18-acre lake in Bayfield County, Wisconsin. The lake tops out around 22 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. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 18 acres of water rimmed by 0.9 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. 44% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Bayfield County. Closest neighbour on DepthScout: Pickerel Lake, 1 mi east of here.
Spring yellow perch on Idlewild Lake hold shallow, usually 3 to 12 ft. They move out to 7 to 22 ft in summer and finish the year down in 7 to 22 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. 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) |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 7 to 22 ft; cold water stacks them in 7 to 22 ft. Deep basin is the standout, a deep basin at roughly 19 ft, rated prime for winter crappie. Plan around early morning and the evening in the warm months. 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. Midsummer fish sit out in 4 to 15 ft before dropping to 7 to 22 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for bluegill in spring. Plan around early morning and the evening in the warm months. 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 |

Keep a micro tube or a sponge spider (fly) rigged through the warm months.
