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 Port Washington:

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

Brown Trout Fishing on Lake Michigan

Sheboygan and Port Washington: Classic Wisconsin brown water. Troll the 10 to 25 foot band along the shoreline in April, working out from the harbor entries.

Chinook Salmon · Late June through Labor Day, with the staging run building through the last two weeks of August

Chinook Salmon Fishing on Lake Michigan

Sheboygan and Port Washington: The Wisconsin side runs colder and shallower on the same calendar. Kings hold tighter to the 100 to 200 contour and the reef complex south of Sheboygan concentrates alewives into July.

Coho Salmon · Late March through May in the southern basin, then north to Ludington and Manistee by July

Coho Salmon Fishing on Lake Michigan

The April and May coho run in southern Lake Michigan is the most beginner-friendly big-water salmon fishing in America — the fish school tight in the top 25 feet within a few miles of Chicago and the Indiana ports. A 4- to 6-pound coho on light tackle in 45-degree water is a better introduction to Great Lakes trolling than any king trip.

Lake Trout · May and June on shallow rock, July through September deep, plus a fall reef concentration

Lake Trout Fishing on Lake Michigan

Lake Michigan lake trout are the most dependable fish in the lake — they are there in numbers when the kings are not, and they will bite in flat, hot, bright conditions that shut a salmon program down. Fish the reefs and the deep basin edges, and expect to work 100 to 180 feet down from July on.

Lake Whitefish · December through March through the ice; October through April from a boat in Grand Traverse Bay

Lake Whitefish Fishing on Lake Michigan

Grand Traverse Bay is the marquee whitefish water on Lake Michigan and it produces from a boat in open water as well as through the ice, which very few whitefish fisheries do. Fish 60 to 120 feet on the deep flats and the fish are there most of the year.

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

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

Lake Michigan's main basin is not muskie water, but Green Bay holds a genuine trophy fishery for Great Lakes spotted muskellunge, rebuilt by stocking since 1989. Fish the lower Fox River, the southern bay and the Door County bays in fall, and understand that this is a big-fish, low-numbers fishery that stocking still holds up.
