Rating depth structure for largemouth bass.
Shared by DepthScout anglers. Exact spots stay private, always.
40-acre lake in Marinette County, Wisconsin. The lake tops out around 18 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What follows comes from the same scoring engine that paints the spots above.
Lost Lake maps at 40 acres behind 1.1 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 86% of the surface on the model — that's where the groceries are. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. Marinette County claims this one. Grass Lake sits 1 mi north — the closest neighbouring chart.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 18 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
The chart marks 4 structure features on Lost Lake; the deepest is Deep basin at about 15 ft.
