25-acre lake in Hancock County, Ohio. The lake tops out around 11 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. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 32 acres, worked by 1.3 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.6 mi end to end. It sits in Hancock County. Its nearest charted neighbour, Veterans Memorial Lake, is 2 mi to the south.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is a 3 to 11 ft game here, winter a 3 to 11 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
