460-acre lake near Martin County. The lake tops out around 10 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. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 460 acres of water rimmed by 6.1 miles of bank. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1.6 mi, about 1.2 mi across. You'll find it in Martin County. For a second option, Clam lies 4 mi east.
When the water first warms, walleye slide up into 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft.
