49-acre lake in Douglas County, Wisconsin. The lake tops out around 16 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
The outline encloses 49 acres, worked by 1.5 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 85% of this chart, as modeled. End to end it runs roughly 0.5 mi, about 0.3 mi across. Douglas County claims this one. If the bite dies, Red Lake is 1 mi to the north.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 5 to 16 ft, wintering in 5 to 16 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| 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 | 5 to 16 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring crappie on Crotty Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. The chart's best answer is Deep basin — deep basin, 14 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).
| 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 | 5 to 16 ft | dawn & dusk | Break off the point (7 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 16 ft | dawn | Break off the point (7 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 16 ft | midday | Deep basin (14 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Crotty Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 5 to 16 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
| 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 | 5 to 16 ft | midday | Break off the point (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft | midday | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft | dawn | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |
