11-acre reservoir in Jackson County, Wisconsin. The lake tops out around 7 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Lower Wilson Marsh Flowage runs 11 acres with 0.6 miles of edge. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. You'll find it in Jackson County. The nearest mapped water is Big Bear Flowage, 0 mi to the northwest.
When the water first warms, yellow perch slide up into 2 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 2 to 7 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates prime come fall. 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 7 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: crappie in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. The spot to know is Deep basin, a deep basin in about 6 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 7 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 7 ft | dawn & dusk | Break off the point (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 7 ft | dawn | Break off the point (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 7 ft | midday | Deep basin (6 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 7 ft; cold water stacks them in 2 to 7 ft. Deep basin is the standout, a deep basin at roughly 6 ft, rated prime for winter 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 | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 7 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 7 ft | midday | Break off the point (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 7 ft | midday | Deep basin (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
