6-acre lake in Bayfield County, Wisconsin. The lake tops out around 64 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here's the year, species by species, as the scoring engine sees it.
Overby Lake maps at 6 acres behind 0.4 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 14% of this chart, as modeled. It sits in Bayfield County. Its nearest charted neighbour, Esox Lake, is 0 mi to the west.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 19 to 64 ft, and by winter most fish are in 16 to 64 ft. If you only fish one area, make it Deep basin: a deep basin around 54 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 19 to 64 ft | dawn | Deep basin (54 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (16 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 16 to 64 ft | dawn | Deep basin (54 ft) | White tube jig, Airplane jig |
