76-acre lake near Cook County. The lake tops out around 10 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Lost runs 76 acres with 1.8 miles of edge. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. You'll find it in Cook County. Closest neighbour on DepthScout: Tom, 2 mi northeast of here.
The spring pattern is a shallow one: brook trout in 1 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 2 to 10 ft in winter. Top water on the chart: Deep basin, a deep basin in the 9 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
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 10 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 10 ft chart-limited; documented 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 10 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: splake sit in 2 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 2 to 10 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon at the thermocline or a white tube jig (deep) 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 | 2 to 10 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 3 to 10 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Break off the point (5 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 3 to 10 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait |
| Winter | 2 to 10 ft chart-limited; documented 10 to 45 ft | dawn | Break off the point (5 ft) | Jigging spoon tipped with minnow head, Small white tube |
Start shallow in spring: rainbow trout sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 2 to 10 ft covers winter. The spot to know is Break off the point, a drop-off in about 5 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
