1,138-acre lake in Finland. The lake tops out around 66 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 is how the season plays out for each species, straight from the data behind the map.
Lääminki maps at 1,145 acres behind 19.7 miles of shoreline. With a shoreline index of 4.2, this water is all arms and coves — edge habitat well beyond its acreage. 69% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.

Early season european perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 12 to 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.
| 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, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Break off the point (13 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Break off the point (13 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Break off the point (13 ft) | Tungsten jig + maggots, Small balance jig |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (4 ft) | Tip-ups, Large jigging spoon |
Early season zander use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 13 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a vertical softbait over humps or a deep crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (3 ft) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (13 ft) | Vertical softbait over humps, Deep crankbait |
| Fall | 12 to 40 ft | dusk & night | Break off the point (13 ft) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (56 ft) | Vertical jig / mormyshka with bait, Slow blade bait |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 20 to 66 ft before dropping to 20 to 66 ft for winter. The spot to know is Deep basin, a deep basin in about 56 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (13 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 20 to 66 ft | dawn | Deep basin (56 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (13 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 20 to 66 ft | midday & dawn | Deep basin (56 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for burbot tight to the bank in 20 to 66 ft. There's no big seasonal slide here — summer means 20 to 66 ft, winter 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 56 ft that scores prime in spring. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 66 ft | night & dusk | Deep basin (56 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 20 to 66 ft | night & midday | Deep basin (56 ft) | Heavy jig + cut bait |
| Fall | 20 to 66 ft | night & dusk | Deep basin (56 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (56 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
