Rating depth structure for largemouth bass.

10-acre lake in Bayfield County, Wisconsin. The lake tops out around 15 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 10 acres, worked by 0.7 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Call it 0.3 mi long. It sits in Bayfield County. Hildur Lake sits 1 mi west — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Bog Lake hold shallow, usually 2 to 8 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
