Chicago, IL fishing report
Lake Michigan off Chicago keeps anglers busy year-round. Chinook salmon are the marquee target, staging near the surface in warmer months before pushing deeper as summer heat stratifies the water column. Coho show up in good numbers during spring and fall runs, often closer to shore. Lake trout hold in colder, deeper water through summer and become more accessible once surface temps drop in autumn. Smallmouth bass work the rocky nearshore structure — breakwaters, piers, and riprap — from late spring through early fall when water warms into the mid-50s and above.
For salmon and lake trout, trolling with spoons, stick baits, and flasher-fly rigs at depths matching the thermocline is your bread and butter — watch your sonar for the temperature break and concentrate there. Downriggers let you target specific depths precisely. In spring and fall, coho and Chinook push shallower and can be reached with planer boards and shorter lead lengths. For smallmouth, work the concrete and rock structure with tube jigs and drop-shot rigs, especially where current from harbors and river mouths creates baitfish concentrations.
