They're getting a bit sluggish, right? Seems a bit late for baitfish to be that far up. When it gets a little cooler the eyes will probably disappear for bigger water, following the forage. I'd use a spinner rig with a big thumpin' blade and tip the hook with a minnow. If you want all artificial try a minnow replica nose hooked. I haven't fished there but have other places up north, each time with a guide. All of them made their own spinners, adjusting until they got the right combination.

. But the blade is a bit too small, as seems to be the usual for store-bought spinners, and the hook ought to be a heavier wide gap octopus style even if using soft plastics. Try a Colorado blade in silver or gold one or two sizes larger in that clear water. Play around with beads, more or less, different colors and sizes, too. That is unless you are buying them made up. The deal about that is I remember many times putting in hours of fishing with no walleye bites, the baits being changed every few minutes. I'd cast and troll, then swing the bait in for another version, let him tie it on almost instantly, then sling it back out. A little different blade, or some other part would make all the difference. That is, assuming the fish are there. We didn't fish anywhere there wasn't a lot of some kind of baitfish in abundance. Be ready to look way farther downstream for the eyes.
Fish it slow. A big Colorado blade lets you do that, perfect for eyes.
