Rating depth structure for rainbow trout.

16-acre lake near Cook County. The lake tops out around 36 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Species by species, here's what the data says the year looks like.
Extortion maps at 16 acres behind 1.4 miles of shoreline. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 72% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 0.7 mi end to end. It sits in Cook County. Its nearest charted neighbour, Trip, is 1 mi to the east.
Come spring, look for splake tight to the bank in 5 to 25 ft. Expect a summer slide to 11 to 36 ft, then a winter hold in 8 to 36 ft. Start at Break off the point. It's a drop-off holding about 16 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) 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 | 5 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 11 to 36 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Break off the point (16 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait |
| Winter | 8 to 36 ft chart-limited; documented 10 to 45 ft | dawn | Break off the point (16 ft) | Jigging spoon tipped with minnow head, Small white tube |
Spring rainbow trout on Extortion hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 7 to 36 ft. The chart's best answer is Break off the point — drop-off, 16 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 36 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
In spring, brown trout run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 11 to 36 ft before dropping to 5 to 35 ft for winter. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 16 ft. Fish it in after dark and early morning and you'll meet the bite. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
