55-acre lake near Cook County. The lake tops out around 16 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 55 acres of water rimmed by 1.5 miles of bank. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 0.6 mi with a 0.2-mi widest point. The water lies in Cook County. Closest neighbour on DepthScout: Dugout, 1 mi west of here.
When the water first warms, walleye slide up into 4 to 15 ft. Summer is a 5 to 16 ft game here, winter a 5 to 16 ft one. Start at Shoreline break. It's a drop-off holding about 7 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) 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 | 4 to 15 ft | dusk & dawn | Shoreline break (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 16 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Shoreline break (7 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 16 ft chart-limited; documented 12 to 40 ft | dusk & night | Shoreline break (7 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 16 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (14 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 5 to 16 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

Top water on the chart: Shoreline break, a drop-off in the 7 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
