15-acre lake in Bayfield County, Wisconsin. The lake tops out around 15 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 15 acres wrapped in 1 miles of bank. With a 1.8 development index there's bank structure worth casting at, in moderation. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Bayfield County. Its nearest charted neighbour, Twin Lakes, is 0 mi to the north.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 5 to 15 ft before dropping to 5 to 15 ft for winter. The spot to know is Deep basin, a deep basin in about 13 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 5 to 15 ft. Start at Deep basin. It's a deep basin holding about 13 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.

|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
