Rating depth structure for lake trout.
Recent public catches load as you reach this section.
73-acre lake near Lake County. The lake tops out around 72 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Species by species, here's what the data says the year looks like.
The outline encloses 73 acres, worked by 1.5 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 29% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.5 mi, about 0.4 mi across. Lake County claims this one. Its nearest charted neighbour, Kek, is 1 mi to the south.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 22 to 72 ft game here, winter an 18 to 72 ft one. Start at Deep basin. It's a deep basin holding about 61 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
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 (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 22 to 72 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (61 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (18 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 72 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (61 ft) | White tube jig, Airplane jig |
