Rating depth structure for lake trout.

120-acre lake near Cook County. The lake tops out around 80 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
Drawn out, this is 120 acres of water rimmed by 3.1 miles of bank. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 17% of this chart, as modeled. Tip to tip the water measures near 1.4 mi with a 0.3-mi widest point. You'll find it in Cook County. The nearest mapped water is Rat, 1 mi to the northwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 24 to 80 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 68 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 80 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (68 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (20 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (68 ft) | White tube jig, Airplane jig |
