Best Fishing Spots in Chicago on Lake Michigan

Chicago sits on the southwestern shore of Lake Michigan — one of the largest and most productive freshwater fisheries in the world. But knowing the lake is full of fish and knowing where to find them are two very different things.

After years of running charters out of Montrose Harbor, I have learned where the fish hold at different times of year. Here is a breakdown of the best fishing spots on Lake Michigan near Chicago.

Montrose Harbor — Our Home Base

Montrose Harbor is where we launch every trip, and it is one of the best starting points for Lake Michigan fishing in the city. The harbor sits at 4400 N Lake Shore Drive and offers easy access to deep water just minutes from the dock.

The area around the harbor breakwall is a productive spot for brown trout and steelhead in the spring and fall. As you move offshore, the water drops quickly — giving you access to the thermocline where salmon and lake trout hold during the summer months.

Parking is available along the outer drive (metered), and the location is easy to reach from anywhere in the city or suburbs.

The Thermocline — Where Summer Salmon Live

During July and August, the surface water on Lake Michigan warms significantly. Salmon and lake trout are cold-water fish, so they drop down to find the thermocline — the layer where warm surface water meets cold deep water. This layer typically sits between 40 and 80 feet down, depending on the time of year and weather conditions.

Finding the thermocline is one of the most important skills in summer charter fishing. We use downriggers to get our baits to the exact depth where the fish are holding. When you dial in the right depth, the action can be fast and furious.

The North Shore Drop-Off

As you head north from Montrose Harbor along the Illinois shoreline, the lake bottom drops off sharply just a mile or two offshore. This underwater structure creates a natural feeding lane where baitfish concentrate — and where salmon and trout follow.

The north shore area is particularly productive for Chinook salmon in late summer and fall as fish begin staging for their spawning run. We often run 5 to 10 miles north of the harbor to find the best concentrations of fish.

The South Shore and Indiana Border

Heading south from Chicago toward the Indiana state line, the lake opens up into some excellent open-water fishing territory. This area can hold large numbers of coho salmon in the summer and is worth the run when fish are concentrated there.

The south shore also offers good brown trout fishing in the spring, particularly near the river mouths and harbor entrances where trout stage to feed on baitfish.

Offshore Structure and Humps

Lake Michigan has underwater humps and structure that do not show up on a basic map but are well-known to experienced charter captains. These areas concentrate baitfish and, in turn, attract salmon and trout year-round.

Finding these spots takes years of experience and a good understanding of the lake's bottom topography. It is one of the reasons booking with an experienced captain makes such a difference — we know where to go based on current conditions, water temperature, and time of year.

Seasonal Location Guide

Fish move throughout the season, so the best spots change month to month:

• April–May: Brown trout and steelhead near shore, around harbor entrances and breakwalls

• June: Coho salmon moving offshore as water warms; steelhead still active

• July–August: Chinook and coho on the thermocline, 3 to 10 miles offshore

• September–October: King salmon staging near shore for the spawn; best all-around fishing of the year

• October: Late-season coho and brown trout; some of the biggest fish of the year

Why Book a Charter Instead of Fishing from Shore?

Shore fishing in Chicago is popular, but it limits you to the species and sizes that come close to the bank. A charter gets you out to where the big fish live — the open lake, the thermocline, the offshore structure.

On the ROYALTY, we cover water efficiently and put you on fish based on real-time conditions. We bring the electronics, the tackle, the local knowledge, and the experience. You bring the enthusiasm.
