3,884-acre lake in Finland. The lake tops out around 20 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Vesi piirtyy 1 620 hehtaarin laajuisena, rantaa 53.3 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.7) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 54% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 8 km, leveimmillään 6 km. Vesi sijaitsee alueella Savonlinnan seutukunta. Lähin kartoitettu vesi on Lammunjärvi, 6.4 km etelään.

Early season european perch use the shallows, holding in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Put Break off the point first on the milk run — a drop-off near 6 m that grades prime for summer. 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (0.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Break off the point (6 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (6 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Break off the point (6 m) | Tungsten jig + maggots, Small balance jig |
Come spring, look for northern pike tight to the bank in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Start at Shallow bay flat. It's a weed flat holding about 0.5 m 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Break off the point (6 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Sharp break (5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Main-lake point (2 m) | Tip-ups, Large jigging spoon |
Early season zander use the shallows, holding in 1 to 4.5 m. Expect a summer slide to 4.5 to 11 m, then a winter hold in 6 to 12 m. Put Break off the point first on the milk run — a drop-off near 6 m 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.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Main-lake point (2 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Break off the point (6 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (6 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (6 m) | Vertical jig / mormyshka with bait, Slow blade bait |
The spring pattern is a shallow one: lake whitefish in 4.5 to 14 m. Midsummer fish sit out in 6 to 20 m before dropping to 6 to 20 m for winter. The spot to know is Deep basin, a deep basin in about 20 m 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Break off the point (6 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 6 to 20 m chart-limited; documented 12 to 27 m | dawn | Deep basin (20 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Break off the point (6 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 6 to 20 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (20 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for burbot tight to the bank in 6 to 20 m. Through summer count on 6 to 20 m; the winter hold is 4.5 to 18 m. If you only fish one area, make it Deep basin: a deep basin around 20 m that scores prime in spring. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.

Suurijärvi is about 66 ft (20 m) deep at its deepest point. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Suurijärvi on syvimmillään noin 20 metriä (66 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Suurijärvi. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for northern pike in spring. The interactive chart above rates every spot for each species and season.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Suurijärvi is regulated by the Kalastusrajoitus.fi (official Finnish restriction service). Check the official Finland regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
