35-acre reservoir in Jackson County, Wisconsin. The lake tops out around 9 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
On the chart, Wilson Marsh Flowage draws 35 acres inside 1.4 miles of shoreline. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. You'll find it in Jackson County. Closest neighbour on DepthScout: Lower Wilson Marsh Flowage, 0 mi northwest of here.
Come spring, look for yellow perch tight to the bank in 2 to 9 ft. Through summer count on 3 to 9 ft; the winter hold is 3 to 9 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. 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 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) |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 3 to 9 ft; cold water stacks them in 3 to 9 ft. Top water on the chart: Deep basin, a deep basin in the 8 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 | 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 |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 2 to 9 ft before dropping to 3 to 9 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 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 | 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 |
