Rating depth structure for largemouth bass.

7-acre pond in Adams County, Wisconsin. The lake tops out around 5 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 7 acres of water rimmed by 0.7 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.3 mi. The water lies in Adams County. For a second option, Mason Lake lies 2 mi east.
In spring, rainbow trout run shallow here, mostly 1 to 5 ft. Summer keeps them at 1 to 5 ft, and they winter in 1 to 5 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 1 to 5 ft | dawn & dusk | Break off the point (2 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 1 to 5 ft | dawn | Break off the point (2 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, yellow perch slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. If you only fish one area, make it Deep basin: a deep basin around 4 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft | dawn | Deep basin (4 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft | midday | Deep basin (4 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft | midday & dawn | Deep basin (4 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: largemouth bass sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. The spot to know is Main-lake point, a point in about 5 ft of water that rates prime for largemouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 5 ft | dawn & dusk | Break off the point (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 1 to 5 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 5 ft | midday | Break off the point (2 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: crappie in 1 to 5 ft. The depth story barely changes: 2 to 5 ft through summer, 2 to 5 ft in winter. Top water on the chart: Deep basin, a deep basin in the 4 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 5 ft | dawn & dusk | Break off the point (2 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 5 ft | dawn | Break off the point (2 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 5 ft | midday | Deep basin (4 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts bluegill in skinny water — 1 to 5 ft is the zone. Summer fish stay in 1 to 5 ft, and winter fish hold in 2 to 5 ft. Winter bluegill concentrate at Deep basin, a prime-rated deep basin around 4 ft. Warm-month bites cluster around early morning and the evening. 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 5 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 1 to 5 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 5 ft | midday | Break off the point (2 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 5 ft | midday | Deep basin (4 ft) | Tungsten ice jig + plastic, Tiny spoon |

Big Spring Pond is about 5 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target rainbow trout, yellow perch, largemouth bass, crappie, bluegill on Big Spring Pond. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Deep basin is the top-rated area: a deep basin in about 4 ft of water that rates prime for yellow perch in fall. Open the map above to see every rated spot for each species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
