37-acre lake in Manitowoc County, Wisconsin. The lake tops out around 60 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 37 acres, worked by 1.2 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. About 31% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. Manitowoc County claims this one. If the bite dies, Weyers Lake is 0 mi to the southeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 10 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (10 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Back-bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (7 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (10 ft) | Tip-ups, Large jigging spoon |
Spring largemouth bass on Hartlaub Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 10 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (10 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

| Winter | 15 to 35 ft | midday | Break off the point (28 ft) | Blade bait, Jigging spoon |
Early season crappie use the shallows, holding in 2 to 8 ft. Expect a summer slide to 10 to 25 ft, then a winter hold in 15 to 35 ft. Put Back-bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (7 ft) | 1/16 oz jig + tube, Curly-tail grub |

Early season bluegill use the shallows, holding in 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. The chart's best answer is Shallow bay flat — weed flat, 10 ft, prime for summer. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (7 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
