Rating depth structure for lake trout.

58-acre lake near Cook County. The lake tops out around 26 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Jim runs 58 acres with 1.6 miles of edge. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 59% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. The water lies in Cook County. Closest neighbour on DepthScout: Onion, 1 mi north of here.
The spring pattern is a shallow one: lake trout in 7 to 26 ft. The depth story barely changes: 8 to 26 ft through summer, 7 to 26 ft in winter. Top water on the chart: Deep basin, a deep basin in the 22 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
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 26 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 8 to 26 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (22 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 5 to 26 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 7 to 26 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (22 ft) | White tube jig, Airplane jig |
