35-acre lake in Chippewa County, Wisconsin. The lake tops out around 9 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 36 acres of water rimmed by 1.6 miles of bank — one island included. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. You'll find it in Chippewa County. Closest neighbour on DepthScout: Withrow Lake, 7 mi north of here.
When the water first warms, yellow perch 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. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run 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 | 2 to 9 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 3 to 9 ft before dropping to 3 to 9 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 9 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 9 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: largemouth bass sit in 2 to 9 ft that time of year. They don't go far with the seasons — 3 to 9 ft covers summer, 3 to 9 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 9 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 9 ft | midday | Break off the point (4 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 3 to 9 ft before dropping to 3 to 9 ft for winter. The spot to know is Deep basin, a deep basin in about 8 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 3 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 9 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. Warm water sends them out to 2 to 9 ft; cold water stacks them in 3 to 9 ft. Shallow bay flat is the standout, a weed flat at roughly 3 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 (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 9 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) | Tungsten ice jig + plastic, Tiny spoon |

Chapman Lake is about 9 ft (3 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, northern pike, largemouth bass, crappie, bluegill on Chapman 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. The interactive chart above rates every spot for each 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.
