Rating depth structure for brook trout.
Shared by DepthScout anglers. Exact spots stay private, always.
11-acre lake in Bayfield County, Wisconsin. The lake tops out around 40 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Nymphia Lake draws 11 acres inside 0.7 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. 31% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. You'll find it in Bayfield County. For a second option, Star Lake lies 1 mi west.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 18 ft, rated prime for summer brook trout. Time it for early morning and the evening. 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 (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
