61-acre lake in Waupaca County, Wisconsin. The lake tops out around 22 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Long Lake draws 61 acres inside 1.4 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 67% of this chart, as modeled. Figure 0.6 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Waupaca County. For a second option, Siemer Lake lies 0 mi west.
Spring yellow perch on Long Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 7 to 22 ft, and by winter most fish are in 7 to 22 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 22 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 7 to 22 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 7 to 22 ft | midday | Shoreline break (10 ft) | Blade bait, Jigging spoon |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 7 to 22 ft, wintering in 7 to 22 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 19 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| 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 | 7 to 22 ft | dawn & dusk | Shoreline break (10 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shoreline break (10 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 7 to 22 ft | midday | Deep basin (19 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 4 to 15 ft, wintering in 7 to 22 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| 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 | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shoreline break (10 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 7 to 22 ft | midday | Deep basin (19 ft) | Tungsten ice jig + plastic, Tiny spoon |
