Rating depth structure for rainbow trout.

21-acre lake near Cook County. The lake tops out around 23 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
Sock maps at 21 acres behind 0.9 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 56% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.4 mi. It sits in Cook County. If the bite dies, South is 1 mi to the north.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 7 to 23 ft, then a winter hold in 3 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 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 | 7 to 23 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (20 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 | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 6 to 23 ft, and by winter most fish are in 5 to 23 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.

Sock is about 23 ft (7 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target brook trout, rainbow trout on Sock.
Break off the point is the top-rated area: a drop-off in about 10 ft of water that rates prime for rainbow trout in winter. The interactive chart above rates every spot for each species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
