Before you launch

Lake Michigan is big water

The pier-head channel is the dangerous part of the trip. An onshore wind stacks waves where the channel meets the lake, and the run home can be far worse than the run out. Check the wind direction against the harbor mouth before you leave the ramp.

Longshore currents and structural rip currents at the piers. Lake Michigan produces more drowning fatalities than any other Great Lake, and most of them happen to swimmers near breakwalls and piers, not to anglers offshore.
Sudden north-to-northwest wind shifts. The lake runs 300 miles north to south, so a northerly builds enormous fetch and turns a flat morning into a five-foot afternoon on the south end.
Seiche events. Wind and pressure can push water to one end of the basin and let it slosh back, producing fast, unexpected water-level swings — one on the Chicago shoreline in 1954 killed several people on a pier.

What to fish on Lake Michigan

Our Michigan fishing guides name spots at or near Green Bay:

Muskellunge · September through November, with late October and November the heavy-fish window

Green Bay Muskie Fishing: The Lower Fox, Sturgeon Bay & Fall Trolling

The lower Fox River, De Pere to the mouth at Green Bay: The center of the program. Wisconsin DNR nets adult muskellunge here every spring, takes eggs from Fox River spawners for the hatchery, and has stocked the river since 1989. Fish run the river below the De Pere dam and out into the bay.

Northern Pike · May and June, September through November, and January through February on Green Bay ice

Northern Pike Fishing on Lake Michigan

Little Bay de Noc and Big Bay de Noc: The top of Green Bay out of Escanaba and Gladstone. Shallow protected weed flats, a huge pike population, and one of Michigan's better tip-up fisheries when the ice sets up.

Smallmouth Bass · Mid-June through early October, with September the peak for size

Smallmouth Bass Fishing on Lake Michigan

Sturgeon Bay and Little Sturgeon, Door County: The Green Bay side of the Door Peninsula. Warm, fertile, rocky and productive — and by far the most heavily fished smallmouth water on the lake, having hosted major national tournaments.

Walleye · Late March through May in the bays, then late June through August on the reef and open-bay pattern

Walleye Fishing on Lake Michigan

The lower Fox River at Green Bay: The single largest walleye spawning run on Lake Michigan. Late March into April, from the De Pere dam downstream. Shoulder-to-shoulder shore access and a boat launch scene that runs day and night.

Yellow Perch · July through October in the southern basin; December through March on Green Bay ice

Yellow Perch Fishing on Lake Michigan

Sturgeon Bay and Sawyer Harbor, Door County: Green Bay side. The best numbers of perch on the lake, and the anchor of a serious winter ice fishery when the bay locks up.

Brown Trout · March through May, with a second window from October into December near harbors and river mouths

Brown Trout Fishing on Lake Michigan

Lake Michigan brown trout are a shallow-water, cold-weather fishery and the Wisconsin shore from Racine to Algoma is the heart of it. From ice-out through May, browns hold inside 20 feet along the harbors and river mouths, catchable from a small boat or a pier.
