Spring salmon picking up along Indiana's Lake Michigan shore

What's Biting

What's Next

With the waning crescent moon in the sky this week, low-light dawn windows give anglers the strongest edge on Lake Michigan. Salmon and steelhead are light-sensitive predators, and reduced moon glow tends to push fish shallower and into a more aggressive feeding mode before full sunrise. Plan your launch to be on the water at first light, with lines set well before the sun clears the horizon.

The trolling setup described in recent Lake Michigan forum reports — Bandits back 35-40 feet at 1.8-2.0 SOG, supplemented by jets and spoons per the Michigan Sportsman Forum — is a proven early-May template for southern Lake Michigan and should remain effective through the weekend. Depth flexibility is key as spring progresses: Chinook tend to push deeper as surface temperatures climb, while coho and steelhead historically hold shallower through mid-May. If fish appear on the sonar but won't commit, try staggering lines across a broader depth band to isolate the active layer.

No buoy readings are available for this reporting window. IL/IN Sea Grant maintains three nearshore Lake Michigan monitoring buoys that publish real-time wave height and surface temperature data — worth checking before you trailer the boat. A few degrees of surface temperature change at this stage of spring can shift where fish stack in the water column significantly.

Looking toward Memorial Day weekend — historically the highest-pressure salmon window on the Indiana shoreline — conditions will continue evolving quickly. If surface temperatures push into the mid-50s°F range over the coming weeks, expect Chinook to begin dropping toward deeper structure while coho and steelhead remain accessible closer to the pier heads and nearshore breaks. Yellow perch, a consistent mid-May nearshore species along the Indiana coastline, offer a productive secondary target on mornings when the salmon bite slows. Pier and harbor fishing with small jigs tipped with minnows can produce steady perch action alongside the trolling bite.

Context

Mid-May is one of the most anticipated stretches of the fishing calendar on Indiana's Lake Michigan shoreline. Chinook and coho salmon, steelhead, and lake trout typically reach their spring nearshore peak from late April through Memorial Day weekend before rising surface temperatures push fish into deeper offshore structure through the summer months.

The WI DNR Lake Michigan Fishing Report documented an exceptional benchmark in 2024: record coho harvests exceeding 210,000 fish lake-wide and Chinook numbers topping 160,000 — the best Chinook showing since 2012. The WI DNR attributed both records to strong alewife year classes that dramatically improved the survival of stocked salmon. Alewife abundance is the single biggest wild variable in Great Lakes salmon recruitment, and those same cohorts are now entering their peak harvest years for 2026. Whether this season sustains that momentum depends on alewife overwinter survival, which is not reflected in the current data available.

The trolling parameters surfaced in the Michigan Sportsman Forum — 18-20 feet, stickbaits back 35-40 feet, speeds of 1.8-2.0 SOG — are consistent with what is typically productive for southern Lake Michigan in this window. Fish are still holding in the mid-depth band, not yet pushed to their deep-summer haunts, and the moderate-depth trolling approach with stickbaits, spoons, and jets has been a reliable early-May formula for decades on this end of the lake.

Without confirmed buoy temperature data, it is not possible to say definitively whether spring 2026 is running early, late, or on schedule relative to long-term norms. Based on the available angler intel, conditions appear consistent with a typical mid-May setup for the Indiana shoreline — no dramatic early or late signals emerge from this reporting window.
