16-acre lake in Dubois County, Indiana. The lake tops out around 18 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 19 acres of water rimmed by 0.7 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 95% of this chart. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. You'll find it in Dubois County. Closest neighbour on DepthScout: Ferdinand State Forest Lake, 4 mi northeast of here.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
