I am fishing a 14' hump in the middle of a 24' flat. It is the only vegetation around. The flat is marl bottom. I have caught pike and smallmouth over the flat. I've had several walleye on the camera at 14' among the weeds, but can't trigger a bite. Each trip I've marked and/or seen several. They come in and sniff but don't commit. I've tried still and keeping the jig pattern. I've tried deadstick with blues and with suckers, spoon with minnow head in several colors and sizes, Jigging raps, chubby daughter, acme hyper rattle, basically the kitchen sink. My usual times have been two hours before dark till 20 min after dark. No luck.
I've had tip ups of various depths with large sucker minnows.
Is it more likely they are feeding deeper in the flats? I've marked bait and seen it on camera.
Any thoughts appreciated.
