181-acre lake in Finland. The lake tops out around 20 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.
The drawn water covers 182 acres wrapped in 4.9 miles of bank. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 92% of the water is 15 ft or less, the band where the food chain lives.

Come spring, look for european perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 ft of water and rates prime come fall. 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 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 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 8 to 20 ft, then a winter hold in 5 to 15 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) |

Come spring, look for zander tight to the bank in 4 to 15 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (4 ft) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Summer | 6 to 20 ft | dusk & dawn | Break off the point (6 ft) | Vertical softbait over humps, Deep crankbait |

| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 ft) | Vertical jig / mormyshka with bait, Slow blade bait |
In spring, lake whitefish run shallow here, mostly 6 to 20 ft. There's no big seasonal slide here — summer means 6 to 20 ft, winter 6 to 20 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 20 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 | 6 to 20 ft | midday & dawn | Break off the point (6 ft) | Small jig + waxworm, Blade bait (small) |
