1: Fishing at the Wrong Depth

One of the biggest mistakes in Coho salmon Lake Michigan fishing is targeting the wrong depth. Because Coho don’t stay in one layer, it changes its water depth season-wise:

• Spring: shallow water (10–30 ft)
• Summer: deeper zones (40–100 ft)
• Fall: closer to shore again

👉 If you’re trolling too deep or too shallow, you’ll completely miss active fish.

How to Fix Mistake: According to the season in which you are fishing, adjust your depth regularly using downriggers or diving planers.

2: Ignoring When Coho Salmon Run

Many anglers don’t understand when do coho salmon run in Lake Michigan, and this mistake leads to poor timing.

• Peak Season: Spring (March–May)
• Secondary run: Fall (September–October)

Fix: Plan your trips around peak migration periods of silver salmon in Lake Michigan.

3: Using the Wrong Lures

In Lake Michigan coho salmon fishing, lure selection matters a lot.

• Bright spoons (orange, red, silver)
• Flashers and flies
• Small crankbaits

👉 Dull or oversized lures often get ignored.

Fix: Match lure size and color to conditions.

4: Trolling at the Wrong Speed

If you are fishing by boat, then speed is critical in coho salmon fishing Lake Michigan.

👉 Ideal speed: 2.0 to 3.0 mph

Fix: Adjust speed based on fish response.

5: Not Following Baitfish

Lake Michigan coho salmon follow bait like alewives. So follow the bait before you decide to fish in perticular spot.

👉 No bait = no fish.

Best Coho Salmon Fishing in Lake Michigan (Top Spots That Actually Produce)

From my experience, there’s no single “perfect” spot for Coho salmon in Lake Michigan—but there are a few high-producing areas that consistently give anglers an edge, especially if you time your trip right.

Best Coho Salmon Fishing Spots in Lake Michigan

• St. Joseph Harbor – One of the most reliable early-season hotspots. In spring, warmer water pulls baitfish close to shore, and Coho follow aggressively.
• Michigan City Harbor – Known for steady action, especially for beginners. Great mix of nearshore and slightly deeper fishing.
• Chicago Harbor – A popular and productive area where Coho stack up during peak runs, often within easy reach of small boats.
• Milwaukee Harbor – A strong mid-season option, especially when fish start spreading north and moving offshore.

What Actually Matters More Than Location

While these spots are proven, I’ve learned that location alone doesn’t guarantee success. Coho salmon move constantly based on water temperature, baitfish movement, and seasonal migration patterns.

👉 That’s why instead of locking onto one spot, I focus on finding temperature breaks, bait activity, and active fish on sonar. Once you combine the right location with the right conditions, your chances of landing more Coho go way up.

Bottom line: Start with these proven areas, but stay flexible—that’s the real key to consistent success on Lake Michigan.
