100-acre lake in LaGrange County, Indiana. The lake tops out around 82 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 95 acres wrapped in 1.6 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 12% of this chart. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. It sits in LaGrange County. Royer Lake sits 1 mi southwest — the closest neighbouring chart.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 7 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (7 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (18 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (18 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Start at Shallow bay flat. It's a feeding flat holding about 7 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (7 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow bay flat (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for channel catfish tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 24 ft that scores prime in summer. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (7 ft) | |
| Summer | 8 to 25 ft | night & dusk | Creek inflow (24 ft) | |
| Fall | 10 to 30 ft | dusk | Shallow bay flat (7 ft) | |
| Winter | 20 to 40 ft | midday | open water |
Spring common carp on Fish Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 3 to 15 ft, and by winter most fish are in 10 to 30 ft. The chart's best answer is Shallow bay flat — feeding flat, 7 ft, prime for spring. Prime time lands in early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (7 ft) | |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | |
| Fall | 5 to 18 ft | midday | Shallow bay flat (7 ft) | |
| Winter | 10 to 30 ft | midday | open water |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a feeding flat holding about 7 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (7 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow bay flat (7 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (7 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | open water | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Shallow bay flat, a feeding flat in about 7 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (7 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (7 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
