Rating depth structure for largemouth bass.

95-acre lake in Vilas County, Wisconsin. The lake tops out around 12 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 95 acres of water rimmed by 2.1 miles of bank, with a single island in the mix. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. The water lies in Vilas County. Closest neighbour on DepthScout: Little Spider Lake, 1 mi northwest of here.
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 4 to 12 ft, wintering in 4 to 12 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. 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 | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |

Trilby Lake is about 12 ft (4 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 Trilby 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Open the map above to see every rated spot for each 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.
