2,073-acre lake near Otsego County. The lake tops out around 23 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. Below is the species-by-species picture, pulled from the same data the map uses.
Otsego Lake maps at 2,050 acres behind 10.6 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Roughly 79% of the water is 15 ft or less, the band where the food chain lives. Call it 4.7 mi long by 1.2 mi wide at the broadest reach. It sits in Otsego County.
