September on Lake Michigan. As the leaves start to turn, so does the fishing action, with Chinook and Coho salmon making their spawning runs. If you thought August was exciting, September brings a whole new level of adrenaline to the water.
In this blog, I’ll share why September is prime time for targeting these iconic salmon species, how their behavior shifts, and tips to maximize your chances of a successful trip. Let’s get to it!
What Makes September Special for Salmon Fishing?
September marks the start of the annual salmon spawning run. Both Chinook (King Salmon) and Coho Salmon leave the deep waters of Lake Michigan and head toward their spawning grounds, typically in rivers and streams. This migration makes them more accessible to anglers, as they often gather near river mouths and harbor areas.
The key difference this month? Their feeding behavior slows as they focus on spawning, which means catching them requires skill, strategy, and a bit of patience.
Spotlight on Chinook Salmon
Chinook salmon are the heavyweights of Lake Michigan. By September, they’re at their most impressive sizes, with many tipping the scales at 20-30 pounds or more. However, they’re no longer feeding aggressively, so catching them requires the right approach.
Tips for Catching Chinook in September:
- Use Flashy Lures: Bright spoons, plugs, and J-plugs mimic baitfish and trigger their instinct to strike out of aggression.
- Fish Near River Mouths: Focus on staging areas where Chinook gather before heading upstream.
- Go Early or Late: Dawn and dusk are prime times when they’re more active near the surface.
Spotlight on Coho Salmon
Coho salmon may be smaller than Chinook, but they make up for it with their agility and aggressive strikes. In September, Coho are also on the move, gathering in similar areas but sometimes striking more readily than their larger cousins.
Tips for Catching Coho in September:
- Troll Fast: Coho respond well to quicker trolling speeds with brightly colored dodgers and flies.
- Use Smaller Baits: Coho often prefer smaller spoons or crankbaits.
- Stay Mobile: If you’re not getting bites, move around to find active schools.
Gear Recommendations for September Salmon
To tackle September Chinook and Coho, having the right gear is essential. Here’s what I recommend:
- Rods & Reels: Medium-heavy trolling rods paired with reels capable of holding at least 200 yards of 20-30 lb test line.
- Line Selection: Braided or monofilament lines work well, but add a fluorocarbon leader for stealth.
- Lures: J-plugs, spoons, and flashers with flies or cut bait rigs.
Pro Tip: Bring a good net—both Chinook and Coho put up a fight, and you don’t want to lose your prize at the boat!
