6-acre lake in Marinette County, Wisconsin. The lake tops out around 6 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Spruce Lake draws 6 acres inside 0.4 miles of shoreline. Nearly circular (index 1.2), so the story is the bottom, not the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. You'll find it in Marinette County. Closest neighbour on DepthScout: King Lake, 0 mi west of here.
Come spring, look for yellow perch tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. If you only fish one area, make it Deep basin: a deep basin around 5 ft that scores prime in fall. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: largemouth bass in 1 to 6 ft. The depth story barely changes: 2 to 6 ft through summer, 2 to 6 ft in winter. The spot to know is Main-lake point, a point in about 6 ft of water that rates prime for largemouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | dawn & dusk | Main-lake point (6 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 6 ft | dawn & dusk | Break off the point (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 6 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 6 ft | midday | Break off the point (3 ft) | Blade bait, Jigging spoon |
Start shallow in spring: crappie sit in 2 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 5 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 6 ft | dawn & dusk | Break off the point (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 6 ft | dawn | Break off the point (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 6 ft | midday | Deep basin (5 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Winter bluegill concentrate at Deep basin, a prime-rated deep basin around 5 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 6 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 6 ft | midday | Break off the point (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft | midday | Deep basin (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season pumpkinseed use the shallows, holding in 1 to 6 ft. Even in summer they hold at 1 to 6 ft; winter keeps them in 2 to 6 ft. The chart's best answer is Deep basin — deep basin, 5 ft, prime for winter. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 6 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 2 to 6 ft | dusk & dawn | Break off the point (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 6 ft | dawn | Deep basin (5 ft) | Tungsten ice jig + plastic, Tiny spoon |

Spruce Lake is about 6 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 yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on Spruce Lake. 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 5 ft of water that rates prime for yellow perch in fall. Scroll up to the map for the complete spot list by species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
