30-acre lake in Vigo County, Indiana. The lake tops out around 9 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 the data behind the map says about each species, season by season:
The chart traces 1.3 miles of shoreline here. Nearly circular (index 1.2), so the story is the bottom, not the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 0.5 mi of water from one end to the other, 0.3 mi at the beam. Vigo County claims this one. Its nearest charted neighbour, Bell Pond, is 8 mi to the west.
When the water first warms, largemouth bass slide up into 2 to 9 ft. There's no big seasonal slide here — summer means 3 to 9 ft, winter 3 to 9 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in 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 9 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 9 ft | dawn & dusk | Shallow bay flat (4 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 9 ft | midday & dawn | Main-lake point (2 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 9 ft | midday | Break off the point (3 ft) | Blade bait, Jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 2 to 9 ft game here, winter a 3 to 9 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 9 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 9 ft | midday | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, channel catfish slide up into 2 to 9 ft. There's no big seasonal slide here — summer means 3 to 9 ft, winter 3 to 9 ft. If you only fish one area, make it Deep basin: a deep basin around 8 ft that scores prime in winter. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dusk | Shallow bay flat (4 ft) | |
| Summer | 3 to 9 ft | night & dusk | Deep basin (8 ft) | |
| Fall | 3 to 9 ft | dusk | Deep basin (8 ft) | |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) |
