8-acre lake in Sullivan County, Indiana. The lake tops out around 12 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's the year, species by species, as the scoring engine sees it.
The chart traces 0.9 miles of shoreline here. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. You'll find it in Sullivan County. Closest neighbour on DepthScout: Gambill Lake, 1 mi north of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 4 to 12 ft before dropping to 4 to 12 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Shallow bay flat (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for bluegill in spring. Plan around early morning and the evening in the warm months. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
