Rating depth structure for brook trout.

7-acre lake in Sawyer County, Wisconsin. The lake tops out around 31 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Smith Lake draws 7 acres inside 0.5 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. 39% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The water lies in Sawyer County. For a second option, Lake Helane lies 2 mi southeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Count 3 structure marks on this chart. The deepest, Deep basin, sits near 26 ft.
