34-acre lake in Finland. The lake tops out around 10 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 34 acres wrapped in 2.9 miles of bank. With a shoreline index of 3.6, this water is all arms and coves — edge habitat well beyond its acreage. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout.

Come spring, look for european perch tight to the bank in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. If you only fish one area, make it Deep basin: a deep basin around 9 ft that scores prime in fall. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 10 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 3 to 10 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 3 to 10 ft game here, winter a 3 to 10 ft one. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |

You won't need more than a blade bait vertical or a small jigging spoon most summer days.
