Rating depth structure for brook trout.
Recent public catches load as you reach this section.
32-acre lake near Cook County. The lake tops out around 3 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Circle draws 32 acres inside 0.9 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. You'll find it in Cook County. For a second option, Musquash lies 1 mi east.
Start shallow in spring: brook trout sit in 1 to 3 ft that time of year. They don't go far with the seasons — 1 to 3 ft covers summer, 1 to 3 ft covers winter. The spot to know is Deep basin, a deep basin in about 3 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
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 3 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 1 to 3 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (3 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 3 ft chart-limited; documented 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 1 to 3 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (3 ft) | Small jigging spoon, Tungsten jig + plastic |
