Rating depth structure for lake trout.

23-acre lake near Cook County. The lake tops out around 27 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 23 acres of water rimmed by 0.9 miles of bank. 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. The shallow band under 15 ft claims about 46% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.4 mi, about 0.2 mi across. You'll find it in Cook County. The nearest mapped water is Thrush, 0 mi to the northwest.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 8 to 27 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 23 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
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 | 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 27 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (23 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 (12 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake trout run shallow here, mostly 7 to 27 ft. Summer keeps them at 8 to 27 ft, and they winter in 7 to 27 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 23 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 | 7 to 27 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Shoreline break (12 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 8 to 27 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (23 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 5 to 27 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Shoreline break (12 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 7 to 27 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (23 ft) | White tube jig, Airplane jig |
Spring puts splake in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 8 to 27 ft; cold water stacks them in 6 to 27 ft. Shoreline break is the standout, a drop-off at roughly 12 ft, rated prime for summer splake. Plan around early morning and the evening in the warm months. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
