609-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. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Suuri Humalajärvi draws 621 acres inside 11.2 miles of shoreline. That shoreline is heavily fingered (development index 3.2) — bays, points and pockets everywhere, which multiplies the fishable edge. About 70% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.

The spring pattern is a shallow one: european perch in 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 12 to 33 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for european perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) gets it done.
| 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 | 8 to 28 ft | dawn | Shallow bay flat (2 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (65 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Deep basin (65 ft) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| 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) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (4 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: zander in 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. The spot to know is Main-lake point, a point in about 4 ft of water that rates prime for zander in spring. Plan around the evening and early morning in the warm months. Summer baits: a vertical softbait over humps or a deep crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Summer | 15 to 35 ft | dusk & dawn | open water | Vertical softbait over humps, Deep crankbait |
| Fall | 12 to 40 ft | dusk & night | Main-lake point (4 ft) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (65 ft) | Vertical jig / mormyshka with bait, Slow blade bait |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 20 to 66 ft, then a winter hold in 20 to 66 ft. Put Deep basin first on the milk run — a deep basin near 65 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 20 to 66 ft | dawn | Deep basin (65 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (4 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 20 to 66 ft | midday & dawn | Deep basin (65 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 20 to 66 ft is the zone. Summer keeps them at 20 to 66 ft, and they winter in 15 to 60 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 65 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 66 ft | night & dusk | Deep basin (65 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
