Lake Winnie — Bluebird Sky, Walleyes Still Roaming the Skinny Water

Every fall I build a whole theory around wind. Cloudy and blowing? Walleyes. Sunny and flat? Go home, rake the yard, eat a sad sandwich in the garage. It’s a good theory. Monday on Winnie made it look pretty silly.

Jeff Sundin’s Oct. 20 Fishrapper post covers a Monday, Oct. 19 trip on Big Winnie. The lake was calm, the sky was clear blue, and the sun was high. That’s the kind of day a walleye supposedly sleeps through. They didn’t.

Why a nice day matters

Sundin’s rule of thumb goes like this: if walleyes are eating when the conditions are supposed to be wrong, the good days that follow should be really good. He adds a second test any of us can run from the boat seat. If every boat around you is netting fish, it’s not just you. There’s a real bite on. Monday, with walleyes eating under a bright sun, clearly passed the first one.

His read is that the fall bite has finally shown up, right as his charter calendar runs out. That’s his call on the season. We’re just passing it along.

Where the fish were

• Depth: shallow, roughly 4 to 6 feet. Water clarity is still on the angler’s side: even that shallow, the bottom was hard to see.
• Cover: not much weed left. But the patches that remain, eelgrass and clasping-leaf pondweed, are still green and healthy. That’s where the bait was hiding.
• Dinner: little young-of-the-year perch were tucked right against that green stuff. Every walleye he cleaned was full of them. If you ever wondered what a walleye’s Thanksgiving looks like, it’s that.
• Water temp: 51°F on the surface when they started and 54°F by the time they quit. One day, three degrees. October can’t make up its mind.

What got bit

The walleyes weren’t slamming anything. Sundin calls them semi-aggressive, with bites spaced out just enough that the crew stayed leaning forward, waiting on the next one. Feeling the bite and sticking the fish took real attention. The anglers who watched their line closely caught fish, and on more than one setup.

1. Wiggle worming: a 1/8-oz live-bait jig with half a nightcrawler. This seemed to do best.
2. The same jig with a golden shiner: worked fine. It just finished second.
3. Lindy rig with jumbo golden shiners: got bites, but hooking them was tough. He figures a small stinger hook near the minnow’s tail would have helped. The other two setups were easier, though, so he didn’t bother working it out.

The worm theory (it’s labeled a theory)

Here’s the fun part. Why would a crawler beat a minnow when the lake is full of minnow-sized perch? Sundin and his crew kicked around an idea. The walleyes are eating the same tiny perch all day long, so something that looks totally different might get noticed. A worm is different. So is a big, bright, healthy shiner.

That idea gets a footnote of its own. He says a lot of the bait-shop minnows around this fall haven’t been great, and his goldens come from a private trapper. He’s upfront that he can’t prove any of this. Still, it costs you nothing to find the best bait you can and show the fish something unlike what they’re already eating.

I respect a guide who admits his theory is hard to prove. I’ve been wrong about bait while standing in front of three witnesses.

This week’s outlook

Sundin’s forecast read: nights in the 30s cool the water down, sunny afternoons warm it back up, and that cycle should repeat most of the week. He sees no reason the good fishing would stop. Tuesday, the same crew planned to go after crappies, since their walleyes were already packed for the drive home. He said those details are coming in a later post.

How this fits with the last few cards

• Our Oct. 19 card has the Third River Flowage and River Bar spots in 6 to 9 feet, plus the warning about closed docks and cleaning stations. Keep it for the map and the logistics.
• The Oct. 16 card covers big minnows versus crawlers and the 53 to 54 degree shallows from Oct. 15.
• Use this card for the newest piece: walleyes still feeding shallow on a calm, sunny day, how much the water warms in one afternoon, and the “show them something different” idea.

Fine print

This is one guide’s trip on one very big lake. He gave no fish counts or sizes, and we didn’t add any. The bait theory and the week’s outlook are his opinions, and we’ve labeled them that way. Winnie’s special walleye regulations still apply, so read the current MN DNR fishing regulations before anything goes in the livewell. And check that your landing still has a dock before you back the trailer in.
