Rating depth structure for lake trout.

51-acre lake near Cook County. The lake tops out around 75 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here's the year, species by species, as the scoring engine sees it.
On the chart, Powell draws 51 acres inside 1.7 miles of shoreline. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. The shallow band under 15 ft claims about 31% of the surface on the model — that's where the groceries are. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. You'll find it in Cook County. Closest neighbour on DepthScout: Fern, 1 mi southeast of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 23 to 75 ft before dropping to 19 to 75 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 64 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 (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 23 to 75 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (64 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 19 to 75 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (64 ft) | White tube jig, Airplane jig |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 64 ft.
