371-acre natural lake near LaGrange. The lake tops out around 90 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 371 acres of water rimmed by 4.7 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 14% of this chart. End to end it runs roughly 1.1 mi, about 0.9 mi across. You'll find it in LaGrange County. The nearest mapped water is Olin Lake, 1 mi to the southeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Main-lake point is the standout, a point at roughly 11 ft, rated prime for fall largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
