175-acre lake near Lake County. The lake tops out around 22 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 143 acres of water rimmed by 2.9 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 85% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1 mi long by 0.5 mi wide at the broadest reach. The water lies in Lake County. Closest neighbour on DepthScout: Foreman Lakes, 1 mi west of here.
