215-acre lake in Finland. The lake tops out around 82 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 214 acres wrapped in 5.6 miles of bank. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. 49% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.

Come spring, look for european perch tight to the bank in 3 to 12 ft. They move out to 8 to 28 ft in summer and finish the year down in 12 to 33 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. 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 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow feeding flat (21 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (79 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Shallow feeding flat (21 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 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 (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (21 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Back-bay flat (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (5 ft) | Tip-ups, Large jigging spoon |
Come spring, look for zander tight to the bank in 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Secondary point: a point around 5 ft that scores prime in spring. Best bite is 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 (5 ft) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Summer | 15 to 35 ft | dusk & dawn | Shallow feeding flat (21 ft) | Vertical softbait over humps, Deep crankbait |
| Fall | 12 to 40 ft | dusk & night | Secondary point (5 ft) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (79 ft) | Vertical jig / mormyshka with bait, Slow blade bait |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 25 to 82 ft, and winter fish settle into 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 79 ft, rated prime for summer lake whitefish. Time it for early morning. 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 | 15 to 45 ft | midday & dawn | Shallow feeding flat (21 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 25 to 82 ft | dawn | Deep basin (79 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Secondary point (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (79 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
