Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
15-acre lake in Dubois County, Indiana. The lake tops out around 16 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
New Holland Lake's chart carries 0.8 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. 97% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. You'll find it in Dubois County. For a second option, Old Holland Lake lies 0 mi east.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Top water on the chart: Shallow bay flat, a weed flat in the 4 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 16 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (4 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 16 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (16 ft) | Blade bait, Jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. Warm water sends them out to 4 to 15 ft; cold water stacks them in 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring bluegill. Plan around early morning and the evening in the warm months. A small sponge spider (fly) or a micro tube jig covers the summer program.

| 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 | 4 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 16 ft chart-limited; documented 6 to 18 ft | midday | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (16 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. The spot to know is Deep basin, a deep basin in about 16 ft of water that rates prime for crappie in winter. Plan around early morning and the evening in the warm months. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
