18-acre lake in Clark County, Indiana. The lake tops out around 21 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.
Traced from the shoreline, Schlamm Lake runs 23 acres with 0.8 miles of edge. 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. Roughly 90% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.3 mi end to end. The water lies in Clark County. The nearest mapped water is Deam Lake, 8 mi to the southwest.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 6 to 21 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |

Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
