Rating depth structure for largemouth bass.
Shared by DepthScout anglers. Exact spots stay private, always.
16-acre lake in Marinette County, Wisconsin. The lake tops out around 28 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
Wonder Lake maps at 16 acres behind 1 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 59% of the surface on the model — that's where the groceries are. The basin spans about 0.4 mi end to end. It sits in Marinette County. Fryingpan Lake sits 1 mi southeast — the closest neighbouring chart.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 8 to 28 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is 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 | 8 to 20 ft | dawn & dusk | Main-lake 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 | 8 to 28 ft | midday | Deep basin (24 ft) | Blade bait, Jigging spoon |
Count 4 structure marks on this chart. The deepest, Deep basin, sits near 24 ft.
