21-acre lake in Oconto County, Wisconsin. The lake tops out around 18 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. What the data behind the map says about each species, season by season:
Drawn out, this is 21 acres of water rimmed by 0.9 miles of bank. Nearly circular (index 1.4), so the story is the bottom, not the bank. Roughly 75% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. You'll find it in Oconto County. The nearest mapped water is Lower Island Lake, 1 mi to the west.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 15 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 | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 18 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 18 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 18 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. The spot to know is Main-lake point, a point in about 8 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 | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 18 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Deep basin, a deep basin in the 15 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 8 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 18 ft | dawn | Break off the point (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 5 to 18 ft for winter. Winter bluegill concentrate at Deep basin, a prime-rated deep basin around 15 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 | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Tungsten ice jig + plastic, Tiny spoon |

Camp Four Lake is about 18 ft (5 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 on Camp Four 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 15 ft of water that rates prime for yellow perch in fall. Every other rated spot, per species and season, is on the map above.
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.
Fishing on Camp Four Lake is regulated by the Wisconsin DNR. Check the official Wisconsin regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
