125-acre lake near Cook County. The lake tops out around 5 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Species by species, here's what the data says the year looks like.
On the chart, Mark draws 125 acres inside 3 miles of shoreline. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 1.2 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Cook County. The nearest mapped water is Turtle, 1 mi to the southwest.
When the water first warms, yellow perch slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm 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 | 1 to 5 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (4 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (4 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (4 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 1 to 5 ft. The depth story barely changes: 2 to 5 ft through summer, 2 to 5 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
