39-acre lake near Cook County. The lake tops out around 36 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.
Drawn out, this is 39 acres of water rimmed by 1.4 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 54% of this chart, as modeled. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. The water lies in Cook County. The nearest mapped water is Calf, 0 mi to the east.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (31 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (31 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The chart marks 4 structure features on Cow; the deepest is Deep basin at about 31 ft.
