Rating depth structure for brook trout.

8-acre lake in Bayfield County, Wisconsin. The lake tops out around 21 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 8 acres of water rimmed by 0.5 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 46% of the surface on the model — that's where the groceries are. The water lies in Bayfield County. For a second option, Middle Eau Claire Lake lies 1 mi north.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 6 to 21 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 18 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 21 ft | dawn & dusk | Deep basin (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (18 ft) | Small jigging spoon, Tungsten jig + plastic |
