456-acre lake near Jackson County. The lake tops out around 6 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 456 acres of water rimmed by 4.1 miles of bank. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1.2 mi, about 1 mi across. You'll find it in Jackson County. For a second option, Heron (South Heron) lies 2 mi southwest.
When the water first warms, walleye slide up into 2 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 2 to 6 ft.

Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
