86-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. What the data behind the map says about each species, season by season:
The drawn water covers 86 acres wrapped in 2.6 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. 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. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. Start at Back-bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in 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 | Back-bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 3 to 10 ft, then a winter hold in 3 to 10 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in 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) |

In spring, lake whitefish run shallow here, mostly 3 to 10 ft. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 10 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Break off the point (5 ft) | Small jig + waxworm, Blade bait (small) |
