12 feet deep to spawn, and Lexington harbor is one of the easier places on the Thumb to intercept them. Fish the breakwater edges and the shallow flats on the harbor's east side at first light and last light. Jigs tipped with live shiners or crawlers work best; cast parallel to the breakwater rather than straight out, and work the lure slowly—walleye in cold water don't chase.

The Au Gres River inlet is worth a dedicated trip during this window. Walleye stack up waiting to move upriver, and you can fish from the bank or from a small boat in the inlet mouth. Water temperature is the trigger: when it hits 48 to 52 degrees, the bite turns on. Check the NOAA Great Lakes water temperature forecast before you go; it's more reliable than the air temperature.

Summer perch and walleye mixed

By June, the harbor warms and walleye move deeper or offshore, but yellow perch become the main event. They school in 8 to 16 feet of water and will bite all day, though early morning and late afternoon are still better. Small jigs—1/16 to 1/8 ounce—with live shiners or perch eyes work well. You don't need to cast far; perch are often right off the dock pilings and the breakwater base.

Walleye don't disappear in summer; they just move to the deeper edges of the harbor and the first drop-off into the main lake. If you want to target them, fish the deeper water (16 to 25 feet) at dawn or dusk, or switch to live bait rigs and fish the bottom. Many anglers focus on perch in summer and save the walleye hunt for spring and fall, when the fishing is more consistent.

Fall movement and the Au Gres connection

September and October bring a second strong walleye bite as fish move back into the shallows to feed before winter. The harbor fills up again, and the Au Gres River inlet becomes a funnel. Fish the same shallow structure you worked in spring—breakwater edges, flats, inlet mouth—but expect the bite to last longer into the day because the water is cooling and walleye are more active.

Fall is also when perch are fattest and most abundant. They school heavily in the 10 to 14-foot zone and will bite steadily from mid-morning through afternoon. If you're new to the harbor, fall is the most forgiving season: the fish are concentrated, the weather is usually calmer than spring, and you have more daylight to learn the bottom.

Winter fishing and ice access

Lexington harbor freezes solid most winters, usually by late December, and ice fishing for perch and walleye is popular. The harbor bottom is well-mapped by local anglers, and the shallow water means you're never far from structure. Perch bite steadily through the winter under the ice; walleye are more seasonal but can be caught on live shiners fished near the inlet or the deeper edges of the harbor.

Ice safety is critical: the harbor ice is usually thick enough by mid-January, but check with local bait shops before you venture out. The Lexington State Harbor office can also tell you about current conditions. Avoid the inlet area until the ice is thick—current keeps it thinner than the rest of the harbor.

Public access and facilities at Lexington State Harbor

The Lexington State Harbor is the main public launch point. It has a concrete ramp, parking for about 30 vehicles, and a small marina building with restrooms. The ramp is well-maintained but gets crowded on summer weekends and during the perch bite in early fall. Arrive by 7 a.m. if you're going on a Saturday or Sunday in July or August.

There is no overnight camping at the harbor itself, but the town of Lexington has a few small motels and a campground a short drive away. Gas and bait are available at shops in town. The harbor is open year-round, though the ramp is not plowed in winter—ice fishing access is from the ice itself, not the ramp.

Tackle and technique for Lexington harbor

Walleye respond best to live bait: shiners, crawlers, and minnows. Jigs in the 1/8 to 3/8-ounce range work year-round; tip them with live bait and work them slowly along the bottom or suspend them just above it. For perch, go smaller—1/16 to 1/8-ounce jigs—and use perch eyes or small shiners. Perch will also take small spinners and spoons if you're in a hurry or want to cover water.

A 6 to 7-foot medium-light rod with 6 to 8-pound braided line is standard for both species. Walleye fishing benefits from a sensitive rod so you can feel the bottom and detect light bites. Perch fishing is less technical, but a light rod makes the small jigs easier to work. If you're new to the harbor, ask at the bait shop what's working that week—conditions change, and local knowledge saves time.

Frequently Asked Questions

What's the best time of year to fish Lexington harbor?

Spring (late April through May) and fall (September through October) are peak for walleye. Yellow perch bite year-round but are most abundant and easiest to catch in summer and early fall. Winter ice fishing is also productive if you have experience on the ice.

Do I need a boat to fish Lexington harbor?

No. You can fish from the breakwater, the harbor docks, and the Au Gres River inlet from shore. A small boat gives you access to deeper water and more structure, but many anglers catch plenty of perch and walleye from the bank, especially in spring and fall.

How far is Lexington from other Sanilac County fisheries?

Lexington is on the lake itself, about 20 minutes north of Port Sanilac and roughly 30 minutes from the Cass River system. If you're exploring the Thumb, you can fish the harbor in the morning and move inland to river fishing in the afternoon.

What Michigan fishing license do I need?

You need a current Michigan fishing license. Residents and non-residents can purchase daily, 3-day, or annual licenses through the Michigan Department of Natural Resources website or at any bait and tackle shop. Walleye and perch are both open year-round in Lake Huron, though bag limits apply—check the current regulations before you fish.

Is the Au Gres River worth fishing separately from the harbor?

Yes, especially during spring and fall spawning runs. The river holds walleye, northern pike, and some smallmouth bass. It's a different fishery from the harbor—narrower, more current, more structure—but the inlet mouth is where harbor and river fish overlap, making it a natural starting point.
