42-acre lake in LaGrange County, Indiana. The lake tops out around 30 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.
The drawn water covers 34 acres wrapped in 1.5 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 52% of this chart. Figure 0.7 mi of water from one end to the other. It sits in LaGrange County. Messick Lake sits 6 mi southeast — the closest neighbouring chart.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 9 to 30 ft one. Start at Shallow bay flat. It's a weed flat holding about 9 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (9 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 9 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
