Rating depth structure for largemouth bass.
Shared by DepthScout anglers. Exact spots stay private, always.
5-acre lake in Lincoln County, Wisconsin. The lake tops out around 45 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
On the chart, Pier Lake draws 5 acres inside 0.4 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 21% of the water is 15 ft or less as modeled, the band where the food chain lives. The water lies in Lincoln County. Closest neighbour on DepthScout: Moraine Lake, 0 mi northeast of here.
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Top water on the chart: Main-lake point, a point in the 11 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (11 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (11 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (20 ft) | Blade bait, Jigging spoon |

Pier Lake is about 45 ft (14 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 largemouth bass on Pier Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Main-lake point is the top-rated area: a point in about 11 ft of water that rates prime for largemouth bass in fall. The map above holds the full rated-spot list for every species and season.
For largemouth bass, 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.
