Salmon and smallmouth season hits stride on Indiana's Lake Michigan shoreline

What's biting

What's next

The First Quarter moon on June 21 sets up productive feeding windows at first light and in the final two hours before sunset over the coming days. Plan salmon launches before 6 a.m. to catch the best morning window before boat traffic picks up and surface glare sets in.

For Chinook trollers, the next two to three days represent a prime late-June opportunity before rising surface temperatures push kings into deeper thermal refuge. Work the 80–120-foot contours off the Michigan City and Burns Harbor areas, targeting the thermocline where cooler water concentrates baitfish. Spoon rigs and meat combos in blue/silver, chartreuse, and glow patterns are reliable producers at this stage of the season. Downriggers set 40–60 feet down are a sound starting point when surface temps are warm.

Coho continue to track alewife schools in shallower water — typically 30–60 feet — making them accessible to smaller-boat anglers. The WI DNR Lake Michigan Fishing Report's documentation of elevated alewife survival rates, which fueled record 2024 coho catches, suggests stocked fish have had solid forage support heading into 2026.

Nearshore smallmouth bass fishing should be productive through the weekend. Tactical Bassin's recent Great Lakes smallmouth coverage points to swimbaits as the call in wind-driven open-water conditions — the Dark Sleeper pulling bigger fish, with the Spark Shad as a finesse follow-up when bites slow. Work rocky breakwalls, pier pilings, and sand-to-rock transition zones. Calm mornings can produce topwater action before afternoon winds pick up.

Yellow perch, a reliable option for anglers wanting steady action, tend to drop into 25–40 feet of water by late June. Small jigging spoons tipped with minnow heads over hard-bottom areas are the standard approach. IL/IN Sea Grant's nearshore buoys are worth a check before every launch — afternoon southwest winds in late June can build wave heights quickly, and conditions that look manageable at the dock can deteriorate within an hour offshore.

Context

Late June is historically one of the stronger periods for Lake Michigan salmon action along the Indiana shoreline. As surface temperatures climb through the mid-60s toward 70°F, Chinook retreat toward the thermocline while coho remain accessible in an intermediate depth band. The Indiana shoreline's proximity to deep water — the southern basin drops sharply offshore of Michigan City — means fish do not have to travel far to find thermal refuge, a structural advantage over shallower mid-lake sections.

The WI DNR Lake Michigan Fishing Report provides the most informative benchmark available this cycle. Wisconsin's 2024 season was exceptional: record coho and the strongest Chinook numbers since 2012, with biologists attributing the success directly to recent strong alewife year-classes boosting stocked-fish survival. Lake Michigan is managed cooperatively across states, and alewife population health is a lake-wide dynamic — Indiana anglers benefit from the same forage base that drove those Wisconsin results.

Whether 2026 tracks 2024's numbers is unknown without current Indiana-specific creel or stocking survey data. The absence of local charter reports and tackle-shop intel in this cycle is a meaningful data gap; anglers with recent time on the water off Michigan City, Portage, or Hammond are in a far better position to benchmark current conditions than aggregate regional sources can provide.

For smallmouth bass, late June in the Great Lakes region typically marks the transition out of post-spawn recovery into active summer feeding. Fish that were guarding beds in late May and early June are now forage-focused, which aligns with Tactical Bassin's Great Lakes coverage showing aggressive strikes on swimbaits during this seasonal window. Fishing the Midwest notes that versatility — willingness to shift species or presentation based on daily conditions — tends to separate consistent producers from one-dimensional outings during open-water summer stretches.
