40-acre reservoir in Ohio. The lake tops out around 9 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 40 acres wrapped in 1 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. Fulton Pond sits 4 mi east — the closest neighbouring chart.
Early season largemouth bass use the shallows, holding in 2 to 9 ft. Even in summer they hold at 3 to 9 ft; winter keeps them in 3 to 9 ft. Put Main-lake point first on the milk run — a point near 5 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
