1,282-acre lake near Branch County. The lake tops out around 60 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 season-by-season read for each species follows, from the map's own numbers.
The chart traces 8.1 miles of shoreline here. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. 48% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 3.3 mi, about 0.9 mi across. You'll find it in Branch County. For a second option, Lake Bartholomew lies 3 mi southwest.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 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.
