47-acre lake near Cook County. The lake tops out around 15 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
The drawn water covers 47 acres wrapped in 2.2 miles of bank. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The basin spans about 1 mi end to end and 0.2 mi across at its widest. It sits in Cook County. If the bite dies, Dunn is 0 mi to the north.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Through summer count on 5 to 15 ft; the winter hold is 2 to 15 ft. Start at Deep basin. It's a deep basin holding about 13 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (13 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 15 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (13 ft) | Small jigging spoon, Tungsten jig + plastic |
